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.

An educational wetland of 30 PE treating the sanitary wastewater of a toilet building.

Two stage vertical flow wetland with recirculation. The system treats the wastewater from the ecological office building. The treated wastewater is reused for toilet flushing.

2-stage vertical flow reed bed filter treating raw domestic sewage (French system) with a capacity of 650 P.E. Treated effluent goes through a filtering ditch and is rejected into the river Bourdic.

 

Wastewater treatment plant for 1250 p.e., in a very touristic site in the south of France, separative sewerage system, constructed in 1998.

“French sytem” treating raw unsettled sewage in a 2 stage vertical flow reed bed filter without electricity

Treatment of aerobically stabilized sewage sludge from an activated sludge plant (“extended aeration”) – 13 000 p.e.

Resolis: Two 200m2 horizontal subsurface flow wetlands operated in paralell treating 10m3/d of secondary sewage.

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).
