Monitoring Integrated Energy Systems at a Wastewater Treatment Plant in Maine

摘要

A project was undertaken to monitor the performance of an integrated energy system at the Wilton, Maine, wastewater treatment plant. These systems included active and passive solar heating, effluent heat recovery, digester gas generation, air-to-air heat recovery, and electricity generation using digester gas. To accomplish the monitoring, an instrumentation system was installed and data were collected over the period from May 1979 to March 1981. This instrumentation system includes solar pyranometers, hydronic BTU computers, electrical and gas meters, a weather station, and numerous temperature transmitters. Data for the solar and digester systems are available in both digital and analog forms.
