Chinese Scientists Develop New Method to Extract Water from Frozen Oceans in Winter
Shi Peijun, the head of the research team, stated that the salinity of the water extracted from ice is less than 0.2%, which falls within the safe drinking water threshold. The cost of extracting the salt is approximately 4 yuan per ton (0.5 USD).
A review conference organized by the Ministry of Education concluded that the technique has matured and meets the basic requirements to begin large-scale testing before entering mass industrial production.
The city of Tianjin in northern China is planning to build a demonstration project to utilize water extracted from ice for irrigation of various crops.
Shi, who is also the vice president of Beijing Normal University, mentioned that processing winter ice near the Bohai Sea could yield 30 billion cubic meters of fresh water annually. This amount is comparable to the water flow from the Yellow River into the Bohai Sea each year.
