Drinking water is normally sterilised by chemical means or at the least with the help of chemicals, e.g. chlorine. An innovative chemical-free process is used for this application. The plant developer/ constructor was awarded the Innovation Prize from the Bundesministerium für Wirtschaft und Arbeit[Federal Ministry for Economics and Labour] for this device in 2004. The further advantages of this treatment option are that the entire treatment system is compact and easy to transport. Moreover, commissioning is as easy as pie because the water treatment is absolutely fully automatic.
