Text version of the page

Applications The WS design is used for sludge dewatering in a wide range of industrial paint waste and surface treatment. Ideal for both small and medium-capacity installations WS decanter centrifuges are designed to be efficient, simple to install, easy to maintain and straightforward to operate. Installation, operating and service life costs are minimal. The WS range features • fully enclosed process sections • critical parts made of wear-resistant material • high performance combined with low energy consumption. Benefits • recycling of liquids • reduces sludge volume, which cuts down on transport and disposal costs • continuous operation • compact, modular design saves space • low installed power reduces electricity consumption. Working principle Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor (see drawing on page two). The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that stems from the rotation then causes sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl. The cake leaves the bowl through the solids discharge openings into the casing. Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.
