The member companies have a lot to offer: an exceptional expertise – both at home and abroad - for you to benefit from and covering the whole range of water treatment technologies. From physical-chemical treatment and (an)aerobics, to sand and membrane filtration, and use of activated carbon. Several companies have also extended their operations to cover the complete water cycle. Some concentrate on process water production, the re-use of the treated wastewater effluent and on drinking water production. For sludge processing, TNAV companies developed drying and incineration techniques of their own. In the last few years and in a context of skyrocketing fuel prices, several, if not most companies have turned to the generation of renewable energy and energy recovery. Flow of technology Actively involved in research programmes with engineering and biochemistry departments of leading universities and institutes, the TNAV companies are well-positioned to suggest you a wide range of science-based solutions and the best available technologies to solve your wastewater problem. The TNAV companies are used to work with and for practically any industrial sector. They will treat manure and wastewater from slaughterhouses alike, they are used to treat large volumes of effluent from car plants, from food processing, chemical or textiles factories, from public swimming pools and municipal wastewater. Flexibility is key and the solutions offered by the TNAV members are always tailor-made to suit your or your company’s needs. Having gathered a considerable amount of experience throughout Europe and beyond, the TNAV members are fully prepared to work as subcontractors or to form ad hoc alliances with local building contractors. 4 A strongly developed network From the start it has been TNAV’s mission to build a strong network. Members, be they technology providers, suppliers, engineering companies, general contractors or knowledge centres, all contribute to and benefit from what we call the flow of technology. Innovation is TNAV’s �raison d’être’. Our network provides the context for innovation through common research programmes, willingness to share new insights and findings in workshops and seminars. Our members are keen to apply technological findings in their work as professional problemsolvers. They have to if they want to maintain or improve their competitiveness. So, at the end of the day it is you, the customer and/or industrial partner, who benefits most from this technology flow. I am sure that this booklet will help you find the water-treatment partner(s) you’ve been looking for ! Luc Geuens TNAV Chairman Luc Geuens is professor and researcher at the Karel de Grote-Hogeschool in Antwerp (Belgium) 1 TNAV: a Dutch acronym for: “Thematisch Netwerk Afvalwaterzuiveringstechnologie Vlaanderen”, i.e. Wastewater Technology Network of Flanders 5 Tank terminal Aaqua 6 Aaqua Waste Water Technology nv Kievitlaan 6 B 2820 Bonheiden Phone:+32 (0) 15 33 17 58 Fax: + 32 15 33 17 57 E-mail: [email protected] URL: www.aaqua.com Common sense and technological know how In short AAQUA is a small and dynamic company, based near Mechelen (northern part of Belgium) with annual sales of EUR 2 million: nothing much when compared with multinational companies such as General Electric or Siemens, but the five highly skilled and experienced engineers of AAQUA are extremely busy and have earned themselves an enviable reputation in the design, engineering and construction of wastewater treatment plants. They also strongly believe that small is beautiful and do not want to grow at all costs. Marc Feyten, General Manager A closer look The AAQUA team may be small, but its constituent members have more than 25 years of experience in all water treatment technologies as well as in the design of the water treatment tools. Being typical technology providers, the AAQUA team very much favours a hands on approach. If at all possible, they will prefer practical solutions to sophisticated technologies. They want to see, feel, experience on the spot and are not afraid of dirtying their hands. They will discuss at length with the customer to see what his/her real needs are and will go for the best possible solution. Of course, AAQUA has to work with subcontractors: construction workers, welders, electro-technicians, etc…but the company is the customer’s one stop shop and ensures that his water and/or sludgerelated problem is solved efficiently. Needless to say: AAQUA remains available after delivery. “We are doing very well”, CEO Marc Feyten says, “We feel that there is a growing awareness among our and our competitors’ customers that water treatment is a necessity. They feel that the reuse of wastewater as process water makes sense, both in terms of sustainability as well as costeffectiveness”. One of the more rewarding AAQUA specialties is the wastewater treatment of trankcleaning facilities. A very challenging job as these are complex types of wastewater, submitted to stringent health and environ“Not long ago a small slaughtermental regulations. house asked us to take care of its Even if the company does not want to conquer the wastewater problem: it produced … market, let alone the world, it is ambitious and eager to 5 cubic metres of wastewater a day. come to grips with new problems. The newest challenges Still, they gave us carte blanche. We are the bio-ethanol plant in the harbour area of Ghent developed an affordable solution (Belgium) and a biodiesel plant in Rotterdam. AAQUA is and everybody was happy with the currently designing the wastewater installations for both result.” plants. 7 When we ask what AAQUA’s Unique Selling proposition might be, Marc Feyten replies: “We try to keep it simple and at the same time to be creative in order to work out the most efficient and affordable solution for our customers. For us, every single job is a new challenge, just as important as the previous or the next one”. The AAQUA team is fully aware that service is vitally important today. “Simple software on my PC at home”, Marc Feyten explains, “ allows me to monitor Unique Selling Proposition: all the computer controlled water treatment facilities, to We try to keep it simple and at the for example start up or turn off the pumps, whenever it is same time to be creative in order to necessary. In case of emergency I receive a warning SMS on work out the most efficient and afmy mobile phone, and can act at once. If they want it, we fordable solution for our customers. propose exactly the same service to our customers. ” Technologies AAQUA focuses on the following techniques, all of their own design: 1.Mechanical sieves such as screw screens, curved screens, AAQUA-RS rotary screens with internal and external feeding 2.Sedimentation with plate pack 3.Physical-chemical treatment through addition of coagulants and flocculants. 4.Flotation with Dissolved Air Flotation (DAF) - The AAQUA-DAF flotation-unit as pre-treatment - The AAQUA-DAF flotation-unit as a separator of activated sludge. This is a compact and more reliable alternative to the traditional clarifier. 5.Biological treatment with hyperbolic-aeration and fully automated with PLC-controller, SCADA supervision; data-registration of important process variables. 6.Sludge treatment such as mineralization, gravitational dewatering, centrifuge, belt filter press, dewatering bags. DISSOLVED AIR FLOTATION (DAF) Dissolved air flotation systems are designed to remove fats, oils and grease (FOG), suspended solids (TSS), biological oxygen demand (BOD), food/animal production/processing wastes, industrial wastes, hydrocarbon oils/emulsions and many other contaminants. Clarification rates as high as 97% or more can be achieved using these systems. DAF is the process of removing suspended solids, oils and other contaminants via the use of air bubble flotation. Air is dissolved into water, mixed with the waste stream and released from solution while in intimate contact with the contaminants. Air bubbles form, attach to the solids, increase their buoyancy and float the solids to the water’s surface where they are mechanically skimmed and removed into an internal hopper for further handling. This handling may include a belt filter press or decanter. A percentage of the clean effluent is recycled and supersaturated with air, mixed with the wastewater influent and injected into the DAF separation chamber. 8 The AAQUA-DAF is a fairly new combination of aerobic treatment with a SBR (Sequencing Batch Reactor). 1.Physical-chemical pre-treatment 2.Pre-thickening of biological drain sludge 3.Effluent polishing (elimination of volatile compounds and recalcitrant COD Those three processes are executed successively.

