Activated sludge clarifier is a kind of aerobic biological treatment of sewage, which is the most common used method for treating urban sewage. Activated sludge clarifier removes soluble and colloidal biodegradable organics from sewage and suspended solids that can be adsorbed by activated sludge. Activated sludge clarifier also removes some of the P and N.
How it works?
The wastewater after the primary clarifiers is mixed with the activated sludge returned from the secondary clarifiers and then enters the aeration basin. After about 6 hours of aeration, the incoming water and return sludge are mixed by submersible aerator. During the flow, organic matter is removed by adsorption, flocculation and oxidation.Secondary Treatment design
