RSS Series of Externally-fed Rotary Screens have slotted wedgewire, cylindrical drums that rotate on two pillow block bearings. The screen slot openings range from 0.100 to 0.010 inches. The rotary drum is driven by a TEFC motor fitted to a shaft-mounted gearbox The self-cleaning action of the water falling through these screens, is ideally suited for flows that have high oil or grease loadings.

Method of Operation
Raw influent enters a headbox which distributes the flow evenly across the full length of the rear, upper external surface of the rotating drum. As water passes through the screen, solids are retained on the outside of the screen drum and are carried by rotation around to the front of the screen, where they are removed by a fixed doctor blade. The screened water cascades down inside the drum and falls through the bottom, creating a vigorous backwash action. This action, together with the use of internal water sprays, self-cleans the drum on every revolution.
