Abstract
A screening device for separating out and removing contaminants from wastewater includes two continuous conveyors, which are mounted with clearance from each other. Each has a drive wheel that is guided on a circular path and includes a fixedly situated bar screen, which includes multiple mutually spaced grating bars for removing contaminants from the wastewater. Each bar screen includes multiple clearing elements, which are connected to the conveyor for removing from the bar screen the contaminants that have been separated out by the bar screen. The bar screen forms a fixed screen surface that extends, in the intended installation position of the screening device, essentially in the flow direction of the wastewater reaching the screening device.
