Fattoria della Piana is an innovative dairy farm in the province of Reggio Calabria, whose main activities are cattle breeding and cheese production, in addition to a restaurant for guests and for educational activities. Alongside the system of constructed wetlands for dairy, milking parlour and domestic wastewater treatment, sized to treat about 100 m3/day, an anaerobic digester enables management of slurry and the serum recovered and their conversion into energy. CW produced biomasses will be integrated in the anaerobic reactor feeding mixture. The CW system is composed by 4 parallel lines, each with 2 stages, for a total of 8 HF CW beds with a net surface of 2200 m2.
