H2Office was asked to perform a detailled energy analysis, which would serve as basis for optimizing the energy consumption of the WWTP Bad Wörishofen (43.000 EP). The analysis was conducted on basis of the regulations of a funding program from the local authorities of Bavaria.
Another aim was to assess possibilities of improving the biogas production by introducing co-fermentation.
The energy analysis was conducted following the detailed regulations of the funding program in close collaboration with the operator. Missing data were collected during a defined measuring period.
Different aspects, which influence effluent concentrations as well as operation costs, have been evaluated in respect to energy consumption as well as process efficiency. Thereby a significant energy savings potential could be determined, without deteriorating the effluent quality.
Furthermore a cost-benefit analysis was carried out regarding the modernization of the CHP units including the possibility of providing surplus heat to a district heating system.
