NEW! Skid-mounted decanter centrifuge system

Jan 29 2010

Alfa Laval’s (USA) new Decanter Centrifuge System is a mobile solution for reducing sludge volumes at municipal, industrial and potable water treatment plants. Its plug-and-play design allows for rapid and easy installation on-site.

This self-contained system includes all the key components required for dewatering and thickening waste sludge on-site. It is a versatile solution designed for use in dewatering many of the sludge types commonly encountered in conjunction with industrial applications and municipal wastewater treatment plants.

Based upon Alfa Laval’s proven technology, the ALDEC decanter centrifuge, this system can be customized to fit specific requirements – offering increased flexibility. The system features ALDEC and G2 decanter centrifuges, including ALDEC-30, G2-45, G2-60 and G2-90.

The progressing cavity feed pump feeds the sludge by an electromagnetic flow meter into the ALDEC decanter centrifuge. The pump is driven by a variable frequency drive to permit adjustment of dewatering capacity. The polymer feed system introduces the polymer simultaneously into the decanter bowl to aid flocculation of the sludge. Instantaneous sludge sedimentation takes place in the decanter centrifuge due to the effects of high centrifugal force.

An external screw conveyor then transfers the sludge cake to the cake collection point, and the clarified liquid is discharged by a pipe at the bottom of the module. A combined control/starter panel is used to start/stop all the equipment in the complete module to control them while in operation.
