A separator includes a continuous inclined screening belt that passes over an upper roller and a lower roller to screen debris from municipal wastewater. The debris is then conveyed to a debris discharge outlet. A puddle of debris-laden wastewater forms a hydrostatic pressure head on the upper surface of the screening belt to assist in forcing the wastewater through the screening belt. Wastewater that passes through apertures in the screening belt is deflected by a deflector plate that shields the return path of the screening belt. The screened wastewater is then directed to the wastewater outlet. In a preferred embodiment, a belt-cleaning brush is disposed along the return path and brushes clinging debris from the screening belt toward the debris discharge outlet. Additionally, the screening belt rides on and is supported by a perforated backing plate as it travels from the lower roller to the upper roller. Overflow ports are provided to allow wastewater from the puddle to bypass the screening belt if the screening belt becomes blinded. This prevents the wastewater from exiting the separator via the debris discharge port.

[ We claim:] [1.]1. A municipal waste separator comprising:an inlet configured to receive debris-laden wastewater;an inclined screening belt which passes over an upper roller and a lower roller, wherein said screening belt has a plurality of apertures through which a substantial portion of the wastewater passes, and wherein said screening belt conveys debris which does not pass through the apertures over the upper roller; anda puddle will configured to retain a puddle of debris-laden wastewater on an upper surface of the inclined screening belt near the lower roller, wherein said puddle creates a head of fluid sufficient to assist in forcing wastewater through the screening belt.
