These tanks, also known as Main clarifiers, present about two several hours of detention time for gravity settling to happen. Given that the sewage flows via them slowly and gradually, the solids step by step sink to The underside.
A substitute for the activated sludge procedure could be the trickling filter method. In this process, wastewater is sprayed around a mattress of Wastewater Treatment media, including rocks or plastic, forming a biofilm wherever microorganisms reside.
