BIONUT2 FILTER UNIT ONLY – 4 TO 20 PE

The lines in the BIONUT® range are lines for treating domestic wastewater from individual homes or groups of dwellings. These devices support the intermittent operation of second homes and do not require any energy input. The treatment is based on the biological compact filter technique which reproduces the natural purification of water through the soil. These sectors are made up of an all-water pit ensuring the pretreatment of the effluent and a compact filter made from hazelnut shells ensuring the biological treatment.
