Why use ozone?
Ozone (O3) consists of three oxygen atoms and is a gas found
naturally in the air we breathe. It works as nature’s own cleaning
method to keep air and water free of viruses, bacteria and other
harmful microorganisms. During the cleaning process, active
oxygen eliminates contaminants and is broken down into normal
oxygen (O2).
In other words, ozone does not leave behind any chemical
byproducts. Simple, effective and environmentally friendly! The
result is fresh, clean air and water, for breathing and drinking.
Ozone is as easy to introduce to water as it is to air, which
means the cleaning process becomes very effective, not to
mention advantageous in terms of cost savings.
– safe to use in living areas, as well as
for food storage
– low investment and operational costs
– effective, flexible and quick cleaning process
– no byproducts (ozone is broken down into common oxygen)

Ozone Tech Systems
Ozone Tech Systems, started in 1993, offers a wide range of
proprietary ozone generators for cleaning air and water, all
produced in Sweden. In order to ensure the best possible
functionality, we have an in house design and consultation team,
as well as servicing and installation technicians.
We have many good references from a broad range of ozone
use. Our products are used for, restaurant exhausts, cleaning of
exhaust ducts/minimising odours and recycling of heat, as well
as for different kinds of odour problems, such as rotating heat
exchangers for homes, grease traps, garbage rooms, swimming
pools, remediation of toxic environmental waste, etc.
See our website for more information on our products and
ozone use.

“The retting process used in biogas facilities
produces sulphur compounds, such as
hydrogen sulphide and mercaptans, which
smell awful.”
Odour free
biogas facility
Biogas facilities often use manure and meat scraps to
produce biogas. The clean methane gas is then piped
into the natural gas grid, where it is subsequently used
to heat houses and properties.
What is biogas?
Biogas is a mixture containing
primarily methane and carbon dioxide.
The gas is produced when microorganisms break down organic material
in the absence of oxygen. The process
occurs in natural environments and is
one of nature’s ways of breaking down
biomass into smaller constituent parts
for reuse in the cycle of nature.
Ozone – an important part of the
solution
The retting process used in biogas
facilities produces sulphur compounds,
such as hydrogen sulphide and
mercaptans, which smell awful.
High concentration ozone generation is used to solve the problem.
When the clean oxygen is passed
through the discharge field in the
ozone generator a proportion of the
oxygen is transformed into ozone.
The ozone is then introduced into a
long pipe that acts as a reaction
chamber. An exhaust fan sucks out
the foul smelling gasses from the
large receiving tank for manure and
meat scraps and into the pipe. Which
is where the ozone and the gasses
meet. As they travel down the reaction
chamber, the foul smelling gasses are
broken down.
Any remaining molecules that have
not been broken down are caught in
an active charcoal filter. These
molecules are thus further subjected
to ozone molecules, resulting in their
being broken down.
The active charcoal filter also plays
another important role: it breaks down
any remaining ozone into oxygen,
ensuring that there is no ozone leakage
from the chimney.
A second charcoal filter is installed
to clean the air from the reception area
where the lorries unload the raw
materials. The air inside the reception
area is sucked out through the
charcoal filter. This reduces the spread
of bad odours to the surroundings.
What is Ozone?
Ozone, sometimes called active
oxygen, is found in air and its presence
is one of the conditions for life on earth.
Ozone is a very commonly used bactericide all over the world. However, at
the same time the gas, which contains
three oxygen atoms in each molecule,
is also one of the most poisonous ones
imaginable. Which is why it must be
handled with the greatest care.
Ozone in nature
Ozone is produced in the upper
atmospheric layer. It is created in a
photosynthetic reaction between
sunlight and oxygen. The ozone layer is
an important protective one for
humans, as it prevents the levels of
ultraviolet rays from becoming too
high. Lower down the atmosphere,
ozone is produced in conjunction with
thunderstorms. When lighting strikes,
part of the oxygen (O2) in the air is
converted to ozone (O3).
Ozone and fresh air
One can often smell fresh air outdoors
after a thunderstorm. This is due to the
ozone content that our noses can
detect in concentrations of
RECEIVING TANK
approximately 0.03 ppm (parts per
million).
Indoors, ozone levels are normally
lower as it is consumed by contact
with organic material. When they reach
these levels, we normally perceive the
air as stale or ‘dead’.
In accordance with international
regulations, and as decreed by the
Swedish Work Environment Authority,
ozone levels should be less than 0.1
ppm for an eight hours working day.
In the closed system that breaks down
foul odours, as, for example, here at
Laholms Biogas, the ozone level is
significantly higher.
Odours can be removed
Ozone can help break down and
eliminate odours. Each situation needs
to be studied in order to find the right
solution.