Over the years, it has developed a mutually beneficial relationship with Cofido, consolidated by means of a cross shareholdership. Cofido, a small but equally dynamic company based at Chaudfontaine near Liège, in the Walloon part of Belgium, basically is a project developer and proved to be a perfect match for Aquitec. Both small Ronny Van Hee, companies, employing 15, so far have no reason to regret having joined their General Manager forces: their revenues have been growing steadily from EUR 1 million in 2005 to approximately EUR 3 million in 2007. By 2010, the EUR 5 million target should be within reach, says Ronny Van Hee, General Manager of Aquitec. A closer look “True, Aquitec is going its own way. In the near future the company intends to start up an activity best described as steel framed construction for private homes and industrial purposes. It is probably the most innovative, resource-efficient housing technique currently available”, Van Hee asserts: “Because of their faster construction, strength, versatility, and reduced costs, steel buildings offer an attractive alternative to traditional wood or concrete”. Anyhow, water treatment activities will remain the core Unique Selling Proposition: activity of the joint companies: “Our order book is quite Our network is our strength. And we full. Aquitec and Cofido combined are currently supervising also work until we find the best poseighteen different projects both in Belgium and abroad. sible solution for the customer, also We are fully booked for almost one year from now,” says where others tend to give up. Van Hee. Contrary to most TNAV-members, however, Aquitec-Cofido does not want to be the best in say: membrane technology. “No, it is not our priority as yet. Several of our colleagues are dealing with water reuse and reversed osmosis, and they are doing an excellent job, so why should we try to duplicate them ?” Van Hee wonders. “If one of our customers wants advanced filtration, we will – for the time being - be happy to outsource this part of the job to our colleagues”. The company continues to concentrate on environmental and sustainable water treatment technologies, civil works and the industry. 11 Among the main customers we unsurprisingly find Aquafin, the company building and operating all supra-municipal wastewater treatment infrastructure in Flanders. Most of Aquafin’s larger wwtps (wastewater treatment plants) have been completed by now, and Aquitec contributes to the building of small-scale plants and to the modernisation and extension of sewerage systems for Aquafin. Aquitec also builds wwtps for hospitals, office buildings and for the industry. For the Belgian army, Aquitec equipped two containers with moveable biorotors for a military mission to Chad (Africa). They will be used to treat the wastewater produced by 200 men. “Biorotors are one of our specialties”, Van Hee says, “they continue to be tremendously successful, probably because they are quite simple to handle and require little maintenance”. “A biorotor is a slowly rotating cylinder which is horizontally positioned and partly immersed in the water to be treated. As the rotor rotates slowly, a number of discs alternately sink in the water/waste water so as to get the bacteria moist and rises up in the air wherein there is plenty of oxygen available for an efficient bacterial activity to take place in a thin film of water. This promotes the interchange of water and air into the biomass carrying out the oxidation as well as the decomposition of organic waste matter taking place under natural conditions. The internal structure of the cylinder is intended to provide the widest possible area for the bacteria to get attached to”. (www.wipo.org, the site of the World Intellectual Property Organisation) Another reference is the SAF wastewater treatment unit built for the brand new terminal of rapidly expanding Charleroi (or Brussels-South) airport (3000 i.e.). But the Aquitec-Cofido alliance clearly looks beyond the borders of the small country that is Belgium. In the recent past, Aquitec has been building two wwtps for cooperative farms in the Champagne region in France. “We are the only company to use concrete aeration tanks over there (of considerable dimensions: 5 meter high and with a diameter of 50 meters). Even so, the system is compact when you compare it with the stabilisation ponds the French winegrowers still use and it is much easier to monitor the aeration process,” says Van Hee. That is not all. Aquitec/Cofido is building a wastewater treatment unit in Morocco and recently, Cofido Mali has been created. The Sahel republic of Mali is not yet ready for wastewater treatment and would be happy to provide its population with potable water in the first place. Cofido Mali does not want to suggest it can Champagne Region, France, active sludge installation, wwtp winegrowers’ cooperative 12 solve this problem all by itself, but the company is negotiating a contract with the Malinese authorities for the drilling of some 5000 wells. By April 2008, more than 70 wells had been delivered. Through business-connections, and we all know now that networking can be useful, in creating business, Aquitec-Cofido is also preparing to enter the Brazilian market, but it would be premature at this stage , so we are told, to go into further detail about this.

At the time, the company exclusively dealt with water softening. Even today, water softening both for industrial and domestic applications is Bayard’s major activity: 70% in terms of sales. Over the years, the 30 people employed by Bayard have sold and installed some 40,000 water softening units in Belgium, Luxemburg and Northern France. Today, they still sell about 2000 annually. The management though is diversifying its activities as it does not want to put all eggs in one basket. It Herman Bastiaenssens, is fully aware that drinking water companies for example tend to take water General Manager softening into their own hands. The last few years, Bayard Europe has taken an interest in wastewater and process water treatment, in water reuse and membrane technology. That was the reason why Bayard Europe became a TNAV-member in the first place. A closer look Unique Selling Proposition: “In the 5 or so years that we have been developing our Bayard provides practical advice, activities in the industrial sector we accumulated quite some develops and designs the solution to experience, especially in process water treatment”, says your problem and warrants a swift Herman Bastiaenssens, the no-nonsense General Manager return on investment of Bayard Europe. “We started carefully, just tackling the easy to solve problems and working on a no cure no pay basis. Sometimes we helped the customer to save energy, or time, or money, or all of these three…. Slowly we became the preferred partner to quite some of these customers. But we are still learning and will not accept an assignment when we are not absolutely sure we can actually deliver. So even if we can cope, for example with the design and engineering of very ambitious water treatment installations, we are happy to leave this part of the market to the bigger TNAV-members, at least for the time being (smiles).” The company decided to focus on interesting niches and so far does not deplore to have made this choice. “Currently we have more than enough on our hands”, Bastiaenssens says, “but as in any other business it is necessary to look ahead.” As a company specialised in water purification and water softeners, it shouldn’t come as a surprise that Bayard turned to reverse osmosis (RO). “We have become sole representatives for Belgium and Luxemburg of Herco membranes, made in Germany. We install the RO-purification systems, whereas the construction part of the work is outsourced”. Last year, Bayard installed about 90 ROs. Among its customers we find Gent and Leuven University. 14 In Leuven one of the ROs purifies the water Reverse osmosis (RO) is a separation process of basins where fish are grown to be used in that uses pressure to force a solution through DNA-testings. It is a good example of how the a membrane that retains the solute on one company customises RO-installations in order to side and allows the pure solvent to pass to the provide the effluent best meeting the client’s other side. More formally, it is the process of specific needs. forcing a solvent from a region of high solute “We are certainly not the only ones to pretend concentration through a membrane to a region that we are typical problem solvers, but this is of low solute concentration by applying a exactly what we are doing” Bastiaenssens pressure in excess of the osmotic pressure. This comments. is the reverse of the normal osmosis process, A customer had a double-sided stainless centriwhich is the natural movement of solvent from fuge that suffered corrosion. “The corrosion was an area of low solute concentration, through a really bad” , says Bastiaenssens, “the centrifuge membrane, to an area of high solute concentrahad to be replaced year after year at an extra antion when no external pressure is applied. The nual cost of EUR 9800. Our analysis provided the membrane here is semipermeable, meaning it answer: the corrosion was due to carbonic acid allows the passage of solvent but not of solute. and too high a pH level. The solution was to Although reverse osmosis seems like a complex provide a duplex softener, RO-installation, system, it is really a simple and straightforward holding tanks equipped with pumps and a water filtration process plate-cooler”. At start-up, steam is propulsed to the centrifuge. The condensate returns to the holding tank. When the water level is low, the steam generator will automatically be filled up with water from the holding tank. The cooling water is pumped into the centrifuge and once its temperature reaches 65° C, it is driven to the holding tank via the plate-cooler. Bayard also earned itself a reputation in carwash systems where the effluent treated with RO is used for the last phase rinsing water. It looks as if this is the right answer to rigorous wastewater quality regulations in this area of activity. Interesting customers are also to be found in the food industry. A farmer, growing organic poultry and eggs, wanted to diversify and to start growing hops, rhubarb and beetroot. Unfortunately, his well water contained an extremely complex combination of iron with organic material. “We accepted to look into it”, says Bastiaenssens, “again on a no cure, no pay basis, and it took us 23 days before we found the right configuration whereby the RO could effectively be used”. The farmer’s installation now uses strictly controlled quantities of chlorine and is equipped with tanks, a juraperl filter, a sand filter and an activated carbon filter. Sure, the solution was not the cheapest, but the water is of the best possible quality, the system works, and the farmer can be confident that his investment will pay itself back in less than two years. This is the type of achievement on which Bayard Europe is thriving. The last few years it has been extending its activities, mainly through word of mouth marketing.

