Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.

A quarter of the world’s population across 17 countries are living in regions of extremely high water stress, a measure of the level of competition over water resources, a new report reveals.

Experts at the World Resources Institute (WRI) warned that increasing water stress could lead to more “day zeroes” – a term that gained popularity in 2018 as Cape Town in South Africa came dangerously close to running out of water . . .

 . . . Although the US did not have high levels of water stress overall, a handful of states – including New Mexico and California – were found to be facing significant strains on their water supplies that will only intensify with global heating.

Distilling water using the sun’s rays . . . a University at Buffalo startup has found a quick way to do it . . . and it could transform how potable water gets to people in developing countries or in areas stricken by natural disasters like earthquakes or hurricanes.

The university’s Sunny Clean Water startup said its method is nearly three times as fast as the industry standard . . . 

. . . The process uses a floating solar still and a specially-engineered carbon-based cloth to capture, desalinate and purify as much as a liter of water every three hours in a prototype developed by UB associate professor of electrical engineering Qiaoqiang Gan, Singer and other university electrical engineering students.
