Two vertical flow wetlands. One is a circulation system treating the pond water. The other treats the wastewater from the outside toilets
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
Bauduen : a 2-stage Vertical FLow reed bed filter (French Design) for the treatment of domestic effluent from a village with variable population. A UV tertiary treatment ensures pathogens removal for protection of the bathing area in the lake downstream.
Saint Bonnet le Froid : a 900 m², vertical flow reed bed (French system) plus a 600 m² second stage unsaturated vertical flow red bed for the treatment of domestic effluent from a village with variable population.
