A Jet Aerator is a high-efficiency aeration device that combines a submersible pump with a venturi injector and a jet-type diffuser to achieve simultaneous aeration of wastewater or sludge. Its primary function is to transfer oxygen into the liquid medium, promoting aerobic biological treatment and maintaining homogeneous mixing within the treatment basin.

Jet aerators are easily configured into any basin geometry including circular, rectangular, looped reactors and sloped wall basins. In this aerator the aspirated air mixes with water and is ejected through the diffuser simultaneously agitating and aerating the ponded water.
