Storm Screen ROTAMAT® RoK1 for stormwater discharges
Manufacturer: Huber Technologies
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 storm water. 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 storm water 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. Alternatively, the screenings are removed from the plant with a pump for further disposal. During storm conditions the screen is automatically started and then works fully automatically.
Optimal solids retention by means of two-dimensional screening (perforated plate)
Low hydraulic resistance due to installation behind the overflow at weir height
The perfect solution for discharges with limited upstream head possibilities
Defined screenings discharge
Problem-free retrofitting into existing structures
Possibility of completely submerging the screen
