Degradation of ammonia in an integrated anoxic-aerobic clarifier system

Wastewater effluent discharge in a large concentration of ammonia, nitrate and phosphorus lead to eutrophication the river. Eutrophication is a serious environmental issue that threatens the fishes and aquatic plants. To prevent this from happening, ammonia produced in sewage treatment plant (STP) a...
