Vodatech - Rotary Screens - Brochure

Rotary screen RS is used for continuous separation of solid pollution in waste water. The main operational part of rotary screen is a slot tube which is a welded structure with support profiles which are rods in the axial direction of the tube and surface profiles spirally wound around the support profiles. Water is conveyed by a pump or flows with gravity on the slot tube and passes through slots. The solid pollution that exceeds the dimension of the slot, remains on the exterior of the rotating slot tube and it is scrapped and falls down in a container. Treated water, free of solid pollution, flows out from the lower part of the rotary screen.
