3P Filter column

Integrierte Filter

Operating principle

The rainwater flowing into the concrete shaft is dammed up to the height of the base of the filter column and then flows evenly through the cylindrical filter surface from all sides.

The cleaned rainwater flows inside the filter column via the outlet to the outside. The volume between the base of the column and the concrete wall of the surrounding shaft serves as a sludge and sand trap.

3P filter column for connectable roof areas up to 9,000 m².

The 3P filter column is used to clean rainwater from roof areas so that it can then be collected in a cistern, allowed to seep away or discharged into a receiving watercourse. The filter column, which is positioned in the middle of a prefabricated concrete shaft, is equipped with a stainless steel 5-shaft twill weave. With a mesh size of 0.39 x 0.98 mm, particulate pollutants can be safely removed from the rainwater, which is then available for further use. The dimension of the inlet and outlet nozzles as well as the screening area is measured according to the connected area size.

Advantages:

  • Connectable roof areas up to 9,000 m²
  • Max. flow rate up to 270 l/s
  • high filtration and retention of pollutants
  • Compact system with high operational reliability
