The waste water flows through a grid rack of steel or stainless steel which retains contamination products. The cleaning carriage is moved by a trunnion rack and pinion drive system. The path and angle of the cleaning rake are controlled by side rollers running in a guide track. At the lower turning point, the rake protrudes through the grid, so that screenings cannot get stuck. Solid matter is directly picked up by a special cleaning rake at the channel bottom; there is no need for a discontinuity in the channel bottom. Screenings are pushed into a container, screenings press, screw container, belt conveyor etc. via a pivoting stripper. The screen can be mounted vertically in flumes and can be arranged as a forward flow or reverse flow unit.
