Graphene breakthrough could help millions gain access to drinking water
New research at the University of Manchester claims to demonstrate that membrane material made from graphene has the potential to provide clean drinking water for millions of people who struggle to access adequate clean water sources.

Scientists at the university were responsible for isolating graphene in 2004. Now new findings from a group of scientists there have been published in the journal Nature Nanotechnology.

The Manchester-based group have developed graphene membranes that do not swell up when exposed to water. The pore size in the membrane can be precisely controlled which can sieve common salts out of sea water and make it safe to drink.

According to the United Nations, 14% of the world’s population will encounter water scarcity by 2025. This technology has the potential to revolutionise water filtration across the world, in particular in countries that cannot afford large scale desalination plants.
