Step Screen

The STEP SCREEN is a great solution for medium depuration plants and it’s based too on the same constructive principles of the Multi Raked Bar Screen but with substantial differences. The machine has been created for a “in channel” installation with a 45° inclination until a 55° maximum and has a unique filtration system made by alternate fixed and mobile serrated lamellae. These lamellae perform the functions of screening and transport at the same time and when the waste water is filtered, the resulting effluents are blocked by the lamellae and transported to the discharge Thanks to the lamellae serration, the transport of the waste to the discharge works step by step with an eccentric movement of the mobile lamellae relative to fixed ones.
