An Integrated Approach to the Biological Reactor–Sedimentation Tank System

An Integrated Approach to the Biological Reactor–Sedimentation Tank System

Secondary clarifiers are demanded to separate solids created in activated sludge biological processes to achieve both a clarified effluent and to manage the biological processes itself. Indeed, the biological process may influence the sludge characteristics, and conversely, the settling efficiency o...
