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.
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
Resolis: Two 200m2 horizontal subsurface flow wetlands operated in paralell treating 10m3/d of secondary sewage.
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.
Dufftown: An 800m2 surface flow reed bed, treating 650 m3/d of copper contaminated effluent from three distilleries.
Mayfield: A 2.1 hectare, 12 bed aerated horizontal system treating airport run off contaminated with glycol based antifreeze.
Orelle (French Alps): a 1200 m², vertical flow reed bed (French system) plus a 800 m² second stage unsaturated vertical flow reed bed for domestic effluent under cold climate conditions.
