RFP-1625-06-SDH - Persigo Wastewater Treatment Plant Energy Conservation Study

Summary of Specifications:
The purpose of this RFP is to obtain competitive proposals from qualified individuals or firms, interested in providing professional services to perform an Energy Conservation study at the Persigo Wastewater Treatment Facility. The study should focus on the beneficial use of methane gas being produced in the anaerobic digester process. Persigo is using a portion of this gas to provide heat for the anaerobic digestion process, as well as to heat several buildings at the treatment plant. The anaerobic digestion process is producing approximately 24 million cubic feet/year over current usage. This wasted gas is being sent to a waste gas burner. Wastewater treatment plants are heavy users of energy, and the use of methane recovery within anaerobic digesters can offset the current usage.
