Power Generation From Wastewater

Renewable Energy from Municipal & Industrial Waste with Cogeneration Systems

As towns, cities, and counties across the U.S. search for renewable energy sources, they are increasingly turning to their steady stream of municipal waste as a reliable source of fuel. Municipal wastewater treatment plants employing anaerobic digestion technology can turn wastewater into methane-rich biogas. And new small-scale wastewater treatment systems enable industrial facilities such as breweries and other food and beverage operations to treat their wastewater onsite, simultaneously reducing their wastewater disposal fees and generating their own renewable energy.

The Role of Cogeneration Systems

Reciprocating engine cogeneration (CHP) systems have a long track record of successful operation on biogas generated by anaerobic digestion-based wastewater treatment. The hot water produced by CHP systems can be used within the anaerobic digesters themselves, where it is essential to maintain an operating temperature of about 100F for the bacteria that act as the biological engine of the wastewater treatment.

Projects

WWTP Morag, Poland

TEDOM Poland commissioned a Cento T100 containerized CHP system at the wastewater treatment plant in Morag, Poland, in June 2015. The CHP system supplies the energy needs of the WWTP. In the event of a utility failure, it can also serve as an emergency source of electricity and heat to maintain the operability of the wastewater treatment plant technology.
