AUTO DE‐SLUDGING CENTRIFUGES

What is an Auto De-Sludging Centrifuge

Auto De-Sludging Centrifuge, is a disc type centrifuge in which a carefully designed system opens ports in the bowl periphery at controlled intervals in order to remove the collected solids. The sludge is ejected out instantly due to the extremely hi g-force at the periphery of the rotating bowl. These Alfa Laval centrifuges are also known as Self-Cleaning centrifuges.

For what applications is an Self-Cleaning Centrifuge best suited?

Due to the intermittent nature of the sludge ejection cycle, these self-cleaning disc centrifuges are best for application where the %sludge (%sediment) is < 5% v/v. At higher solid load levels the sludge ejection frequency increases to a point where the centrifuge efficiency starts getting adversely affected. At higher (> 5% v/v) sludge loads a Alfa Laval decanter centrifuge is recommended to de-sludge the fluid prior to a self-cleaning centrifuge being used as a polishing stage.

In cases where there are no solids or the solids are negligible (< 0.05% v/v), a Alfa Laval Manual Cleaning Centrifuge maybe be used for separation of the 2-liquid phases. Any solids (down to 0.5µ) are separated as well and are accumulated in the bowl of the centrifuge for manual evacuation.
