Description
CATEGORY SEWAGE
TYPOLOGY SCREENS
WHEN TO USE IT
The GCM curved screen with mechanical cleaning is intended for installation in small and medium sewage treatment plants where channels are shallow. It addresses common screening requirements for such sites, providing reliable separation of coarse solids.
HOW IT IS MADE
The unit consists of a curved bar filtering screen matched to a pair of cleaning combs fixed to the ends of a rotating arm. The drive is provided by a gearmotor mounted directly on the rotating arm. Comb cleaning is actuated by a double-cam operated cleaner designed to ensure effective cleaning and long service life. Screened material is either collected in a fixed container placed immediately downstream of the screen or discharged via a conveyor belt.
HOW IT WORKS
In the standard configuration the GCM screen is installed in a concrete channel through which the water flows. Solids with a diameter equal to or greater than the screen opening (determined by bar spacing) are retained on the curved screen. When buildup causes a headloss between upstream and downstream, a differential level sensor commands rotation of the arm: the two combs clean the screen as the arm moves. When the arm reaches horizontal, the comb that has just cleaned the filtering surface is itself cleaned by the cleaner and the removed material is dumped into the downstream container.
