摘要

In the fall of 1983, the city of Bingen was selected as a target community for the Local Government Technical Assistance (LGTA) Program. They requested the LGTA team to assist them in identifying cost-effective energy conservation opportunities at their wastewater treatment facility. A description of the wastewater treatment process, monthly energy cost and consumption data, and process in-flow data were collected and analyzed by the LGTA team. An onsite treatment facility evaluation was performed in March of 1984. The purpose of this report is to present the results of the LGTA energy inventory and to recommend directions for further study. The city of Bingen operates a small treatment plant which averages 9.6 million gallons per month (an average of 0.31 million gallons per day). The treatment process consists of passing wastewater through a comminutor, grit chamber, aeration basin, clarifier, and a chlorination contact chamber prior to releasing the treated water into the Columbia River. The solids portion of the waste stream is biologically treated by aerobic digesters before the sludge is trucked to a land disposal site. Annual electrical consumption at the facility averages about 80,000 kWh. As estimated by the LGTA equipment inventory, the largest electrical consuming process component is the operation of the brush aerators (approx.65% of the total process electrical consumption). An Energy Utilization Index (EUI) was determined on a bimonthly basis. Over the last 18 months, the EUI has averaged a very respectable 2.67 million Btus per million gallons of processed wastewater.
