Decanter Centrifuge ALDEC506 Applications
The decanter centrifuge ALDEC506 was developed with a focus on cost-efficiency, reliability and easy operation. The ALDEC506 is used for sludge dewatering in a wide range of industrial wastewater treatment applications, as well as municipal wastewater treatment plants.
Technical parameters:
Bowl ID: 450 mm
L/D: 4.2
Bowl speed: 3250 rpm
Motor: 37 Kw
Capacity: 20 m3/h
Manufacturing year: 2002
Materials
The bowl, conveyor, inlet tube, outlets, cover and other parts in direct contact with the process media are all made of stainless steel. The discharge ports, conveyor flights and feed zone are protected with materials that are highly resistant to erosion. The frame is made of mild steel with an epoxy enamel finish.
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 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.