BESIX Sanotec, a full subsidiary of the BESIX Group, profiles itself as an EPC (Engineering, Procurement, Construction) Contractor in the water sector, and more particularly in the treatment of municipal and industrial waste water and sewage, and in water production. Whereas the 1998 sales amounted to some EUR 500,000, the participation of BESIX Sanotec in ambitious water related programmes in the Paul Callebaut, United Arab Emirates delivered sales of up to EUR 22 million in 2007. Today, General Manager the company employs about 50 people. For the civil and building works, BESIX Sanotec can rely on the BESIX group, a large multinational construction company, lately developed into a multi service group, with operations in many countries around the globe. The electromechanical part of the installation is in good hands with BESIX Sanotec. A closer look BESIX Sanotec is understandably proud of its progressively ever more impressive achievements in the Middle East. “85 % of the company revenue is currently created in the Emirates”, says Paul Callebaut, General Manager. With some EUR 300 million of offerings mostly for projects in the Middle East, BESIX Sanotec closed the year 2007 with an order book of EUR 140 million. On the other hand, BESIX Sanotec fully benefits from the synergies with Six Construct, a BESIX subsidiary in the Gulf region. BESIX Sanotec saw a market niche to be taken in EPC-projects for medium-sized water desalination and wastewater purification plants. BESIX Sanotec has its offices in the brand new office block of BESIX in Brussels. In the entrance hall we cannot help noticing a giant poster with the Burj Dubai-tower, currently, with its 800 metres, the highest building in the world. Built by an association of three construction companies including BESIX, the project kind of symbolises the high aspirations of the BESIX Group and to a certain extent also those of BESIX Sanotec In the Emirate of Sharjah BESIX Sanotec in partnership with Six Construct won the turnkey contract related to the extension (Phase VII) of the sewage treatment plant of Sharjah-city. The customer apparently had taken the company in high esteem after it had delivered the earlier phases of the project. The extended water treatment plant will have to cope with an additional 80,000 cubic metres of effluent a day (500,000 P.E). 17 End 2007, BESIX Sanotec won the huge project of Jumeirah Golf Estates, in the Emirate of Dubai, in partnership with Six Construct and Dégremont. It represents a treatment capacity of 220,000 cubic metres a day (900,000 P.E); the fully treated effluent will be reused for irrigation. No wonder in a region such as the Arab peninsula where one litre of potable water costs as much as one litre of petrol in Europe. This plant will be the biggest in the world and will be using MBR (Membrane Biological Reactor) technology. After delivery of the project, the company will also act as O&M (Operation and Maintenance) contractor for ten years. Unique Selling Proposition: Even if overseas markets are a major focus, BESIX Sanotec A company with important internamaintains a solid anchoring on its national market. “We tional expertise making pragmatic have built a dozen major WWTPs for Aquafin in Belgium”, use of available technologies in Paul Callebaut explains, “now this part of the market will be order to best serve the customer. saturated sooner or later, especially for a company like ours which is basically a general contractor, rather than a technology provider. That’s why we are now concentrating on industries, especially the chemical, petrochemical and pharmaceutical sector. In these industries there is a growing need for sustainable water use and reuse”. Recent industry customers include Pfizer, Ineos Phenol, Monsanto, Janssen Pharmaceutica and the Belgian Refining Company (BRC) in Antwerp. For additional growth, the company turns to countries such as France and the Benelux and, outside Europe, also to Northern Africa, from Morocco to Egypt. The strategy is simple: BESIX Sanotec wants to benefit to the maximum from the local presence of BESIX. Solid experience, an elaborate commercial network and technical support from its internationally known partners in the construction sector are some of the main assets of BESIX Sanotec. Technologies We have it from the horse’s mouth: BESIX Sanotec is a general contractor, not a �mere’ technology provider. However, the company does not shy away from the newest technologies.

With a workforce of 40, of whom 6 are working in Poland, the company’s turnover amounted to EUR 10 million in 2007. A closer look Rikie Seynaeve, project engineer In a not too distant past, Desotec focused on wastewater and sludge treatment. After a while, however, the company found itself a lucrative niche called �activated carbon’. As a true niche player Desotec has no competitors within TNAV (and is not too worried about the competitors outside our network either) and this was certainly helpful. Progressively, Desotec expanded its activities and began to sell or rent its products and services not only in its home base but also in neighbouring countries and later also in countries like Spain and Poland. “The activities of Desotec are threefold”, Rikie Seynaeve, the company’s project engineer explains. “First, we take care of the production and delivery of activated carbon. Desotec’s capability and readiness to offer our customers the most suitable type of activated carbon for any application might very well be our unique selling proposition”. In order to meet all customers’ demands, the company constantly develops new products and has acquired five warehouses throughout Europe, to ensure swift delivery at any time. Seynaeve goes on: “Second: almost naturally, and at a very early stage, we started designing and renting activated carbon-based filters. For the treatment of liquids and gases the company develops and builds tailor-made filters”. Another particular feature is Desotec’s impressive fleet of “Another particular feature is mobile filters, the largest in Europe. “For many customers Desotec’s impressive fleet of mobile renting a filter from Desotec is the most comfortable and filters, the largest in Europe. For least expensive solution,” Seynaeve asserts. many customers renting a filter from Desotec is the most comfort“Third, we make sure that the spent carbon is returned to us able and least expensive solution”. so that we can reactivate it.” This has proved to be very suc20 cessful, and it is our contribution to sustainability. To a large extent, Desotec owes its success to its thorough understanding of the business and to the quality of services offered. Perhaps the most conspicuous is the return of spent activated carbon. Desotec has the necessary permits for this type of activity as well as for the international transport of the materials if required. The company built a state-of-the-art reactivation facility at Roeselare, its homebase, especially for this purpose. Activated carbon is a microporous and inert carbon with a large internal surface area (up to 1500m²/gramme). This surface area is capable of adsorbing organic molecules from liquids and gases: the contaminated molecules adhere to this surface The carbon (coal-based, coconut shellbased, wood-based etc.) is activated in three steps: 1.The water is removed (dehydration) 2.The organic matter is converted into elementary carbon (carbonisation) and non-carbon elements are discarded; 3.The tar is burnt off and the pores are extended (the latter process is actually the �activation’ part). Technologies Desotec offers efficient and sustainable solutions for all your water and air treatment applications. Its mobile activated carbon filters, such as the Mobicon®, have proved to be immensely successful and are one of the company’s main assets. Available on a rental base, without investment cost and applicable anywhere, the mobile container can be used on-site in any application such as tertiary water purification, water recycling, groundwater sanitation, treatment of leachate…. Once the activated carbon is saturated, the entire Mobicon® is replaced by another unit, filled with new activated carbon. This eliminates the need for spent activated carbon disposal by the customer. Besides the standard packages, Desotec’s engineering services design and manufacture tailor-made activated carbon adsorbers for liquids (Filtrafix®-L). They also offer advice and engineering services for the development and construction of fixed activated carbon air filters (Filtrafix®-A), and mobile activated carbon filters for air treatment (Aircon®) are available on rental base. Services Services include strong logistics, a huge stock of the most common types of activated carbon, a company lab for testing and quality-control, etc. For the replacement of small quantities of activated carbon, the company offers a full service. Its vacuum truck comes along to empty fixed filters and after that, it takes care of the refill. Fast and efficient. What more could one want ? Another Desotec showpiece is OXYCON®, an aerated activated carbon filter-system. The Oxycon®-system is based “At the latest IFEST environmental technology fair in Gent, we offered our visitors French fries, made on the spot. It was a tremendous success. And people wondered why we could do this completely odour-free. It was evidence of the efficiency of activated carbon in adsorbing unwanted odours.” 21 on the efficient aeration of activated carbon filters, used in wastewater treatment. In addition to adsorption processes, the chemical and biological oxidation of contaminants is stimulated. The system considerably increases the lifetime of the carbon filter and improves the reduction of recalcitrant, non bio-degradable molecules. Unique selling proposition: Our capability and readiness to offer our customers the most suitable type of activated carbon for any application.”. VOC3PLUS® Last, but certainly not least, the VOC3PLUS®-technology for air treatment applications has been developed to reactivate periodically the activated carbon in a compartmentalized air filtration unit (regeneration in situ). This technique is a combination of the Desotec air filtration units with a small after burner unit, and combines 1) adsorption 2) desorption and 3) an autothermic catalytic oxidation of the VOC. That is why this technology is called “VOC-3-PLUS”. Activated carbon is used in water and liquid applications ranging from municipal drinking water treatment (taste, odour and micro pollutant removal e.g. pesticides, …), to domestic water treatment (in-line and cartridge filters), process water (de-chlorination and de-ozonisation), groundwater remediation, and wastewater treatment – tertiary treatment (trace organics and COD-removal, deodourisation and decolourisation, powdered as bio-flock improvement in an aerobic or anaerobic biological wastewater treatment plant, as an additive for physical-chemical treatments), raw material purification (purification of oils and fats, alcoholic and softdrinks, dyestuffs, …), decolourisation of sugar and glucose, food, chemicals, pharmaceuticals) and catalytic processes.

