BIONUT compact filter for 5 to 15 PE – reinforced range (CARIBBEAN zone)

BIONUT treatment is done in two steps:
• pre-treatment, carried out by the all-water pit
• the biological treatment, realized by the compact filter based on hazelnut shells.
Once out of the pit all waters, pretreated water arrives in the trough integrated in the tank. This flush feeds the distribution ramp to optimize the distribution of water on the filter surface. The water then percolates through the filtering mass consisting of hazelnut shells on which are fixed aerobic bacteria that will ensure the treatment of water. The oxygen supply necessary for the development of the bacteria is done by a ventilation of 100 mm. The treated water is then discharged through a drain or to the superficial hydraulic medium (subject to authorization).
