Step Fine Screens
From Wastewater Treatment Plant Drives and Equipment
The fine screens type Step Screen with width of slots 1.3 or 6 mm are designated for separation of floating mechanical impurities (screenings) from communal and industrial waste water. A filtration surface of screenings consists of fixed and mobile lamellae with a step-form. Coming screenings are collected on the steps and create a „screenings carpet“, which increase filtration effect of screens. The mobile lamellae driven by screens drive lift captured screenings up to the weir plate from where they fall down into the conveyor, water channel, screening press or directly into the container. The fine screens with mechanical cleaning Step Screen are completely made from a quality stainless steel.