Today, over 30 highly skilled scientists and engineers are working for Ecodis, a number that is expected to double in the near future, now that the company has also started operations in the Netherlands and in the U.K. Ecodis is listed on the Alternext Brussels Stock Exchange. Revenues in 2007 were only € 800,000, but by 2010 should be around € 22 million. The long-awaited certification of the technology by the Flanders Ministry of Health, now very imminent , will probably act as a catalyst. By the year 2011, Ecodis is expected to become profitable. Elmar Peters, founder & General Manager of Ecodis. A closer look The ecodis® system sure is a remarkable invention. The disinfecting cell of the Ecodis® contains specially coated permanent electrodes. A direct current with at a low voltage level sees to it that oxygen and chlorine radicals are formed from the water resulting in immediate disinfection. It destroys the bacteria, viruses, algae and micro-organisms in the water, without the addition of chemicals and without radiation. Additionally, hardly any undesirable trihalomethanes are produced. Harmful components such as cyanides, ammonia and humic acids are oxidised to their maximum. The system meets the rigorous European health and safety standards and guarantees a long operating life. “I started doing research at home in my gaPractical tests show that the disinfecting power rage back in 1997. At the time, UV-technology of the ecodis® is much higher than that of the was on the rise, but I preferred electrolysis. same disinfectant level using NaOCl (bleach or In traditional cleaning techniques salt is used, bleaching agents). but that is a nuisance as saline water should From an economic perspective, the ecodis® not be drained. So I looked for a different contributes to an efficient solution with regard solution and contacted PIDPA, the company to water hygiene. No losses occur, as the oxidants providing my home with drinking water. They are produced directly in the water. The use of were interested and followed my work with electric current per m³ of water to be treated is growing enthusiasm.“ very low (typically 20 - 50 Watt per m³ of treated Elmar Peters in �Forward’, Feb. 2008 water). The use of permanent, long-lasting electrodes also contributes to low operational costs. 23 Potential customers: 1)industries wanting to decontaminate their water mains, to combat legionella in their sanitary installations, to disinfect their pre-treated wastewater and treat their industrial cooling and process water. 2)Ecodis is also extremely efficient in preventing the formation of biofilm, or in physically breaking down biofilm in water pipes of homes for the elderly or hospitals. Biofilm is potentially dangerous as it provides shelter to micro-organisms. In addition, the presence of nutrients can induce an explosive growth. Legionella pneumophila (the originator of the highly feared legionnaires’ disease) is, besides many other micro-organisms, a typical resident of biofilm. 3)Individuals wishing water treatment for their swimming-pool and who want to avoid the use of chlorine. Needless to say the verification of the efficiency Unique selling proposition: Disinfecting with of the ecodis® solution in its various forms is ecodis® is extremely efficient, environmentcrucial to Ecodis. friendly and is not harmful to your health. For more than 10 years now, Ecodis has had the results of its research double-checked by the research centres of the Universities of Gent and Leuven, and other water-related knowledge centres. In Lyon (France) legionella-expert Prof. Etienne has studied the ecodis® solution and in Holland the KIWA has also ascertained Ecodis’ major progress and achievements in the field of wastewater disinfection. The Belgian Red Cross is one of Ecodis’ customers: the Red Cross fills the plastic waterbags they provide in emergency situations with drinking water treated with Ecodis. Product differentiation is part of Ecodis’ business strategy but the company will not really prioritize biofilm breakdown in hospitals or swimming pool water treatment. They are both equally important. As far as legionella prevention is concerned, the company wants to expand its activities from the Benelux countries to include the British and French markets. Installations will be equipped with an online monitoring system, informing Ecodis whether an installation is working properly and whether the water is safe. It is part of the after sales the company wants to provide to its customers. Technologies - The ecodis® mobile unit is effective whenever a legionella or other micro-organism breakout has taken place. The mobile unit allows for on-the-spot decontamination as long as required. The followup then takes place through on-line measurements and/or analysis in certified labs. Performing pilot tests, either semi- or full-scale, for customer-specific problems for all cycles where the microbiology may adversely affect an efficient exploitation, or where oxidizing the problem substances, which are present, may offer a solution. 24 Possible applications may include: Food industry and food packaging industry Breweries Dairy Cooling machines in general Disinfection of waterflows for membrane technologies All applications of the ecodis® mobile can be supervised and adjusted remotely through data-logging and on-line monitoring. This is a valuable tool for carefully documenting the performed tests. - The ecodis® cell: long-term disinfection The ecodis® cell sees to a preventive (drinking)-water decontamination and keeps sanitary and industrial installations germ-free. The size of the cell is variable and determined after a custom audit in combination with data-logging the waterflow. A permanent installation often follows a performed decontamination or a test with an ecodis® mobile unit. The ecodis® can be applied to drinking water, rainwater, process-water, wastewater, swimming and cooling water. - The ecodis® comfort + service plan The ecodis® comfort and service plan has as its objective a significant reduction of operational costs. With a permanent check from the Ecodis office (via modem), the company monitors the functioning of the customer’s ecodis® and manages the production of free oxidants by remote control.

The company, centrally located in the province of Vlaams-Brabant, not far from Brussels, is a turnkey contractor for water-, sludge-, air-, and wastewater treatment technologies and has built Enprotech’s Hans van for over 2 million P.E. for all types of industries. Soest & Marc Feyaerts This is a typically Flemish SME, meaning that it is small, with minimal overhead, flexible, preferring a hands-on approach, is open to innovation and seeking carefully prepared expansion, at home and, why not ?, abroad. I should add: it owes its excellent performance to a limited workforce of 20 hard working, highly skilled and experienced people. 2008 sales are estimated to reach EUR 7 million. A closer look Enprotech provides the overall design, a pilot installation if required, the engineering, the electromechanical aspects of the wastewater treatment plant, the piping systems, pumps and valves. But there is more: “After delivery we like to assume responsibility for the technical follow-up and operation and maintenance. Many of our clients in industry like it that way and it kind of reassures them. Furthermore, this involvement is not only rewarding in terms of business, but above all, it is an excellent opportunity to learn and to increase our awareness and knowledge of the total treatment process. This helps us in becoming an even better and ever more efficient company. We have learned a lot from these activities and we feel that we are well placed to advise companies on how to reduce energy or sludge treatment costs , says Marc Feyaerts, Process and Sales Manager with Enprotech. Hans van Soest, General Manager nods: “Our Unique selling proposition: We go for the (potential) customers usually think of a water simplest solution that best suits the customer. treatment installation in terms of an important investment, which it certainly is. But they tend to underestimate the operational cost, once the installation has been commissioned: over the years I have seen quite some companies overspending literally two, three thousand EUR a day, on energy-consumption and use of chemical additives that could have been avoided.” 27 Soaring energy prices also have an important impact on our business. When wastewater installations provide renewable energy out of sludge and with the system of renewable energy certificates as we know it over here, we believe that owners can expect an interesting ROI. But it is of vital importance to choose the right technology and to reduce operational cost: we as technology providers can help our customers in saving lots of money. Problem solving has made us a better, more innovative company. Even as a rather small SME we have our own Research and Development, of course focused on specific issues and problems we , or rather our customers are facing. Our experience is paying off now: it happens that companies contact us for urgent assistance because the building company in charge of the water treatment project got itself into problems and basically could not manage the problem. We then will do whatever possible to stand by our reputation as problem solvers and manage to finish the job successfully within the required deadline. A recent example: Holliday Pigments (HP) in Comines (on the French side of the border between Belgium and France), leading supplier of ultramarine and manganese violet pigments. The French company that got the assignment for the construction of a physical-chemical installation for HP was not able to deliver, because it made the wrong choices. Quite frequently, contractors will prefer a sophisticated installation, whereas customers most of the time can do with a cheaper, more efficient and less expensive alternative. The importance of correct process choice and technical choices can hardly be overestimated. Enprotech prefers the KISS-approach, “Keep it simple and stupid. It is important to find the simplest solution that best suits the customer”, Van Soest says. “Big companies now approach us and ask us to deal with their problems, companies that only a few years ago wouldn’t have worked with us because we are small, and they would not believe we could provide them with adequate solutions for their problems. Progressively, however, this perception has changed: potential customers see our growing reference list, and they see the sheer size of the projects we are involved in and the complexity of the problems solved by us”. So, Enprotech is doing well and after a successful first with a WWTP delivered at La Réunion, the French overseas territory in the Indian Ocean, the company has acquired a taste for distant shores and is aware of the many opportunities in the emerging countries. However, the company clearly prefers slow growth to being overdependent on borrowed money. “Why should we hurry ?” , Hans van Soest wonders, “as things stand today, we are more than busy right here in Belgium and its neighbours. But in business it is always wise to keep your options open.” Technologies As a typical solution-provider, Enprotech will never promote one specific technology. It uses the technologies and processes that best meet the real needs of the customer. Over the years though, Enprotech has acquired an impressive experience in the following technologies: - Pretreatment: neutralisation, settling, filtration, buffering. Enprotech promises decreased operational and investment costs, through a simplified treatment process providing increased stability and reliability, based on lab or pilot scale tests. - Physical-chemical treatment: coagulation, neutralisation, precipitation detoxication, floculation, sedimentation, flotation, oxidation, adsorption: separately controlled process steps and a correct technical choice based on test results. - Membrane technology, biomembrane reactors: compact, efficient, economical, advanced treatment. 28 - - - - Requiring no settling tank, nor sludge recycling, or sludge “We have learned a lot from operaraking bridge, these compact reactors ((3-5 times smaller tions & maintenance and we feel volume) are suited for water reuse, provide better effluent that we are well-placed to advise quality and lower sludge production, whereas the memcompanies on how to reduce enbranes have a considerable lifetime. ergy or sludge treatment costs.” Water reuse: ultrafiltration, reverse osmosis Aerobic processes: effective for both industrial and municipal wastewaters; biological denitrification and phosphorus removal, surface water quality , effluent reuse Anaerobic processes (wastewater and organic waste): compact installation, stable and simple, biogas production for electrical and thermic co-generation, highly productive at no extra energy cost, with a low sludge production.

