Submersible Aerator, For Pond Aeration, Sewage Treatment

Sewage sludge is highly reactive. Long-term storage may lead to septic conditions resulting in bad odors which bother not only residents. The aeration of sludge limits the formation of odors caused by anaerobic bacteria. The sludge is kept fresh. Additional treatment of the off-gas is not required. The aerator provides for effective aeration and thorough mixing of the sludge and simultaneously controls the foam layer. 

Thus capital costs are reduced. In case redundancy is needed several smaller units can be used. Basically the aerator consists of drive, foam cone and impeller. The rotating impeller sucks sludge from below and air or foam from above through the foam cone and swirls the mixture of both radially to the sides.

The unique design of the Aerator makes it very sturdy and low-maintenance. There are no bearings or seals in the immerged part and all submerged parts are made of stainless steel or plastics. Aerator with Foam Control can either be mounted with a mounting bracket or on float assemblies.
