Reed bed geokit
Strongly concerned with sustainable development, Cultisol has been working for a long time on improving water sanitization and filtration techniques. In collaboration with Sint and Epur Nature (study bureau specialized in reed bed filtration systems), it launched the patented Autoepure Geokit for reed bed water filters (patent n. FR0757890). It is an optimized alternative inspired by large-scale wastewater treatment reed bed filter systems and traditional purification methods such as sand filters. This reed bed filter is a watertight basin with a "bed" of filtering granular material, where reeds are planted. The improvements made to this system were mainly focused on oxygenation, hydraulics as well as on the distribution of the effluent over the filtering bed. Autoepure reed bed filter is so far the only kit that can be used for these filtration systems. It can be custom made. It includes an EPDM geomembrane, puncture resistant geotextiles, a root barrier, a watertight cap flange and an adhesive flexible flange.
