Apparatus for the separation of material suspended in a liquid, comprising a vessel 2 into which the suspension to be treated is fed and a rotary filter drum partially immersed in the suspension, wherein this filter drum together with another drum form a pair of cooperating, counter- rotating drums 1 of which at least one is a filter drum rotatably mounted on two end carrier means, a stationary shield arrangement 7 being mounted on the carrier means within the drum and dividing the interior of the drum into sections, at least one of these sections C-F being connectable to a vacuum source for reducing the air pressure in that section. The filler is cleaned by a high pressure blast applied through section I and the sludge removed by a scraper 15. <IMAGE> |
