Sewage & Water Treatment

Sewage and water treatment plants remove physical, chemical and
biological contaminants from wastewater. Due to the essential nature of
these facilities, reliable power is a critical component to maintain
24/7 operations. To support these installations, we offer diesel
generator sets covering the complete power range, and featuring
industry-leading reliability and availability. While mtu diesel systems
provide backup and standby power 24/7, our CHP modules provide one of the most economical ways for sewage plants to utilize waste energy.

Sewage gas, much like landfill gas, is freely available fuel onsite and
highly efficient. From about 6m³ of sewage, mtu systems generate an
average of 1 kWe of electric power and 1.2kWe of thermal energy. The
electric power generated by the system can be used to supply the sewage
plant itself or it can be fed into the electric grid. And the thermal heat generated inside the engine during the combustion process can be
utilized for heating up the sewage sludge in the digester or for heating
the whole facility. In large-scale plants, excessive high-temperature
heat may be available that can be used to pasteurize or dry the sewage
sludge.
