Abstract

This fact sheet identifies the energy savings realized at a wastewater treatment plant (WWTP) in Pana, Illinois. The Pana WWTP went on line in 1986 to process sanitary wastewater from its 5,500 residents. Its design capacity is 3.3 million gallons per day (MGD) with a daily operating load of 1.7 MGD. Wanting to cut operating costs, the plant supervisor requested ISTC's assistance in identifying energy efficiency opportunities that would not interfere with the waste treatment process. Significant energy savings were identified by the installation of variable frequency drives (VFDs) on three 75 horsepower Hoffmann Blowers.
