PERFORATED TYPE SCREENS

GENERAL DESCRIPTION AND INTENDED USE

Perforated type screens are mechanical equipment designed to remove undesired solids from the water received with wastewater from the free flowing channels. Thus, the cases such as blockage and malfunction in the pumps, valves and pipes are minimized and the pollution load of the wastewater is reduced and the treatment is performed with lower costs.

It removes the solid materials of which particle sizes are larger than grab screen gap (Ø3 + Ø10 cm in general). Generally, it is mounted in the screen channel with an inclination of 45°–75°.

It is generally used as thin screen in wastewater treatment facilities. Perforated type screens operate with thinner screen gaps compared to other screens.
