Socogetra-exelio is proud to present its domestic effluent treatment system, now in operation, based on the two-stage reed filter principle (vertical flow).
But howdoesthe principle of reed filters work?
The effluent flows by vertical percolation through a mass of fine gravel. This filter bed allows suspended matter to be retained on the surface of the filter, where it accumulates.
The reeds that are planted in the filters have the particularity of forming a root tissue and a network of galleries that drain, bring oxygen and serve as a support for aerobic bacteria.
These bacteria have a role of degradation and mineralization of the organic matter, which then becomes assimilable by the plants.
