Short description

Municipal wastewater treatment in Europe requires a significant amount of energy to eliminate organic matter and nutrients (i.e. nitrogen and phosphorus) from the sewage prior to its discharge. The Horizon 2020 EU-Projekt POWERSTEP aims at demonstrating that through novel treatment concepts and the optimized integration of existing technologies wastewater treatment plants (WWTP) can improve their energy balance and even become net energy producers. POWERSTEP brings together expertise and resources from both the public and private sector, as well as from universities and research institutions from 7 different European countries. The project with a budget of 5.2 million euro is coordinated by Kompetenzzentrum Wasser Berlin.

The IWR-Institute plays a central role in the project and will implement at the Austrian WWTP Kirchbichl an innovative concept to treat sludge dewatering effluent that can significantly improve the energy balance of the plant. Emphasis will be placed on the integration of the side stream treatment in the whole wastewater treatment concept.
