Desalination Of Sea Ice Feasible For Mass Production: Chinese Scientists

DALIAN, Liaoning, April 6 (Xinhua) — Sea ice seen as a disaster in northeast China’s Bohai Bay has been eyed as an important alternative freshwater source by Chinese scientists, as their latest research shows China’s desalination technology is feasible for mass production. “The salinity of desalinated sea ice can reach 150 mg/L, when 5 tonnes of sea ice is treated per hour through our lab equipment. The result is on a par with salt levels in many of China’s rivers,” said Chen Weibin, one of the researchers of the sea ice desalination program based in Dalian City, northeast China’s Liaoning Province.

Chen is also head of the Marine Environmental Dynamics Lab under the China Marine Environment Monitoring Center.

He said the program has attracted a group of scientists from the center as well as Beijing Normal University and Tianjin University.

China’s Bohai Sea and Yellow Sea this year were hit by the worst ice in 30 years lasting from early January to the middle of March.

“The salinity of the sea water in the Bohai Bay is 3,200 mg/L. However, when the water is frozen, the rate drops to 600-800 mg/L. Our equipment can further reduce the salinity,” said Gu Wei, a professor with Beijing Normal University, who is involved in the research.
