Description

GVS Sub-vertical Mechanical Screens consist of a robust steel frame and a perforated plate filter varying according to the screening efficiency required.
GVS screens, which are equipped with brushes and wiper blades, are suitable for fine screening of sewage in both municipal and industrial plants, as well as, in particular, for process water of industrial processing plants.

Function

Waste water flows into the upstream end of the unit where screenings are captured on a perforated plate filter.
Chain-driven brushes and wiper blades clean the perforated plate filter conveying at the same time solids to the discharge point.
Material is removed from the rakes by a wiper and discharged into a dumpster, conveyor or compactor.
