The ALDEC range of decanter centrifuges was developed with
a focus on cost-efficiency, reliability and easy operation. The
ALDEC design is used for sludge dewatering in a wide range
of industrial wastewater treatment applications, as well as
municipal wastewater treatment plants.
Ideal for both small and medium-capacity installations
ALDEC 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 ALDEC range features
• fully enclosed process sections
• critical parts made of wear-resistant material
• high performance combined with low energy consumption.
The ALDEC decanter centrifuge design provides a series of
• reduces sludge volume, which cuts down on transport and
• continuous operation
• compact, modular design saves space
• low installed power reduces electricity consumption.
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 results 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
slightly slower, 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.