Geo-engineering, the subsidiary which is of prime concern to us, it being the TNAV-member, employs about 10 and in 2007, its sales amounted to €12.5 million. Its specialty: mobile containers equipped with a complete MBR-reactor with a capacity varying from 1 to 10 cubic metres/hour. Tony Borgmans, General Manager A closer look “We welcome both small and bigger companies looking for a solution for their process water and wastewater problems”, says Tony Borgmans, CEO and owner of Geo-engineering. “We are currently competing for three tenders for wastewater treatment plants. Of course, the more important assignments are more rewarding. At present we are building a WWTP at Tervuren (in the wider Brussels area), with a 11,000 p.e. that will have to be delivered towards the end of this year”. Geo-engineering does not want to focus on specific market segments. The company has gained the necessary experience in, for example, wastewater treatment for breweries, textile factories, laundries and dumping grounds (for percolate water treatment). The company based at Dessel, north of Antwerp (before the end of 2008, Geo-engineering will move to Geel, just a few miles from there) will not shy away from challenges which are quite out of the ordinary. Geo-engineering has been asked to take care of the wastewater produced by some 3000 EU-officials in the brand new Covent Garden office building in downtown Brussels. The customer, the European Commission, wants the treated wastewater to be reused. A service Geo-engineering was only too happy to provide by means of a so-called ecomachine or ecological wastewater treatment system. In the underground car park Geo-Engineering has built settling ponds, and larger ponds filled with all types of aquatic plant life. A number of Kubota plate-membranes will be finishing the job. “It’s a nice showpiece, and we were happy to contribute to meeting this challenge”, says Unique selling proposition: Borgmans, “but from the start, back in the year “Our mobile containers equipped with a 2000, we believed we would have to diversify compact MBR can either be rented or bought our activities That is why we focus on all types and can handle from one to ten cubic metres of water treatment technologies.” of effluent in one hour” 30 Technologies The Geo-groep success story started with Hydrostab®, a mixture of wastewater treatment sludge, polluted sands, fly ash and water glass (natrium silicate) which has proved to be very effective in covering waste disposals and brownfields. This mixture, some sort of artificial clay, is as efficient as natural clay but allows for a really sustainable use of waste material for which it is hard to find an alternative application. The process has been recognized as being a useful application of waste by the Belgian environmental authorities. Their counterparts from countries like France, Britain and Hungary also have shown interest. In 2002 the Geo-groep entered into a new development phase. Its subsidiary Geo-Milieu West (“Geo Environment West”) started operating a huge sewage sludge incinerator in Bruges (in the West of Belgium). About 100,000 tons of sewage sludge are delivered there annually for further processing: the sludge is dewatered, processed in centrifuges, dried and incinerated. The remaining fly-ashes then are mixed with other waste materials at the Antwerp production plant for the artificial clay or Hydrostab®. In the mean time, Geo-engineering has sys“Together with other companies belonging to tematically been developing its skills in water the Geo-groep, Geo-engineering is perfectly treatment at a high pace, and apparently has capable of delivering turnkey water treatment become quite successful in this area. installations”. The company certainly owes part of its success to its obtaining the sole rights for Belgium of the Kubota plate membranes. But Tony Borgmans is a pragmatist and perfectly willing to apply more conventional water treatment techniques, be they big or small: “From 1 to 300,000 p.e”, he says smilingly. “However, even if we do not swear by membrane technology, we can confirm that MBRs can be very practical, their installation is quite simple, they are cost-effective and they do not take much space”. And that is where the mobile container comes in, easily Geo-engineering’s unique selling proposition:. “These mobile containers equipped with a compact MBR are extremely practical. They can be either rented or bought and can handle from one to ten cubic metres of effluent in one hour”, Borgmans explains. “They are quite handy for temporary use and helpful for so-called P-companies (as companies in Belgium are designated when they produce effluents with a heavy environmental impact). We help these companies to comply with wastewater drainage norms. If the mobile MBRs fail to do the job as expected, the customer will owe us nothing “. It certainly looks like an attractive business proposal, wouldn’t you think? “Smaller companies simply cannot afford an environmental, let alone water treatment specialist on their payroll”, says Borgmans.”However, they can rely on Geo–engineering as we monitor the treatment process. Our maintenance people (7/7; 24/24!) will automatically be warned by mobile phone should anything go wrong and they can practically always solve the problem through a very effective remote control system”. Geo-engineering, although the name may suggest otherwise, focuses not just on design and engineering, but will also be taking care of construction, financing and maintenance of installations. Borgmans confirms that Geo-engineering, together with other companies belonging to the Geo-groep, is perfectly capable of delivering turnkey water treatment installations. 31 Selected references 2006 • ILVA, dumping site at Vlierzele (Belgium): percolate water treatment using MBR technology, 80m3/ day) 2008 • De Koninck Breweries Antwerp (Belgium): UASB 15,000 p.e. • Initial Textiles, Laundry facility at Lokeren Belgium): water treatment using MBR technology 6.500 p.e. • Mireille, laundry facility at Heusden-Zolder (Belgium): water treatment using MBR technology 4.000 p.e. • Covent Garden, Office building, Brussels (Belgium) water treatment using MBR technology – water reuse 750 p.e. • Top’s Foods, Olen (Belgium): physical-chemical treatment & Dissolved Air Flotation 7.000 p.e. • Waste water treatment plant at Tervuren (near Brussels), MBR; 14,000 m2 membrane surface • Small water treatment plants at Sint-Laureins & Lummen (both Belgium) , resp. 330 and 220 p.e.

We have to be within easy reach, should a problem arise and in the interest of process optimization. “ As the Belgian office is the service centre for the GWE group as a whole, the workload is increasing now that the company is expanding. GWE recently set up new subsidiary companies in India and China, and the USA and South-America will follow. The company works with local partners and the actual construction work is outsourced to local subcontractors. Areas GWE is working on are: - granular sludge technology: GWE is a partner of a collective research program in this domain, sponsored by IWT (Flanders Agency for the promotion of science and technology in industry with all TNAV core members as partners), - digestion (fermentation) of bio-ethanol and bio-diesel wastes (bench scale), - sludge hydrolysis by thermophilic biological treatment. That GWE wants to be a key partner in the biomass-related industry should not come as a surprise considering its preference for and experience in anaerobic digestion. The biomass industry is a G.W.E.: Compania Licoreria Nicaragua, Alcohol distillery, Flotamet™ 34 window of opportunity, says Pipyn. GWE focuses primarily on waste from bio-ethanol and bio-diesel production: “Over time, bio-refineries will be making literally almost anything from anything: this is really a sustainable use of waste materials, in fact when you put waste to use, it is no longer waste”, says Pipyn. GWE is also focusing on the treatment of organic waste streams (the organic fraction of mixed or residual municipal waste, bio-waste, market and food waste), allowing the company to put its anaerobic expertise to full use. Many South-East Asian customers have already shown interest as the technology provides “We want to see with our own renewable energy, reducing CO2-emissions from fossil eyes how best to implement a solufuel. Several potential partners are eager to be involved in tion and meet the specific needs of the pre-treatment phase (sorting, fractioning of garbage, the customer” removal of metals,…). Technologies The range of reactors available from GWE comprises - The Upflow Anaerobic Sludge Blanket Reactor (ANUBIX™ B),. GWE’s “work horse”, medium to high loading rate UASB (Upflow Anaerobic Sludge Bed) reactor, with incorporated plate separator, used for most low to medium strength mainly soluble carbohydrate containing effluents. Attained amazing COD removal efficiencies, in some cases up to 99%. The Upflow Anaerobic Contact Reactor (ANUBIX™ C) is a kind of hybrid between a UASB and an Anaerobic Contact Reactor for wastewaters with a moderate suspended solids content such as the ones from fruit and vegetable processing plants for example. - The very high loaded upflow “tower like” EGSB reactor (ANUBIX™ T), working with granular sludge for specific wastewater and space limited sites. - The Mesophilic or Thermophilic Completely Stirred Reactor (ANAMIX™ M and T) with special shredder and mixing device for wastewaters containing a very high amount of suspended solids or for slurries and sludge. - The Anaerobic Filter Reactor (ANAFIX™) using a carrier material for the biomass, e.g. for wastewaters from the fermentation industry, the chemical industry, the pharmaceutical industry, where suboptimal conditions prevail. - The Downflow Anaerobic Contact Reactor with biogas induced flotation (FLOTAMET™) in a proprietary Dissolved Biogas Flotation tank (DBF™ tank) for wastewaters containing significant amounts of fats, oils and greases or with a high salt content. - The High Rate Anaerobic lagoon (COHRAL™) for some applications where space is not an issue. Other products and processes: - Aerobic wastewater treatment: conventional and cascaded activated sludge systems, SBR, ASTEROX™ (a multistage activated sludge system), CYCLOX™ (a continuous SBR), trickling filters, containerised mini-plants, nitrification and denitrification, biological phosphate removal. - Sludge treatment: mechanical thickening and dewatering, sludge drying but also the THEAREX™ process for primary and waste activated sludge (WAS) being a combination of a chemical pre-treatment with a two stage fermentation process. - Agricultural residues: the Rapid Transformation of Organic Residues or RAPTOR™ process being an enzymatic pre-treatment followed by a two stage thermophilic fermentation process. 35 The 1993 movie (and novel) Jurassic Park have been a source of inspiration for GWE’s, as shown by the Thea-rex process for waste activated sludge.Thea –rex of course refers to the Tyrannosaurus Rex or T. Rex. And the Raptor Process (�Rapid Transformation of Organic Residues) is being commercialised by means of a logo showing dinosaurs (�raptor’ is also an informal term to refer to certain dinosaurs). The metaphor makes sense: the monster’s mouth takes care of waste pre-treatment, whereas saliva and stomach juices can be seen as equivalent to the use of enzymes. The stomach also takes care of fermentation and acidogen hydrolysis. Finally, methane gas is generated in the bowels….

