Aerated wetland for a hotel in Antwerp, Belgium

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. 

Balhall: A two stage, 185 m2,Aerated saturated vertical flow reed bed system treating 5 m3/d of settled, secondary sewage.

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.

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.

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).

The two stage reed bed system at Aumont (500 PE), in the French Jura mountains meets stringent discharge standards in phosphorous removal through a third stage filtration with reactive media

Two vertical flow wetlands. One is a circulation system treating the pond water. The other treats the wastewater from the outside toilets
