The membrane rejected 99.99% of salt over the course of one month of use, providing a promising glimpse of a new tool for mitigating the drinking water crisis
Freshwater has become an increasingly precious resource. A major 2018 report warned that a quarter of the world’s population lives in areas that are under water stress. The climate crisis is worsening the situation by causing places that rely on snowpack for water to runoff earlier, an impact on display in California right now.
The new research published in the Journal for Membrane Science chronicles a unique way to desalinate water. The team designed a nanofiber membrane (a very good screen of extremely small things) which they say could turn seawater into drinking water in minutes.
