The basis for a successful market entry in Europe is the CE marking of your product. For this purpose, the series of standards – EN 12566 – is used. Five of the seven standards have been harmonised and, with our support, you can receive a declaration of performance according to one of these standards and place it on your product. With it, small wastewater treatment plants can be traded legally throughout Europe.
