Jet type Aerator is a submersible pump combined with a ventri and jet based diffuser. The primarry purpose is to transfer oxygen to the liquid or sludge. 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 simultanously agitating and aerating the ponded water. The mixed air water is ejected powerfully in one direction which effectively agitates the water across a wide area.
