Compact filter BIONUT 4 to 20 PE

The systems in the BIONUT® range are designed to treat domestic wastewater from single-family homes or groups of dwellings. These systems can cope with the intermittent operation of second homes and require no energy input. The treatment is based on the compact biological filter technique, which reproduces the natural purification of water through the soil, and consists of an all-water tank for pre-treatment of the effluent and a compact filter made from hazelnut shells for biological treatment.
