Chemineer agitators are playing a key role in six newly-upgraded activated sludge process lanes at Severn Trent Water's WWTW in Birmingham, Ala. Installed in six phases with no disruption to operations, the 24 Chemineer Model 20 GT agitators are successfully homogenizing fluid streams prior to aeration, as well as ensuring there is no return flow from the aeration lanes back into the anoxic zones. Operating 24/7, each agitator utilizes a high-efficiency HE-3 impeller, rotating at a low rpm.
