The system of purifying raw sewage using filters planted with reeds is ideal for purifying sewage from 35 to 2,500 eq./hab (equivalent population). Ideal for rural communities, the resulting purification of raw sewage complies with current European standards.
The system comprises two successive filter beds planted with reeds :
- The first one receives the raw water via a supply system equipped with a float-operated flush for pre-treating the sewage (removing matter in suspension and a part of the organic matter).
- The second one receives the clear water via a supply system fitted with a clear water float-operated flush, to ensure that the water is completely purified (organic matter, nitrogen, etc.).
It achieves a high degree of purification without the need for electrical power and does not require highly trained personnel.
