WETLAND TREATMENT SYSTEM

Material:
beds in linear high density polyethylene (LLDPE) for horizontal subsurface-flow wetland treatment through PVC connection pipe with rubber gaskets and deflector T, LLPDE level chambers with PVC inlet and outlet and rubber gaskets.

Application:
secondary or tertiary treatment of civil wastewater through horizontal subsurface-flow wetland system.

Use and maintenance:
in order to ensure the good operation of wetland systems, one must guarantee the proper functioning of the primary treatments (grease separator, Imhoff septic tank) and possibly of the secondary treatments installed upstream of the beds, checking deposits of solid material that could obstruct the distribution systems and accumulate in the soil in which the vegetation grows. During the laying operation, the beds should be placed so as to minimize the inflow of rainwater to the treatment system, creating small sidewalls and reducing the runoff, thus facilitating the growth of turf near the beds. Inspections on the level chambers (DD150FT) shall be carried out every three months with removal of weeds that could affect the development of the species selected for the treatment. Together with the purging interventions of the primary and possibly secondary treatment systems, the distribution pipes shall be additionally cleaned with a pressure wash system.

Installation:
please follow the underground installation instructions provided in the manual attached.
