Electrochemical WAter treatment system in the dairy industry with hydroGEN REcovery and electricity production
In the REWAGEN project (Electrochemical WAter treatment system in the dairy industry with hydroGEN REcovery and electricity production), a European project consortium consisting of partners from research and industry and led by the Fraunhofer IGB is developing a multistage process for the efficient electrochemical treatment of effluents from the dairy industry. The aim is to combine and integrate the individual process steps to form a closed system where each step delivers a stream of materials that can be further processed, recycled or reintroduced into the system. Thus the electrolytic treatment of water will yield hydrogen, which can be used to provide parts of the installation with electrical energy. The treated water can be reused directly as required. A modular construction allows the system to be adapted flexibly to the quantities of effluent at smaller dairies and milk-processing operations.