Keppel Seghers’ scope of activities includes consultancy, design, engineering, technology developments, construction, operations and maintenance of plants and facilities as well as investments in large environmental projects (DBOO, Design, Build, Own and Operate – DBO, Design, Build, Operate – or BOT, Build, Operate and Transfer and PPP, public private partnerships). The solutions the company offers address a wide spectrum of environmental Werner Van Peteghem, issues such as solid waste, wastewater, drinking and process water, biosolids head Water Division and sludge. Keppel Seghers Belgium, based at Willebroek (half way between Brussels and Antwerp) employs about 110 people and is actively involved in operations throughout the world, especially in the European Union, North-Africa (the Maghreb countries), China and South-America. A closer look Unique selling proposition: The company “Keppel Seghers today combines the best of can provide all technical and management two worlds”, says Werner van Peteghem, head skills needed to successfully complete turnkey of KSBE’s water division. “On the one hand the projects, supply technology packages or hanbetter than average know how of the former dle large investment projects. Belgian company Seghers Better Technology, from which it inherited a solid portfolio and state-of-the-art environmental technologies. On the other hand the vision, the global network and the strong financial resources of the Keppel Corporation”. This combination gives Keppel Seghers a unique position in Belgium. As such it is also different from other TNAV-members and does not focus on typically smaller industrial wastewater projects. Instead, it is actively pursuing contracts for large municipal wastewater treatment plants, with ongoing projects in Doha North, Qatar (United Arab Emirates) (900,000 p.e., a contract with a value of € 711 million) and similar though smaller WWTPs in Ain Beda and Laghouat, Algeria (200,000 and 170,000 p.e. respectively). Keppel Seghers has also built and currently owns and operates Asia’s largest water reuse plant, located in Singapore. The treatment of municipal water, industrial wastewater, seawater, surface and 37 brackish water for re-use as industrial, process and potable water is a growing market segment. With the support of human as well as financial resources of Keppel Corporation, Keppel Seghers not only focuses on water treatment, but also on Waste-to-Energy (WtE) projects, both for municipal and specific industrial solid waste. (WtE, is one solution to actively tackle green house gas emissions and combines waste and energy solutions). Keppel Seghers is also focussing on O&M (Operation and Maintenance) for its large projects. “Operational responsibility and process-assistance are increasingly important”, Van Peteghem comments, “they provide recurrent income whilst contributing to a close relationship with the customer. In large projects such as its Integrated Waste Management Centre in Qatar, scheduled to become operational in 2010, Keppel Seghers is not only charged with design and construction, but also with O&M for a period of 20 years.”. Also in the vast area of water treatment Keppel Seghers favours integrated solutions, from soiled influent to cleaned effluent, sustainable sludge treatment and energy recovery. The above-mentioned Doha North municipal wastewater treatment plant provides reused water for irrigations and sludge treatment for a perios of 10 years. Technologies (Only water and sludge related technologies are mentioned here) - As the first Belgian provider of biological wastewater treatment, Keppel Seghers’ experience dates back as far as 1981, when the first UNITANK® installation was developed. This technology adds the advantages of an SBR (Sequencing Batch reactor)-system to the conventional activated sludge water treatment station. The result is one compact, efficient and continuous biological wastewater treatment plant. Keppel Seghers has over 350 UNITANK® references worlwide. - Advanced water treatment: By adding an extra step to either conventional or cyclic (UNITANK®) activated sludge wastewater treatment, excess nitrogen and phosphorus are removed by specific nitrifying, denitrifying and phosphate accumulating bacteria. This additional treatment can be integrated in the total water treatment solution either during the activated sludge treatment or afterwards as tertiary treatment step. Newater Plant Ulu Pandan, Singapore 38 - Sludge treatment solutions that save energy The company offers solutions varying from biological treatment such as digestion (with or without biogas production and energy recuperation) , composting and sludge cracking to artificial techniques as drying/pelletizing and incineration By recuperating the energy from the treatment of sludge (the inevitable side-product of wastewater treatment) Keppel Seghers’ wastewater plants are capable of running up to 95% energy (fossil fuel)-independent. - Creating new sources of water AzuRO™ is the brand name for Keppel Seghers’ combined and extended (tertiary) water treatment technologies for water re-use. The combination of microfiltration/ ultrafiltration with reverse osmosis and UV-disinfection allows for wastewater to be upgraded to meet the most quality demanding needs. “With the financial backup of Keppel Corporation and its vast experience and advanced environmental technologies, Keppel Seghers Belgium is set to grow to become one of the leading players offering solutions for water, sludge, solid waste and energy”. - Combined biological and membrane treatment Keppel Seghers’ proprietary UNIBRANE® Membrane Bioreactor technology combines an activated sludge treatmernt with highly efficient separation by ultra-filtration or micro-filtration membranes. It offers an extremely performing MBR-system in terms of effluent quality, low capital and operation costs and small footprint. The UNIBRANE® can be applied for both industrial and municipal wastewaters. By adding a Reverse Osmosis (RO) option the treated water can easily be further purified for industrial processes and potable use. - Desalination Together with TNO and six industrial partners, Keppel Seghers has developed a membrane-based distillation concept called MEMSTILL®, a technology that offers a much more economic alternative to the existing desalination technologies for seawater and brackish water. It uses low-grade waste steam and heat of power stations, refuse incineration plants etc. to produce desalinated water using a membrane barrier.

Metis is an acronym for �Milieu’ (Environment), �Engineering’, �Technology’, �Innovation’ and �Service’. Companies offering all this cannot but succeed! With a workforce of ten and with an annual turnover of EU 2,5 million in 2007, the company specialised in wastewater and air treatment. Created in 1993, it joined the Benvitec (Belgian Environmental Technology-group) in Erwin Berghmans, 2002. Managing Director Benvitec’s acquisition of Metis made sense. Whereas the member companies of the Benvitec Group focus on activities such as soil protection, piping, sprinkler installations and plastic storage tanks, the new partner was a specialist in wastewater and air treatment and this allowed Benvitec to develop a number of profitable synergies. Benvitec employs more than 130 and expects 2008 sales of approximately EUR 30 million. A closer look To be sure, �small is beautiful’, the well-known piece of advice by E.F. Schumacher, the British economist, was not lost on the Metis people. The company, however, has been and still is growing, it is gaining experience, and prefers to invest in lasting customer relationships based on mutual trust. These last few years, the company has undeniably found a place of its own in the competitive arena of water and sludge treatment. Its limited overhead allows Metis to operate cost-effectively and to be very competitive. At the same time and whenever this seems necessary, Metis can always count on helping hands from the other Benvitec partners. The chemical industry has become an important customer of Metis, but lately, the company has also been focusing on the concrete sector. The latter is known to need large amounts of water for Unique selling proposition: the concrete production as such, for the treatThe flexible service the company can offer its ment of silex-panels requiring high-pressure customers and the creative application and aqueous cleaning systems and finally for the combination of different technologies by cleansing of installations. These wastewaters Metis are quite remarkable. contain cement particles, sand and all kinds of 41 dyes making their treatment difficult. Far too often, this means that these waters are hardly treated. The wastewater is only allowed to pass slowly through large primary clarifiers or sedimentation tanks. These tanks should be emptied regularly: a labour-intensive and therefore costly job. Customers these days are fully aware that water consumption and drainage costs should be reduced. That’s where the Metis filter press container comes in, dividing the waste stream, a mixture of water and masonry or cement particles, into different and useful raw materials: the water can be reused as process water and the residues can usually be redirected to the production of concrete. Even when reuse is not possible, the method is cost-effective and will help the customer to reduce labour, drainage and dumping costs. The Metis filter press has been built in a mobile container and is fully automated. It is quite simple to handle and operating costs are low. Both residues and water can be reused. It is a simple solution, but that could precisely be the major reason for its success in countries such as Belgium and Germany. Metis is perfectly capable of delivering turnkey projects and to assume full responsibility of projects from design to operations and maintenance. But the company will be happy to revamp or extend existing water treatment installations as well. Although quite busy, Metis does not want to rush things and grow too fast. “For the time being, we prefer to tackle at most 5 to 6 major projects a year,” says Erwin Berghmans, Managing Director of Metis. “When, in addition to that, we manage to bring in a few small-scale projects, in maintenance and/or as subcontractors, we have more than enough to keep us busy. “Maximum customer satisfaction is our absolute priority. We want to make it clear to our customers that their needs come first”, Erwin Berghmans continues. “Their problem is carefully analysed and extensively discussed. Only then will we come forward with a solution compatible with our client’s needs and means. Nor does our responsibility end right after completion. We are always available for maintenance and for all kinds of advice and prepared to provide solutions for ad hoc problems.” As things stand, Metis finds its share of challenging projects in Belgium and is not actively looking for projects abroad as yet. It is perfectly willing, however, to contribute to projects in third countries as a subcontractor, should such opportunities present themselves. Technologies Among the technologies in which Metis has gained more than average expertise, we mention: - Mechanical separation techniques - Physical & chemical treatment - Flocculation, settling, dissolved Air Flotation, oil-water “We carefully analyse and extenseparation. sively discuss the problems our - Vacuum evaporation clients want to see solved.

