An anaerobic stabilization pond is designed for a residentialarea have a population of 8000 (wastewater production is 225L/day-capita). Pond is designed as a facultative pond andmaturation pond in series. The BOD of raw sewage is 180 mg/L, theinfluent FC is 106 FC/100 mL and the operating temperature is 12°C.The effluent BOD concentration should be lower than 20 mg/L. Designcompletely both ponds using the relevant information andassumptions to provide an efficient design.
