A vertical flow reed bed (French system) and a vegetated polishing zone (surface flow wetland)  treating 117m3/d of domestic effluent from a village with variable population

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.

The municipal centralised treatment plant (a classic activated sludge technology) for the wastewater produced by the municipality of Jesi (Ancona province – central Italy) has been upgraded in the year 2002, with the realisation of a new “nitrification-denitrification” compartment and a hybrid Constructed Wetland as polishing stage.

Large treatment wetland in the northwest of France, near the city of Le Mans,  treating 4000 PE and also large amounts of storm and drainage water. Zero surface water discharge in summer. 

The Badboot in Antwerp. Treatment of sanitary wastewater combined with wastewater from the swimming pool filters. FBA-type (aerated).

Full scale pilot plant treating CSO overflow in the Greater Lyon area.

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.

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).
