Disclosed are barrier coatings for fused silica components used in semiconductor processing. In particular, the present disclosure concerns protective substrate-barrier coatings composed of corrosion-resilient metal compounds which provide superior resistance to erosion/corrosion when a coated substrate is subjected to the acidic environments at elevated temperatures typical for semiconductor processing.

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.
