摘要

Electric bills are a major operating expense for most water and wastewater facilities. Since motor systems, such as pumps, dominate consumption, they offer a major opportunity for energy savings without sacrificing facility performance Water and wastewater treatment facilities account for three percent of electricity use in the USA at a cost of some US$ 6.5 billion annually. Pumping accounts for over 95% of total electricity use in these facilities, with 85% consumed by distribution pumping. In wastewater facilities, blowers for aeration of activated sludge account for half the electricity, and pumping for 15%.