Over the years the company gained itself an enviable reputation in all sorts of wastewater and water reuse related activities, from manure treatment to the prevention of legionnaire’s disease. Through its activities in wastewater management and particularly manure treatment, Trevi has developed an interest in biogas production, a Stefaan Deboosere, promising niche in these times of soaring energy prices and greenhouse General Manager effects. The company is one of the co-founders of BiogasTec nv, actively involved in R&D, advice, management and construction of biogas-related projects.

It is an ambitious project worth several million EUR. Technologies Industrial wastewater treatment with minimal operating costs: Trevi has more than 150 references of industrial wastewater treatment plants in all sectors. Both the use of fine bubble aeration (Messner) and Trevi’s many years of experience explain why these plants use considerably less electrical power and produce 50 to 70 % less sludge than average facilities. Trevi: Biological water treatment 45 Manure treatment Towards the end of 2008, Trevi expects it will have designed and built up to 50 manure treatment installations (some with a capacity of more than 200,000 m3/year) and doing so, will have become an undisputed market leader. “The undeniable success of Trevi is largely due to the company’s customized approach of problems in the area of water treatment, water reuse and manure treatment”. Trevi developed a manure treating system that starts with separating the solid fraction from the liquid fraction. The latter is treated in a biological plant and contains only 10 to 15 % of the original amount of nutrients. As a result of this, considerably more biological effluent can be spread on farmland (100-150 tonnes/ha) than would be the case with raw manure. Trevi has also developed a system for discharge in surface water. A patented solution for the hygienisation of manure, in which the solid fraction is transformed to a substance, consisting for 90% of dry matter, adds up to the list of achievements. This development allows for the reduction of the volume to be transported by 80 %. In the automotive industry, Trevi introduced new ways to minimize the use of water and raw materials: - until recently, deionized water was used in the wetting sanding lines and polluted with small paint particles, discharged to the physical-chemical wastewater treatment plant. It is now collected and separately treated in a recuperation unit (continuously operating sand filters, microfiltration and UVdisinfection) from where it is recycled into the production process as water supply for the humidification of the spraybooths. - Trevi developed a process to close the loop in the phosphate line. Rinsing water from the phosphate bath, containing high amounts of nutrient and heavy metals, is treated by a reversed osmosis plant in two steps, operated at different pH values to avoid membrane fouling. Permeate is recycled to the rinsing bath; concentrate is partly reused to compensate evaporation losses in the phosphate bath. Other areas of experience include legionella control and groundwater treatment.

A closer look VWS Belgium, formerly known as IBTV (itself a merger of IBT and US-Filter), is a small but ambitious subsidiary of Veolia Water in France, itself one of the four divisions of Veolia Environnement (formerly Vivendi Environnement (until 1999 called Compagnie Générale des Eaux) . This environmental technologies group is a large multinational company employing more than 298,000 , with operations in 64 countries and a revenue of € 28.6 billion in 2006. Unique selling proposition: “We are really lucky that henceforth we can It took the sheer strength and the financial combine the flexibility of an SME with the and technological resources of the Paris –based power, the resources and experience of a truly mother company for what came to be called global company.” VWS Belgium to find a second breath. Veolia Water headed the consortium that would obtain the contract for the design, construction, financing and operation of the Brussels North wastewater treatment plant for a period of 20 years. It was the biggest public private partnership (PPP) contract ever in the water sector in Belgium. The huge plant was not even fully operational when, in 2007, VWS started looking for new challenges. In order to strengthen its position on the Belgian market it acquired See:Water, a small company from the borough of Tremelo (not far from Leuven), with a considerable expertise in 49 membrane technology and MBRs. The acquisition of See:Water was an indication that VWS-Belgium wanted its share of the Flanders market as well, and at the same time added membrane technology and MBRs to its range of technologies. “We are really lucky that henceforth we can combine the flexibility of the SME with the power, the resources and experience of a multinational company”, says Kris Lambert, General Manager of what used to be See: Water, and currently CEO of VWS Belgium: “Veolia does not just want to be the biggest company in its area of activities (right after Suez), but it certainly has the ambition to be the best possible partner”. “Our technological experience is well above average, but unlike some other major international players, we do not develop our own membranes, so we are completely free to decide, together with our customers, on the best solution in their particular case. This might very well be our unique selling proposition,” Lambert continues. “From my See:Water years, I vividly remember that major customers clearly value the creative solutions provided by small companies like ours, but sometimes seemed reluctant to do business with us. Now that we are part of a greater whole, I can see the difference. These very same customers are more willing than ever to work with us. I do not blame them: they know that we are strong and can cope with possible financial problems, delayed payments etc.” Technologies One of VWS’ specialties is ultra-pure water, for dialysis units in hospitals and for the pharmaceutical and chemical industry. The company has the full range of technologies and services. Over the years, the mother company has invested heavily in its main Anjou R&D Centre near Paris, and it continues to do so. Veolia Water provides a range of solutions and services to make water treatment as efficient as possible and guarantees up to 30 % more efficient water usage. Veolia offers an extraordinary portfolio of differentiating technologies. Furthermore a whole range of associated services is available on each site to guarantee the technical efficiency and life expectancy of the installed solutions.

