Higher the ABS production higher the wastewater generation. The ABS wastewater contains high strength of organic carbon and organic nitrogen. The large quantity of waste sludge, produced from the high nitrogenous wastewater treatment process, contains significantly complex and difficult-biodegraded organics. Thus, this sludge needs to be managed before its ultimate disposal. Anaerobic digestion is often used in the treatment and disposal of waste sludge. This process not only treats the waste sludge but also regards it as resource recovery. It is one of the best methods to reduce the cost of operation.
