Activated sludge process wastewater treatment methods

The activated sludge process is a type of wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. The general arrangement of an activated sludge process for removing carbonaceous pollution includes the following items: An aeration tank where air is injected in the mixed liquor. This is followed by a settling tank to allow the biological flocs to settle, thus separating the biological sludge from the clear treated water.- wikipedia[]
