800m2 Twin Rainwater Filter

Rainwater filter for large roof areas. The Twin Filter can be installed in chambers underground or directly on the wall kept frost-free. Usually installed in standard 1000mm manholes. The filter could also be pre-installed in chambers prior to delivery to site. Due to its two step cleaning system, it has a high level of filtering efficiency, independent of flow rate. Due to the steep inclination of the filter cartridge the dirt is continuously cleaned away into the sewer. The cleaned water is collected in a tank and directed into the storage. The two step filtration system is a tried and tested proven technology.

Connection capacity for roof areas up to 800m². A bypass-installation can be used to connect to a bigger area.

  • Rainwater inlet: 2 x DN 100/ DN 150 (110mm/160mm OD)
  • Tank inlet: 2 x DN 100/DN 150 (110mm/160mm OD)
  • Outlet into sewer: 2 x DN 100/ DN 150 (110mm/160mm OD)

The filter has to be cleaned depending on the contamination 1 – 2 times during the year.

How it works

  1. Water is equally distributed across the two cascades.
  2. Cleaning occurs through the cascades with the largest dirt particles forced across the primary filter cascades directly to the sewer.
  3. Pre filtered water then flows over the secondary filter sieve (mesh size 0,65 mm), where the mesh structure washes any remaining dirt into the sewer.
  4. The clean filtered water is being absorbed into the middle tank and then directed through either connection into the storage tank.
  5. Dirt goes directly to the sewer through the shaft.
