Actual energy consumption of small-scale sewage treatment plants

Abstract

　There are few studies on the actual power consumption of small-scale sewage treatment plants, and the feasible energy-saving measures are not clear.

　Characteristics of electricity consumption intensity of small treatment plants were summarized using statistical data and estimates. Through hearing surveys at actual small-scale sewage treatment plants, the cause of high power consumption was estimated. Based on these survey results, we examined energy-saving measures.
