A ten years old system treating the wastewater produced by a winery in Central Italy. Cecchi is a famous wine producer in Italy and the production is certified ISO14001; all the wastewater produced by the "bottling department", located in Castellina in Chianti, Province of Siena, is appropriately treated before to be discharged in a nearby stream by a multistage constructed wetland.
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.
