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
Vertical flow reed bed filter (French system) followed by a trickling filter and a treatment with apatite treat the pollution of raw domestic sewage. Capacity : 1500 p.e. Vegetated effluent discharge area before final reject into the small river "Merderic".
Llanfair PG: A 440 m2, vertical flow reed bed treating 55m3/d of domestic effluent from a residential education centre.
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.

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
"Zero Emission" would be the general goal for sustainability. Especially for industrial production. Tertiary treatment with constructed wetlands may be a proper solution for closing the loop. The new treatment wetland at Changshu Advanced Materials Industrial Park, Haiyu Town, Jiangsu Province, China, is not only reclaiming water. It is a stepping stone for humans searching nature and for endangered species within a widely industrialized zone. Designed as a beautiful park it provides recreational functions and serves as buffer stripe between chemical industries and urban areas.
The wetland visitor center with its terraces on the roof and near the water level reveals a stunning new perspective. Intersted visitors will be given looks inside of the wetland when entering the exhibition on the first floor. Accomplished with a water laboratory and wetland control room the Changshu AMIP wetland center is a perfect place for training and dissemination of environmental solutions.
