Sludge decanter centrifuge design provides a series of concrete benefits

  • Reduces sludge volume during the sludge thickening and dewatering process, which cuts down on transport and disposal costs
  • High capacity at small footprint: Compact, modular design saves space
  • High performance combined with low energy consumption
  • Wear-resistant design with anti-blocking feature.
  • Complete, fully enclosed cleaning-in-place (CIP)

The extensive range of ALDEC centrifuges for sludge thickening and dewatering are capable of handling a wide range of flow rates. They are designed to be efficient, simple to install, easy to maintain and straightforward to operate. Installation, operating and service life costs are minimal.

Sludge thickening and dewatering - Less water, lower cost

Cost-effective sludge decanter centrifuges are crucial for removing the water content from sludge from wastewater plants, as well as from industrial waste streams. The drier the sludge, the less space it takes up and the less it weighs – both resulting in big savings on transport and disposal costs, whilst helping to meet sustainability requirements.  

Low energy consumption and labour costs

When using the ALDEC decanter centrifuges in your sludge thickening and dewatering process, you benefit from low energy consumption as well as a minimum of maintenance costs, keeping dewatering costs to a minimum. They are also fully automatic, so you can keep labour costs down.

How does sludge thickening and dewatering work?

In the sludge thickening and dewatering process, separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. 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.
