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
Pouembout : a 250 p.e. reed bed filter was created to replace a deficient waste stabilization pond.
20 years old French system serving 200 p.e. in the Lyon area
Intensified (aerated) wetland for wastewater treatment of 800 employees at the administrative center of a mining company, situated near Belo Horizonte, Brazil.
Conception: 2 Septic Tanks for pre-treatment, aerated wetland as main treatment and horizontal flow constructed wetland post treatment.
Wetland project and execution by Rotária do Brasil, Landscaping only execution by Rotária do Brasil.
Balhall: A two stage, 185 m2,Aerated saturated vertical flow reed bed system treating 5 m3/d of settled, secondary sewage.
Client: Galten Municipality
Location: Skovby, Denmark
Established: 1995
Number of basins: 8
Sludge type:Activated sludge
Sludge volume: 185 tonnes DS/year
PE, amount: 12,000
Castelluccio is one of the best hotspot of Central Italy, with its spellbound village and the great plateaus at 1400 m a.s.l. in the Sibillini mountain park. The new Constructed Wetland will treat the wastewater of Castelluccio village and tourism facilities, that progressively shift from less than 50 persons during winter up to 1000 or more persons during summer. The current treatment plant is inadequate to support this great variation. The new multistage CW system is constituted by a French scheme system of 1800 m2 followed by two parallel free water-pond system as polishing stage and recreational amenity (the pond will hold several rare aquatic plants typical of the Castelluccio plateau).
Resolis: Two 200m2 horizontal subsurface flow wetlands operated in paralell treating 10m3/d of secondary sewage.
Hollange : a 432 m², vertical flow reed bed (French system) plus a 288 m² second stage unsaturated vertical flow filter, and a 1200 m² vegetated polishing zone treating 102 m3/d of domestic effluent.
Metz –park of the Seille : collecting and treating stormwater from an adjacent new housing development area inside a 20 ha urban park and renaturation of the river Seille, flowing along the park.
