Filtration Chamber
Decentralised, efficient, low-maintenance removal of pollutants from rain water
The Funke Filtration Chamber is manufactured monolithically from a Funke DN 1000 Profile Pipe. The chamber’s main components include a tangential inlet, a vertical spiral lamella structure, a flow separator, a filter unit and a circumferential fully slotted drainage pipe. The Funke Filtration Chamber is suitable for a catchment area of up to 600 m² (DIBt/German Institute for Building Technology). Including its cover slab, the system has a total height of 3.2 m. The height offset between inlet and outlet is approx. 1.0 m; the outlet depth is at approx. 2.0 m. The filter unit consists of D-Rainclean® filter media. The rainwater is diverted using a circumferential fully slotted drainage pipe held inside a gravel sleeve.
Pollutants are retained
As the storm water runoff water passes through the Filtration Chamber, more than 90% of the sediment as well as both dissolved and undissolved pollutants are retained within the chamber’s different filtering sections. The result: The storm water runoff coming out of the chamber is compliant with the inspection requirements of Germany’s Federal Soil Protection Ordinance (BBodSchV) and may drain into the ground water.
The advantages in practice:
- Robust, sturdy and long-lasting
- Lightweight design
- Easy inspection and maintenance
- High efficiency levels
