In numerous production processes water is used as a solvent or means of conveyance, as cooling water or washing water. Increasing costs for the purification and disposal of wastewater, regional or seasonal shortage of water, and a growing awareness of environmental issues within companies have increased water recycling. Water is used several times and impurities have to be removed selectively.
The use of oxidative and electrolytic processes for water treatment is one of the main fields of research of Fraunhofer IGB. We work on the improvement of existing processes such as adsorption, filtration, flocculation/precipitation, electrodialysis, homogenization and disinfection as well as on new approaches in process and unit operations. Water treatment and the circulation of process water can thus be carried out economically and sustainably.
