Abstract: The invention provides a method and apparatus for removing suspended solids from liquids. In carrying out the method, a liquid containing suspended solids is delivered to a screen with a directional component across the screen surface and a directional component through the screen. The screen has openings that are large enough to pass a majority of the suspended solids, and the screen has the ability to hold a layer of the solids on the upstream side thereof. The flow of the liquid is controlled so that the coating is formed and maintained on the screen, and serves as a filtration medium. The invention also provides improved apparatus which comprises means defining a liquid filtration zone having a screen separating it into influent and effluent zones. The screen has openings large enough to pass the majority of suspended solids and has the ability to hold a layer of the solids on the upstream side. Means are provided for delivering liquids and suspended solids to the screen with a directional component parallel to the face of the screen and a directional component through the screen.
