ECO-efficient management of WAter in the MAnufacturing industry
The effluents from the metal and plastic surface processing industry, particularly from galvanization, are rich in organic loading, salts, and heavy but valuable metals like nickel, copper and zinc. Led by the Fraunhofer IGB, the ECOWAMA project (“ECO-efficient management of WAter in the MAnufacturing industry”) seeks to develop an efficient and cost-effective method for electrochemical treatment of the effluents of the project partners from France, Spain, the Netherlands and Germany. The goal is to recover valuable materials and reuse them in the production process. In times of rising prices on the global market, metals are particularly valuable. At the same time the hydrogen arising from the electrolytic treatment of water is to be recovered as electrical energy to improve energy efficiency.
