We are specialized in the following ecotechnologies:
Reed bed sewage sludge treatmentSewage sludge treatment by artificial wetlands
Domestic sludge is dispersed onto reed beds. The reed plants grow through the overlying sludge and develop numerous roots in the substrate. This leads to a forced dewatering and mineralization of the sludge. The dewatering is driven by evapotranspiration and particularly by a drainage system on the bottom of the sealed reed beds (polyethylene liner).
The sludge volume declines to about 10 % of the initial volume. Usually the reed beds work for a period of 8 to 12 years without sludge removal. The resulting product of the dewatering is an earthy organic material. The sludge humus can be used for further composting, for fertilization, for thermal recycling, for recultivation, gardening and landscaping.
