In the first step of the project funded by the German Federal Ministry for Education and Research (BMBF) three UF pilot systems (about 10 m3/h) were evaluated for drinking water treatment of reservoir water. In the second step a 150 m3/h pilot plant with 12 6 m long pressure vessels was installed in the waterworks of Roetgen. One of the unique features of the pilot is, that the inlet and outlet flows of every pressure vessel are monitored. Further on a particle counter is installed. With this particle counter the filtrate of every pressure vessel can be monitored automatically by switching magnetic valves.
