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.
