TOTAL ENERGY CONSUMPTION FOR MUNICIPAL WASTEWATER TREATMENT

Smith, R. TOTAL ENERGY CONSUMPTION FOR MUNICIPAL WASTEWATER TREATMENT. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-78/149 (NTIS PB286688), 1978.
Description:
Quantities of all forms of energy consumed for collection and treatment of municipal wastewater are estimated. Heat energy is equated to electrical energy by a conversion factor of 10,500 Btu/kwh. Total energy consumption, expressed as kwh/mg of wastewater treated, ranges from 2300-3700 kwh/mg. Energy used for construction of the treatment plant and the seweage system represents 35-55% of the total energy consumed. The remainder used for plant operation is predominately (65-75%) electrical energy. The use of high efficiency aeration devices combined with good maintenance practices appears to offer the best opportunity for conservation of energy within the plant.
