Special filter system made of plastic for installation directly in a standard concrete manhole.
The ready-assembled rainwater treatment system can be quickly and reliably installed on site, as it is completely factory-installed in sufficiently dimensioned manhole structures.
The quality of the water treated by the modular rainwater treatment plant is so high that it can be discharged directly into infiltration, surface waters and biotopes. In the filter shaft, the rainwater is purified by the following procedural steps: sedimentation, adsorption, filtration and chemical precipitation.
A hydrodynamic separator causes sedimentation of solids in a radial flow regime characterized by secondary flows
The action of the separator causes the solids to enter the flow-calmed sludge trap located below the separator hopper. Above the separator chamber are the 4 filter elements. The rainwater passes through the four filter elements in an upflow process.
The height difference between inlet and outlet is only 25 cm. Since the system is installed under the traffic surface, it does not require any additional space on the property or in the road space.
The filter elements are easily replaceable. The system requires maintenance once a year. By using this rainwater treatment system, not only is infiltration prevented from blocking, but also groundwater, one of our most important resources, is protected in a sustainable and safe manner, even when the strictest specifications are applied.
