Beautiful two stage French system treating the wastewater of a hamlet in the outskirts of Paris
One stage of reed beds fed with raw sewage assures primary and secondary treatment for 1200 People Equivalent, followed by a trickling filter for polishing and nitrification. A tertiary UV treatment enables a pathogens removal by 4 U log.
In 2001, IRIDRA managed the design of a constructed wetlands system for the wine-producing firm “Tenuta dell’Ornellaia”, Leghorn, Italy. The system consists of vertical flow constructed wetlands (SFS-v) as a first stage followed by a second SFS-h stage with recirculation to the first stage and then by a single FWS. It treats wastewater from the firm, which allows water to be reused for irrigation
Allenwiller : a 1700 m², vertical flow reed bed (French system) plus a 960 m² second stage unsaturated vertical flow reed bed filter, treating 495 m3/d of domestic effluent from three villages (1100 PE) in Alsace.
Recirculated vertical flow French system for 800 p.e. with polishing in a "natural" horizontal flow wetland
2-stage Vertical Flow Constructed Wetland for the treatment of raw domestic sewage (French system) for 1360 people-equivalent adapted to the local resources and climate with UV tertiary treatment.
Two constructed wetlands at Warsco Genk treat the run-off from 1 ha pavement and the cleaning water from a washing street for temporary units.
Dufftown: An 800m2 surface flow reed bed, treating 650 m3/d of copper contaminated effluent from three distilleries.
Wetland to treat run-off from deicing operations contaminated with high concentrations of glycol compounds and capable of handling peak flows and loading from winter storms.
