Gradiant, a technology company that specializes in industrial water solutions and innovations, is developing six brine concentration projects in China, two of which are in final stages of negotiation. Based in Boston, Massachusetts, USA, the company is working to secure the contracts with Shanghai Electric, a Hong Kong and Shanghai-listed enterprise and one of China’s largest mechanical and electrical equipment manufacturers.
The cooperation with Shanghai Electric follows an investment made by the Chinese manufacturer in Gradiant earlier this year. Prior to the investment, Shanghai Electric engineers fully vetted Gradiant’s award-winning Carrier Gas Extraction (CGE™) process. The company’s CGE technology produces fresh water from highTDS wastewater with significant cost advantages over traditional brine concentration or zero-liquid discharge (ZLD) technologies.
Gradiant is developing projects in China to treat power plant flue gas desulfurization (FGD) wastewaters and oilfield produced water with distillate capacities ranging from 500 to 36,000 cubic meters per day (m3/d). Gradiant has deployed similar projects in the USA, with capacities of up to 2,000 m3/d.
“In addition to power equipment, Shanghai Electric has a sizable desalination business as well as a strong understanding of water needs in China’s industrial sectors. They invested in Gradiant after determining the huge market potential of our desalination technologies in the region,” says Anurag Bajpayee, co-founder and CEO of Gradiant.
