Low Energy Evaporation and Crystallisation
Clean TeQ Water provided the engineering, procurement and construction of an evaporation and crystallisation plant in Xinjiang, China. It uses Clean TeQ Water’s EVAPX® technology and can process 15m3/h of feed water. The plant was finished in 2017 and put into operation at a coal to chemicals plant to achieve zero liquid dicharge (ZLD).
The plant removes calcium, chloride and COD from RO brine, and the distillate is reused as process water on site. Waste steam is used to power the EVAPX® plant which reduces the capital and operating costs.
