Action Item 1b&2
It was agreed that samples from KOTO supplemented with salt would be used for testing. iBET was
to arrange this to be supplied in M11. This was done and samples were sent to Extractis.
It was also agreed that iBET was to arrange delivery from ARAVA
Action Item 3
DCU has selected two membranes from DOW for the RO testing. The membranes are the DOW LCLE4040 and the Dow SW30HRLE-4040.
SW30HR is available at iBET and will be used.
Action Item 4.
It was suggested that we should prepare to seek approval for an extended period of testing. An
outline proposal including justification should be provided.
Action Item 5.
D3.1 is completed
Action Item 6.
Oxidine indicated that in RO system they usually collect (using analog inputs (0-20 or 4-20 Ma)
signals from sensors and a MODBUS communication to PLC):






Flowrate: feed and permeate
Conductivity: feed and permeate
Pressure: pressure after HP pump (membrane inlet) and concentrate (the we calculate P in
membranes)
Recovery and salt rejection are quite simple as they are math calculations.
Temperature
Levels (permeate tank and feed water tank)
DCU indicated that we would need:







feed water from the HRAP effluent pre-treatment to the RO pump:
o pressure, volumetric flowrate, temperature, conductivity – TDS
o ph, TOC
RO Permeate water:
o pressure, flow, conductivity - TDS
RO Brine water before Energy Recovery Device :
o pressure, flowrate, conductivity –TDS
RO Brine water after Energy Recovery Device :
o pressure
RO Differential membrane pressure (to monitor fouling)
Membrane Recovery % (this can be calculated from the flow rate measurements above)
Salt Rejection % (this can also be measured from above conductivity measurements: TDS-feed – TDSproduct)/ (TDS-fee)
B. Progress Review
1. BiboAqua
A layout of the 40’ container has been prepared.
This includes equipment for WP2 and 3. The space for WP is 3038mm by 2270mm (see sketch below
for layout).
The pressure vessel for the RO to be tested at DCU is well in excess of this. Options:

The port to port length of the 3x element pressure vessel is 3429mm from Phoneix Vessel.
This exceeds the length which we are given to work with in the container of 3038mm. The
only solution around this to still achieve the desired 50% recovery would be to have 3
pressure vessels that include only 2 membranes each. This would reduce the port to port
length of the pressure vessel to 2413mm meeting the space requirements. Test on
simulation software have confirm that the operation and performance of RO will not be
affected.
Action 1: Check what specification Bibo-Aqua requires for the design of the RO and when does this
need to be provided.
2. iBET: Pre-treatment
Further results have been obtained from the Photolysis and the Activated Carbon treatment.
The comparison between alternative treatment remains to be performed.
Results only concern samples from KOTO.
Samples from ARAVA have been delayed (new samples have been on the 08/06/2017). Aim to start
testing during Week 3 of M13
Action 2: Provide information to BiBoAqua on footprint of pre-treament system (when available)
and confirm sensing requirement to Oxidine

Extractis Characterisation
Demineralisation tests: Evaluate efficiency of ED reactors for
Extractis demineralisation
Extractis Design pilot scale reactor
Samples sent by iBET were received during the last week of Month 12 and have been
treated.
The characterisation before and after demineralisation during the same week
Supply of further samples was requested from iBET. These will be sent after Week 3 of
Month13
Action 3:
 An argument should be prepared to confirm that ED would only be tested with KOTO rather
than ARAVA and that testing will be done at Extractis so that the objective of WP3 Task 3.2 is
to design the ED system and its operational procedure that would best suit KOTO. It had
been suggested that his would be presented to the Saltgae Management Board for approval.
4. DCU-OMS: Pump Design and RO test rig
OMS and DCU have completed the design changes incorporating results from system modelling, a
hydrodynamic analysis and a structural analysis as well as the material selection. The Quadruplex
pump design is now complete however the design of the valve frame will continue to be analysed.
Design changes which were incorporated in the last version of the pump include:
 Number of small modifications
 A modification of the valve support frame to reduce flow constriction and associated flow
fluctuation and hydraulic losses. A structural model was used to confirm minimal impact on
structural integrity.
 An analysis of overall pump frame dimension to assess feasibility and benefit of a weight
optimisation. A maximum feasible reduction of 1 to 3kg was calculated and structural
changes were deemed un-necessary due to impact on manufacturability
The aim is to compare computational simulations and results with operational observation to inform
further improvement to the design.
OMS and DCU have now commenced the design of Pump/ERD.
5. RISE/DCU Pump Testing
Wear Testing Suggestions:
A number of questions were raised by RISE to OMS and DCU:
 Can a cross-section of the mobile component which contains the rollers be cut out to reveal
corrosion on the micrometre scale? (can it be removed and destroyed)
 Do the pumping chanmbers require desctructive testing since they will be manufactured out
of Super Duplex?
 Proposal to measure abrasion on plungers over region in contact with seals. Was this
accepted by OMS?
 Will he seal block require testing
 Can we get the pump back to our lab after the field operation?
 And in that case, may we perform destructive tests of the pump?
 How much time do we have to perform tests after field operation?
Background information on the last 3 bullet point:
We have had further internal discussions about the wear tests of the pump and we have an outline
for the wear test of the seals, which comprises analysis to investigate changes of surface roughness,
seal thickness, seal weight and material composition of the polymer. These tests only require that
the seals are removed from the pump and sent to us after the field operation, and that we get
some extra unused pieces of seals for initial analysis together with the pump delivery in July.
Concerning the metallic components in contact to salty water the approach depends on if we can get
the pump back after field operation, and whether we can make destructive tests of the components.
Some of the proposed tests require a cross section of the surface which means that the pump would
be disassembled and destroyed.
So our questions are:
Also it had been mentioned that aluminum will be used for any component in the pump.
 Is there aluminum present in the pump? And if it is, which component? It would be
interesting to investigate the corrosion of that part.
Action 4a: RISE to raise these questions with OMS
Action 4b: RISE to prepare proposal to Saltgae Management Board to justify extension of wear test
beyond the end of WP3. This should include an outline of the proposed testing. DCU to
communicate this to Management Board and seek approval.
C. Items for Discussion
1. Communication from KOTO
Conclusions for KOTO demo site are:
Reverse Osmosis (RO) process will be tested at the Slovenia demonstration site.
The RO is being designed to meet the specific requirements of the two site.
Ultrafiltration and nanofiltration as the potentially most effective pretreatment= Nanofiltration
process using the NF270 membrane (achieve the highest organic compound removal).
WW Flow 0.1 m3/h in Slovenia. Due to the low flowrates, it is planned to operate the pump/ERD
system as a batch process.
Further tests will be required to assess the required pressure conditions to achieve optimal technoeconomic performance. Tests will also be needed to account for higher salt content expected in the
final KOTO operations.
We have checked the transport costs from Ljubljana to Dury, France (Extractis) in case that some
desalination tests would be performed at Extractis with few cubic meters of waste water and the
transport costs for 3 IBC (3 m3) would be 500 EUR. A bit higher cost are expected if we would send
the samples to IBET, Portugal.
Please advise about further actions for Slovenia demo and if about the cost distribution for
desalination system (which partner would purchase and supply equipment) and also important
issue, the timing for construction and demonstration.
