Efficiency Analysis of Aerobic and Anaerobic Digestion System in Controlling COD during the Reclamation of Domestic Sewage Water

This work is a comparative study of aerobic and anaerobic digestion of wastewater for minimizing the Chemical Oxygen Demand to improve the efficiency of wastewater management and reclamation. Aerobic and anaerobic treatment methods are simulated by varying the reactor tank depth to reduce Chemical Oxygen Demand. In the first set of aerobic treatment, the tank depth is 3 (m2) and the Chemical Oxygen Demand in the effluent is 51.57 (mg/l), In the first set of anaerobic treatment, the tank depth is 3 (m2) and the Chemical Oxygen Demand in the effluent is 197.6 (mg/l). From the obtained results, aerobic treatment reduces COD with better efficiency than anaerobic treatment.
