WASTE WATER Solutions ROTAMAT® Storm Screen for stormwater discharges RoK 1 Automatically cleaned screen for solids retention in stormwater tanks and overows – Ecient solids separation – Continuous automatic screen cleaning – Dened solids removal – For discharges with limited upstream head possibilities – Sturdy, low-maintenance stainless steel design

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. Frequently, even the installation of scum boards is insufficient to prevent such pollution. The polluting items, such as sanitary products, toilet paper, faeces, plastic foils, etc. are not only unsightly but also responsible for considerable cleaning and/or disposal costs. On the basis of the DWA sheet A 128 (an instruction issued by an association dealing with wastewater treatment) efforts to fundamentally improve the protection...

On the left or right side of the weir overflow – standard inclination angles 0° and 60°. To allow far different structural conditions and local hydraulic conditions it is necessary that the screen can be flexibly installed into existing buildings. The full screen surface is available already at the beginning of a storm event so that the hydraulic resistance is minimized with the result of a very high solids retention. HUBER ROTAMAT® Screens RoK 1 can be used for a variety of applications in the combined sewage sector. To avoid another point of maintenance it is generally not intended to remove...
