ABSTRACT:
An apparatus is described which separates small solids from process waste water. A continuously rotating elongated drum screen in a three foot diameter flow channel removes the solids. The solids are deposited by spray wash into a dewatering chamber. The screen components include row of closely spaced links and pivot members connected end-to-end to form a continuous loop mounted within a frame driven by a variable speed motor.