VSH is part Marc Handekyn, sales coordinaof the Dutch Volker Wessels group, a leading European building tor & Wim van den Broeck, head company. electromechanical department In over 100 years, the Company has grown together with the development of the cable and pipeline networks in the Netherlands, which provided the basis for its’ present, leading position in the market. The Belgian subsidiary; formerly known as Aquavia, but taken over by VSH back in the nineties, is a growing company employing currently about 400 and with 2007 sales of € 44 million approximately. Originally a specialist in water distribution, it started developing fully integrated water supply-systems, including wastewater main sewerage, sewage systems and water treatment. Sign of the times: these last few years, the focus of V&SH has shifted more and more to environmental solutions and rational energy use. A closer look Unique selling proposition: Ever heard of OCAP ? It is a shining example of VS&H can offer complete solutions to its custhe type of projects V&SH wants to develop. On tomers, a capacity requiring project managethe internet you can read that “OCAP is a joint ment skills above average. venture between the Dutch gas supplier Linde Gas Benelux and [the above-mentioned ] Volker Wessels firm of contractors. It supplies pure CO2 (carbondioxide) to companies cultivating under glass. This CO2 is released during the production of hydrogen at Shell in the Botlek industrial area and would otherwise be expelled into the atmosphere. OCAP supplies this CO2 via an existing pipeline and a new distribution network. This enables horticulturists to save about 95 million cubic metres of natural gas per year. It also reduces CO2 emissions by about 170,000 tons per year. It is therefore a unique form of cooperation, for both the environment and greenhouse horticulture,” (http://www. ocap.nl/Factsheet_UK.pdf). “This is exactly the type of project we have in mind”, confirms Marc Handekyn, sales coordinator with V&SH. Of course, the OCAP project is huge, as it involves some 500 horticulturists. It goes without saying that we are happy to work on smaller-scale projects just as well. We think, and so do the local 52 authorities, that the heat produced by the industry can be used to heat for example an open air swimming pool. At current prices of natural gas or oil, municipalities simply cannot afford to heat pools, but we can organise a perfect match: by linking plant to pool we solve the problem by putting the heat from the industry to use. We can pipe the heat to the swimming-pool, even if the distance to be covered is easily 2,3 miles or more”. “Look at it this way”, says Wim van den Broeck, recently appointed head of the electromechanical department of V&SH, “One of our strengths is that V&SH basically is a transport company: our pipes, tubes and cable networks transport electricity, water, gas, heat, compressed air, carbon dioxide, you name it. Making connections that really make sense, organising a perfect match between two parties: that is what V&SH is about.” By the way, the installation of swimming-pools still is one of the most successful niches of the company. With considerable succes, Visser & Smit Hanab have developed solutions for water re-use making it easier to maintain the swimming water at the required temperature at less expense. “Recently, we have shifted our focus to complete water solutions. In our search for ways to decrease the cost of operations, we soon realised that all techniques are interrelated. Heating, electricity and water use all need to be optimised,” Van den Broeck adds. Over the years, VS&H has acquired an exceptional know how in the design, building, financing, maintenance and - if the customer so wishes - the operation of both underground and above ground piping and connections for utilities, energy, water, communications and related equipment. Its electromechanical department in particular has developed considerable expertise in the construction of pumping stations, wastewater and sludge treatment, in drinking water purification and swimming pool water technology. The construction of drinking water supply systems and of water treatment installations remains a core business. Even though the company assumes full responsibility for any project (“We want to be a one stop shop for our customers”), and does deliver turnkey solutions, it outsources the masonry work to a reliable partner in the construction business. In this area of activity too, the energetic and environmental aspects are becoming ever more crucial. “It would be foolish, with our considerable expertise, not to go for the important opportunities in this area”, Van den Broeck adds. “So, in December 2007, we piped a cooling water installation, using channel-water for electricity producer SPE in Gent. Together with VMW (a major drinking water company in Flanders), we installed an ultra-filtration unit for Taminco, a chemical plant in the same Gent area, so that it could also use treated channel-water, this time for its process purposes.” Technologies V&SH designs, builds and maintains all projects in the following areas: - wastewater treatment and purification: of both municipal and industrial wastewater and the purification of leachate. - drinking water production: in addition to pumping stations for drinking water distribution, V&SH builds full treatment stations for drinking water treatment or purification. Several water companies are among its most dedicated customers. - sludge treatment: V&SH does not �just’ treat wastewater, but also offers full sludge treatment services. 53 - pumping stations: V&SH designs and builds pumping “We are basically a transport stations for both drinking water and wastewater company: our pipes, tubes and - overground pipes: V&SH has all the know how required cable networks transport electricity, to install all piping, in PVC, HDPE, (stainless) steel, etc. water, gas, heat, compressed air, - process water: VS&H provides all necessary equipment carbon dioxide, you name it. for “grey water” and/or rainwater to be used as process Making connections that really water. make sense, organising a perfect - small-scale wastewater treatment plants: design and match between two parties: that is building small wastewater treatment plants, using reed what V&SH is about.” bed technology, bio rotors, etc… - swimming pool technology: V&SH has all the necessary know how for the construction and maintenance of large public swimming pools. The company also takes care of swimming pool renovation, and can inform you about evolving regulations.

The company employs today over 225 environmental engineers and specialists and has a turnover well beyond € 50 million (2007). Working Willy Gils, COO en Luc Vriens from the heart of Europe, with offices near Brussels and Paris, it has developed an extensive network of local companies and representative CEO Waterleau offices, from Beijing to Riyadh, from Mumbai to Dubai, and in the 8 years of its existence has compiled an enviable track record. A closer look Waterleau was created in 2000 by 5 experienced experts in water and wastewater treatment technology. The company quickly grew to become a Group with worldwide operations and ambitions, offering wide range of solutions in the field of water, wastewater, sludge (not to mention air and solid waste treatment) and waste-to-energy. Over the years, Waterleau has developed strong relationships with multinationals, especially in the brewery and beverages sector and this gave a strong impetus to its geographic expansion. The preferred approach is to establish a joint venture with a strong local partner. Whereas the latter provides its knowledge of the local market and sometimes its own expertise, Waterleau brings its technology and know how to the joint venture. The result is a true win-win situation, beneficial for both partners but even more so for the JV’s customers. One of the reasons of its success is that Waterleau is a true solution provider, integrating, combining, optimising …existing competences. In addition, continuous feedback from projects leads to innovation and improved performance. Waterleau can rightfully claim that it manages to integrate all disciplines, in contrast to research institutes, consultants, contractors or operators. Unique selling proposition: Waterleau, although a larger player by local, Our wide range of proprietary technologies allows us to tackle all water and waste related i.e. Belgian standards, is small on a global level, problems and to provide the economically and compared with for example Veolia, not to menenvironmentally best solutions. tion General Electric or Siemens. “No, there is no reason whatsoever to develop 55 an inferiority complex. From the point of view of technology, we are just as good”, says Willy Gils, chief operating officer, “But experience shows that we are less rigid”. This greater flexibility is of course typical of smaller organisations with a strictly limited overhead”. “Whoever you are, any customer will go where he/she perceives added value”, Willy Gils goes on. “It is up to us to provide it by our mastery of the technologies, by offering a better solution, as compact and simple as possible and we seem to manage”. Waterleau in recent years almost naturally has developed an interest in biomass and bio-energy. Sludge is the end product of biological wastewater treatment and thus a natural by-product of Waterleau’s wastewater treatment technologies. As sludge contains too much water, even after mechanical dewatering, to be used as fuel, it has to be thermally dried. Waterleau has its proprietary technologies available for this purpose. After drying, the sludge has a heating value of about 16Mj/kg and can be considered to be an interesting form of alternative energy. Via its daughter-company Biotim, the group is involved in the Valmass renewable energy project. Biotim provides all the technologies to convert the biomass/biowaste into energy: anaerobic digestion, MBR, softening, RO, sludge dryer. Also through Biotim, Waterleau is strongly present in the Southern (Walloon) part of Belgium with sales amounting to € 10 million. It has designed and built many new wastewater treatment plants (including the completely covered Charleroi showcase) as well as renovation projects to bring existing plants up to European standards on nutrient removal. “Internationally Waterleau and Biotim are fully complementary,” Willy Gils asserts. “Add to this the air treatment track record of Waterleau France – more than 30 years in the business – and you will understand why clients are truly considering us as a one-stop-shop for their water- and wastewater projects.” For years now, Waterleau has been operational in mainland China. The China experience has been and still is of huge importance to Waterleau, as the Chinese are very keen to have the newest in technological developments and have funding available. Two new wastewater treatment plants, were recently delivered in Coloane and Macau. Waterleau’s Macau subsidiary is in charge of longterm operations and maintenance contracts for these plants. In the Shanghai region Waterleau’s 50/50 joint venture company is currently building a household waste incinerator, meant to process 300,000 tons of solid waste per year (a community of some 1 million people), generating 18 MWe. Anaerobic water treatment installation, Sevilla, Spain 56 Waterleau has also started up operations in that other emerging giant, India. In this country Waterleau has entered into a joint venture with Ion Exchange Ltd, the country’s premier company in water and environment management and is involved in several projects. The joint venture will close its previous fiscal year with a turnover of well above 10 million euro. “The company has an appropriate solution for any water problem, not only from a technical or ecological point of view but also by economic standards.” Also the Middle East constitutes an enormous challenge, but the Waterleau people will not easily be intimidated. They are involved in large projects on water reuse in Saudi Arabia (Mecca, Riyadh), the Emirates and Qatar. The African continent is already contributing considerably to Waterleau’s turnover with projects in Ghana, Angola, Congo, Nigeria, Tunesia, Ethiopia,... - The Waterleau LUCAS® system is an advanced development of ordinary biological treatment, using activated sludge (i.e. micro-organisms). LUCAS combines the benefits of conventional water treatment with sequencing batch reactor (SBR)-technology. Over the years, a complete family of LUCAS wastewater treatment systems has been developed, each member showing specific additional features. - With the acquisition in 2004 of the Belgian company BIOTIM (formerly part of the Suez Group), Waterleau inherited important additional expertise in anaerobic wastewater treatment – the BIOTIM® UASB system, becoming a top 3 world player in this field, with more than 200 references. - At the same time Waterleau looks beyond the limited end-of-pipe thinking and switched to a process-integrated approach.

When developing the �Water on the Rocks’ concept, Waterleau’ s CEO Luc Vriens was very much aware of this basic unequality. �Water-on-the-Rocks” is about providing locally produced and absolutely safe drinking water to people in developing countries. The water will be made available in biologically degradable bottles or small containers in the shape of an ice cube, can be enhanced with minerals, nutrients or flavours and should not be transported over distances of more than 1 mile. The project could be funded with the revenue generated by WATERBAR® , another Waterleau concept, focusing trendy markets in the affluent North. It exists in variable sizes: 10, 50 or 100 litres/hour and uses smart cards or coins. Water is consumed almost the same day (�freshly brewed’). and is an alternative to water dispensers, bottled water, soft drinks and tap water.
