Automatically cleaned screen for solids retention in stormwater tanks and overflows Efficient solids separation Continuous automatic screen cleaning Defined solids removal For discharges with limited upstream head possibilities Sturdy, low-maintenance stainless steel design The HUBER ROTAMAT® RoK1 storm screen belongs to a group of fine screens designed for high flow rates at an extremely low hydraulic resistance. Two-dimensional screening guarantees a very high solids retention combined with automatic, gentle cleaning of the perforated plate. During and after storm events large amounts of debris are discharged to streams, rivers and lakes through storm water overflows of combined and sanitary sewer systems. Particularly endangered receiving water courses and nature preservation areas require more extensive measures concerning the treatment of stormwater. The ROTAMAT® RoK 1 screen is the ideal solution for this task, whether for new structures or refurbishment. RoK 1 screens are horizontally installed directly behind the downstream side of overflow weirs. A screw flight is mounted on a half cylinder of perforated plate. As the stormwater flows through the horizontal perforated half-pipe of the screen trough the solids are retained. A screw, with a brush attached on ist flights, rotates within the semi-circular screen trough. It cleans the screen and pushes the screenings gently towards the end of the trough. At the end of the trough, the screenings are returned into the sewer and carried to the wastewater treatment plant.
