Application
The raw water is pumped from the lake into a tank. It is then filtered via a drum filter. In this process the water is separated and purified from any suspended matter and coarse impurities. An electronic differential pressure measuring instrument monitors the level of contamination of the filter. Cleaning of the filter is automatically triggered as soon as the threshold contamination is exceeded.
