OHIO WWTP SEEKS $$ FROM THEIR FLARED DIGESTER GAS
City of Newark Ohio’s Division of Water and WastewaterNewark, Ohio
The City of Newark Ohio’s Division of Water and Wastewater tried something new to recover
the energy and generate revenue from biogas produced by their anaerobic digesters. The City’s 8
mgd WWTP is equipped with three anaerobic digesters, which collectively produce an average
of 100 mcfd of biogas. This gas is used for facility heat and process heat, with the balance of
approximately 50%, flared. This waste of energy and the environmental consequences of
burning fossil fuels has long been an issue with the Division, so they began exploring
alternatives to flaring. Generating electricity with the gas was investigated, but the high capital
and maintenance costs for the generation equipment and the gas cleanup costs made it financially
unattractive. They were looking for an economically viable alternative.
