Water Treatment

An important part of our vast product range is water treatment. With the acquisition of Vahldiek Prozess-Service (VPS) in 2009, CG Chemikalien has increased its know-how – with extensive experience in the area of industrial water treatment. Thanks to our versatile portfolio with roughly 2,500 basic and specialty chemicals we are able to offer all products for water treatment from a single source. The development and production of our own EVC® water treatment product line takes the special requirements of our customers and their water-bearing systems into consideration. Our consulting by experienced field service staff is supported by members of our application technology division and our in-house water lab.
