Water production and treatment

Water is vital for humans and their environment. This being so, it is especially worthy of protection. For this reason, drinking water – procured from groundwater, bank filtrates, bodies of water or springs close to the Earth’s surface – must be free from harmful contamination after treatment. Hence, the aim of our engineers in research projects is to further improve the processes in drinking-water treatment and sustainable resource protection. So RWE intends to go on helping secure the high quality standards of the German water sector.   

Recognized worldwide 

One of the research successes is the development and use of the so-called "Mülheim process". Here, activated carbon, ozone and UV light are used to treat and disinfect raw water. The process lowers the cost of treating water. The method, which is recognized around the world, was developed by RWE's subsidiary Rheinisch Westfälische Wasserwerksgesellschaft mbH (RWW) with registered office in Mülheim. Other ongoing projects of RWE concern the modelling of material flows in the soil, the use of artificial neural networks in waterworks, the optimization of waterworks filters and the use of ozone in water treatment.
