The water treatment plant for the pre-treatment of well water

The company of the chemical and pharmaceutical industry operates a water treatment plant at its site in Germany for the pretreatment of well water for further use and treatment as process water (deionised water). The water treatment plant was built by Preussag Noell AG in 1989 and has been in operation since then.

The plant had to be modernised (retrofit) in order to guarantee economic and reliable operation in the long term, taking into account the current technical state of the art.
