GEMÜ butterfl y valves at the Trollmühle Waterworks - Uranium removal and partial deionization using Uranex® and Carix® procedures

Currently, the waterworks at the Trollmühle water supply authority in Windesheim near Bingen am Rhein supply approximately 43,000 people in 14,000 households with 2.2 million m³ drinking water per year. At peak times, this means a daily dispensing volume of up to 8500 m³. On the one hand, Krüger WABAG / VWS Deutschland GmbH implemented the URANEX® system, which is used to minimise the water‘s geologically caused uranium content by means of ion exchange. On the other hand, partial deionization by ion exchange is achieved using the CARIX® procedure.
