Waste Water Treatment
|
|
O3 Water Systems is backed by the experience and expertise gained from over
25 years of treatment system design and manufacturing.
Our equipment is in use with many full scale waste water treatment systems for water
recovery in fish hatcheries and farms, domestic, municipal and commercial sewer systems,
liquid waste from food processing, and industrial toxic waste. In these applications
ozonation systems provide wide range of support. From assisting in flocculation, foam
fractionation, bio-filtration to direct oxidation where ozone acts directly or in
conjunction with other oxidation to form Hydroxyl radicals. Results required may be
anywhere from just a reduction of biological waste, to a complete purification and
sanitation as required by the drinking water quality standards. Such "safe to
drink" water is often used for irrigation in farming and parks, in secondary plumbing
systems and for complete recycling in an industrial process or a
farm.
This technology offers "gold mine" opportunities in many desert states, where
water sometimes costs more than oil. Instead of facing problems how and where to discharge
the waste water, millions of m3 of water can turn large areas of desert into a
green paradise. The sludge is also disinfected, and in most cases suitable as a natural
fertilizer.

While ozone is the superior and most natural agent for
sanitation and water purification, it is not a miracle cure. For best economy, ozone is
applied in conjunction with a whole chain of other clean and environment friendly
techniques, also supplied from O3 Water Systems.
- Rotating screens for flows from 18 m3/hr. to 460 m3/hr.
(= 80 GPM to 2,025 GPM) with screens 15 microns to 100 microns. About 1% of the main flow
is charged with ozone for continued backwash. The water for backwash does not require any
chemicals, and it does not have to be heated.
- DAF cells are suitable for aeration of waste water with very high
organic content. In this process ozone oxidizes surface of tiny organic particles,
creating tiny bubbles of carbon dioxide. Nitrogen gas from air provides further lift to
the particles. Resulting foam is removed by shimmers.
- Foam fractionators work in a similar way as DAF cells, except they do
not need mechanical shimmers. The foam overflows to a special compartment where it is
removed by a high pressure mist. Ozone is injected into the incoming water line.
- Bio-filters need ozone treated water without pathogens, otherwise the
pathogens may decimate the aerobic colonies of water cleaning bacteria.
- The effluent water from bio-filtration is further purified with ozone
for final purification and sanitation.
- In more elaborate industrial waste water treatment systems ozone is
applied in a pH-LOW tank followed by filtration, pH-HIGH treatment with ozone followed by
filtration, further followed by a high ozone level treatment assisted with hydrogen
peroxide and (or) UV radiation (PEROZONE).
- Ozone also helps in oil separation and sedimentation.
- Aerobic and anaerobic digesters are suitable for pre-treatment, to be
followed by OZONATION.
- OZONATION of large lagoons provide a much more efficient
bio-treatment, and usually including also a final disinfection with ozone.

In most cases, not all of the techniques above need to
be implemented at the same time. For the right selection of proper technologies, many
aspects must be evaluated, such as:
- water flow
- waste water content based on laboratory test results
- space available, and cost of the space
- target water quality [anywhere between just some reduction of BOD (Biological Oxygen
Demand), to the bottled water quality standards].
- penalties for discharge of water with BOD above allowable limits.
- cost of water and estimated value of recycled water.
O3 Water Systems is ready to provide a waste water treatment solution which
meets all requirements in the most economical way.
