www.waterinfocenter.com Aerobic digestion has been widely used in wastewater treatment plants (WWTP) for many years. The purpose of aerobic sludge digestion is to stabilize raw sludge and produce biosolids for further treatment and disposal. The detention time required to reduce volatile solids and achieve stabilization for a digestion mixture of waste activated sludge and raw primary sludge is 10–15 days at an operating temperature of 20° C (68° F). 2 Traditionally, digesters have been… CONTINUE READING
