Air Blowers:

Air blowers are used in supplying air to the aeration tank in the STPs, they also used to provide air if needed to the equalization tank, lift station, air lift pump, and for air scouring of the media filters. They range from positive displacement types for ranges up to 3000 m3/hr to centrifugal types for larges sizes. They can be equipped for sound enclosure to limit the noise level .

Submersible Aerators:

Self-aspirating submersible aerators for wastewater and water treatment in municipal and industrial plants. Main areas of application are mixing and equalization tanks, activated sludge tanks, SBR-reactors and sludge storage tanks at a water depth between 2 and 9 m (7 - 30 ft).

The aerator is free standing on the bottom of the basin and hence can be installed without emptying the basin.

The aerator is characterized by a very low noise level and no aerosol formation. The aeration produces fine bubbles and the oxygen transfer factor is high.

Venturi Jet Aerator:

Ideal for mixing combined with aeration of wastewater containing sewage, offal, organic industrial effluent, slurry, etc. Also for use in balance tanks where a combination of mixing and aeration reduces septicity and smells. Other uses are in cleaning of storm water tanks. Especially suitable for emergency or intermittent aeration tasks. The venturi-jet is based on the injection principle and an effective air-water mix is produced which results in optimum aeration and suspension of solids.
 

Surface Aerators:

Designed at various standard sizes, they provide required oxygen for specified application. Power range from 5.5 kW-75 kW. They are also available with floating system.

The surface aerators are mainly used at water purification plants for the biological treatment of the wastewater and at lagoons.

They can be both stationary and floating; the floating version consists of a floating system to which the aerator is fixed.
