Wastewater treatment at biogas plants
In terms of environmental and water protection, the operation of biogas power plants is more and more being subject to the attention of governmental authorities and other responsible institutions. In Germany for example, it is not allowed to drain away run-off rainwater from traffic areas of biogas plants without prior wastewater treatment. Also, there may be a need for action in case of the possible contamination of subterranean water by means of silage-leachate.
Wastewater treatment systems with fixed-beds for the growth of micro-organisms, like our DELPHIN® treatment plants, provide huge advantages for the scenarios mentioned above and are successful clarifying run-off rainwater or contaminated subterranean water already.
For background Information about the operation of a DELPHIN® compact wastewater treatment plant in order to clarify subterranean water, which was contaminated by silage-leachate, see report of NR-Kurier (Neuwied-Rhein Kurier) from 12.12.2012 (German language):
