AR-HES-B – Energy storage, production and recovery of valuable substances in waste water treatment plants

The overall project goal of the AR-HES-B project is the technology rearrangement of the municipal wastewater treatment plant in order to transform the municipal wastewater treatment plant from a high energy consumer towards an optimal integrated hybrid energy provider, energy storage and resource provider in the urban environment. Via the AR-HES-B concepts the municipal sewage treatment turns into an important platform in the supraregional energy- and mass transfer. The wastewater treatment plant as a hybrid energy provider, energy storage and resource provider will be the intelligent alliance of wastewater-, electricity-, gas- and district heating grids right at the interface WWTP. Thereby storage peak loads can buffered by integrated sustainable solutions for in the district heating- and electricity grids.

The aim of the wastewater treatment in future is not only in utilization of the bound energy, but the utilization of all the valuable substances contained in the wastewater up to the usage of the cleaned water itself.

Beyond that, the required organisational framework conditions and the acceptance of the involved key players are clarified. The outcome of the project is going to be a detailed guideline “Future Wastewater Treatment Plant”, which contains all the summarised topics discussed in this project.
