Combined Heat and Power Systems for Wastewater Treatment Plants

Our WWTP cogenerations operate depending on the amount of digester gas emitted; the gas engines will run as long as there is sufficient sewage gas available. The digester in a wastewater treatment plant requires lots of heat, so there‘s almost never excess heat generated. The power produced can either be used to operate wastewater pumps, the aeration system and other electric consumers of the plant or it can be fed into the public grid or other supply channels.

The engines used in f.u.n.k.e. SENERGIE WWTP cogenerations operate in a lean burn mode. This leads to significantly reduced emissions. Exhaust gases emitted generally require no further treatment.

Sewage gas may contain substances like H2S or siloxanes that can damage the system’s engine. In those cases, the substances must be removed first. f.u.n.k.e. SENERGIE also knows a perfect solution for this potential problem – ask us about it.

The f.u.n.k.e. SENERGIE combined heat and power systems are equipped with a control system. It also communicates via potential-free contacts and/or data bus with the WWTP’s process control system. Of course, remote acces via Internet is also possible.
