Absorbing Bed Vertical Flow Phytodepuration System

Description of System.

The treatment process consists of a wastewater pre-treatment stage (e.g. static degreaser, Imhoff tank) and a natural biological depurative stage (secondary treatment) carried out by a sub-superficial vertical flow phytodepuration system (vertical liquid flow) made up of a watertight tank filled with aggregate material whose surface is covered in vegetal material consisting of macrophyte.

The wastewater is fed discontinuously into the top by means of a submersible motor pump controlled by an electric control panel with pause and work timers.

The wastewater percolates slowly through the bed and is conveyed towards the collection system at the bottom. The vertical flow phytodepuration system promotes the creation of aerobic conditions inside the medium, unlike horizontal flow absorbing trays or beds where the water level is slightly below the surface.

This type of wastewater treatment is easy to manage, is aesthetically pleasing, has low energy consumption, is environmentally friendly and can be completely integrated with the surrounding environment. It is designed to guarantee maximum evapotranspiration.
