STEP SCREENS

GENERAL DESCRIPTION AND INTENDED USE

It is the pre-treatment equipment preferred as a fine screen in order to remove the solid materials coming to the wastewater treatment plant from the wastewater. They are mounted at an angle of 50°-70° on the horizontal axis and are generally manufactured with a screening range of 3-6 mm. They are preferred in cases where the channel height is low due to the low angle of the horizontal axis. They are equipment with optimum cost and high operating efficiency and they generally found at the entry of the facility. The wastes held by means of the movable and fixed metal sheets are gradually carried up the channel. Since it gradually carry the wastes up, the surface area to be screened is more than other screening methods. Thanks to the high removal efficiency, situations such as blockage and deterioration that may occur in the pumps, valves and the pipes are minimized, removal of the suspended solids is provided and treatment process is performed at a lower cost.
