The waste water treatment plant in Stuttgart-Muhlhausen is setting up a second channel for disposing of the sewage sludge in addition to spreading it on farm land: it is to use sludge dewatering.

The waste water treatment plant Stuttgart-Muhlhausen, which is responsible for treating the waste water of the city of Stuttgart, is currently pursuing the strategy which has been adopted by all major waste water treatment plants in Germany for political reasons: it is setting up a second channel for disposing of the sewage sludge in addition to spreading it on farm land. This practice will be extended up to the beginning of 2007 to include a dewatering and drying facility before being conveyed to the block heating station Muhlhausen. After the planning order was placed, Westfalia Separator Umwelttechnik, Oelde/Sangerhausen, received an order for two decanters type UCD 755 for dewatering the sewage sludge and connecting the dryers via a sludge discharge scroll.

The new UCD 755 series is being installed for the first time in a municipal waste water treatment plant.

The decanters with an inside bowl diameter of 750 mm achieve a maximum hydraulic capacity of 140 m3/h.
