Rotary drum vacuum filters consist of a rotating drum lined with filter medium that has approximately one third of its outer wall submersed in the slurry. The filtrate is pulled through the wall of the drum by a vacuum, towards the center of the drum. The drum rotates such that the cake is dumped to the discharge outlet.
