Applications
The WS design is used for sludge dewatering in a wide
range of industrial paint waste, surface treatment and
waste oil applications.
Ideal for 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.
