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, MTU Onsite Energy offers diesel generator sets covering the complete power range, and featuring industry-leading reliability and availability.

While MTU Onsite Energy 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 Onsite Energy 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.
