Integrated in its urban environment with a compact footprint, the Xiamen plant daily discharge 300 000 m3 of highly depolluted effluent to the sea, thanks to nitrification – denitrification treatment through BIOFOR® technology.

 

The plant is the result of a fruitful collaboration between the city of Xiamen (Fujian province) and Degrémont, started in 1992 with the construction of a conventional primary treatment line, followed by another 100 000 m3/d primary treatment line through SEDIPAC 3D technology.
