Chengdu, China


With a capacity of 67,000m3 per day, the wastewater plant will treat industrial effluent from the refinery and a third of the wastewater, will be reused for cooling, saving the region's water resources.


Treatment lines

The facility will have one standard treatment line and one tertiary treatment line.

More than one third will be reused thanks to a treatment line made up of the largest ozonation unit ever installed in China (200kg/hr), a biological filtering system, an ultrafiltration stage, a reverse osmosis unit, and a sludge treatment facility. This treatment line will also receive treated rainwater.
