Liquid jet Gas Compressors for Ozonation & Chlorination of Wastewater

Ozone and Chlorine are powerful disinfectants used in wastewater treatment. Once added to water they attack the bacteria and viruses in that water and destroy them.

Ozonation plants generate ozone gas and directly add the ozone gas to water. Alternatively In large Wastewater treatment plants chlorine in gas form is directly added to the wastewater.

For maximum effectiveness it is essential that necessary amount of ozone or chlorine is fed into the wastewater and dispersed evenly into it. To ensure fast dissolution the ozone or chlorine gas is distributed in form of small bubbles in the wastewater.

Achieving micro bubbling is complicated and it involves first pumping chlorine or ozone into the waste-water and then ensuring that the chlorine or ozone splits itself into small bubbles and disperses evenly through the liquid.

Liquid jet Gas Compressors are simple devices that operate on the basis of the jet Venturi principle. When used for ozonation or chlorination, the Liquid jet Gas Compressor uses recirculated wastewater from the tank for operation. The Liquid jet gas Compressor sucks the ozone or chlorine gas through its suction inlet, mixes it with the circulating wastewater and discharges their mixture through its outlet.

The internal mixing process happens rapidly and experiences large shearing force between the ozone / chlorine and wastewater. These shearing forces have the capability of breaking the air volume into fine bubbles.
By carefully designing the Liquid jet gas Compressor’s internal geometry and by regulating the operating pressures it is possible to have an outlet flow comprising of fine ozone or chlorine bubbles dispersed in the wastewater.
It is possible to achieve a min bubble size of 50 µm or 0.05mm through a Liquid jet gas Compressor.

Liquid jet Gas Compressors are best suited for wastewater aeration because of their inherent characteristics.

• Ability to produce a uniform flow of micro gas bubbles dispersed evenly through the liquid.
• Suitable for both batch type and continuous operation.
• Can be manufactured in a large range of materials (Plastics, Stainless Steels, Exotic Materials)– it helps to select the best possible material compatible with the involved chemicals and reduces the risk of corrosion
• Liquid jet Gas Compressors do not contain any moving parts and have large internal passage areas, hence are not vulnerable to liquid entry or clogging by solid particles.
• As they have no moving parts, maintenance requirements are very less. Also it reduces largely the risk of abrupt breakdowns, helps in maintaining the regular production schedule.
