The treatment of wastewater by suspended growth biological treatment is known as the activated sludge process. In activated sludge process wastewater containing organic matter is aerated in an aeration basin in which micro-organisms metabolize the suspended and soluble organic matter. Part of organic matter is synthesized into new cells and part is oxidized to CO2 and water to derive energy. In activated sludge systems the new cells formed in the reaction are removed from the liquid stream in the form of a flocculent sludge in settling tanks. A part of this settled biomass, described as activated sludge is returned to the aeration tank and the remaining forms waste or excess sludge with sewage sent to clarifier for sludge settling and clear water sent to clarified water tank for disinfect and make it free of disease-causing organisms. At the end of the process the effluent water is treated to disinfect it and make it free of disease-causing organisms.
