12 SKE Spiraline Compact Treatment Plant CPS 1. The incoming effluent is pumped or flows to the STU/C, depending on the location. 2. Effluent flows through the screen. Solids are captured on the screening basket and as the screen blinds, the upstream level rises to a pre-determined level at which the screw operates and clears the screening basket. 3. While screenings are conveyed away from the screen surface to the discharge point, washing occurs in the conveying section of the conveyor. The spiral runs on heavy duty longitudinal wear bars which enable the screenings to de-water during elevation. Before screenings are discharged they are compacted in the compaction zone of the screen press. 4.
