Rake screens can operate both in manual and automatic mode (mechanized screens) without the participation of maintenance personnel and are fully integrated with the automated control system of any complexity. Waste contained in sewage is retained with a filter cloth that is cleaned automatically or manually by the rakes. The retained waste is removed to the container or to the screw/belt conveyor and then, for further processing (washing and pressing), onto the screw press.
