Abstract
Apparatus for extracting liquid from a suspension includes a horizontally mounted rotatable filter media covered concentrator drum with an inner drum rotatable about a horizontal axis within the concentrator drum and defining a suspension transition chamber therebetween. The drums are mounted in a common frame and are rotated in opposite directions with the suspension being introduced at one end of the transition chamber. Angularly disposed vanes on the outer surface of the inner drum convey the suspension through the transition chamber and turn and lift the suspension to a maximum elevation below the top of the transition chamber with the suspension falling back before reaching the top of the transition chamber. The filter media is cleaned as it moves at an elevation above the suspension.
