Used Centrifuge Decanter Working principle
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 rotor. Centrifugal forces cause 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 Used Decanter Centrifuge design enables the hydraulic pressure inside the bowl to enhance scrolling through a narrow opening. This means that only the very driest fraction of the sludge cake leaves the bowl through the solids discharge openings into the casing. Separation takes place along the total length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.
Benefits of Used Decanter Centrifuge ALDEC 508
• reduces sludge volume, which cuts down on transport and disposal costs
• continuous operation
• compact, modular design saves space
• low installed power reduces electricity consumption
