Graphene has been making many appearances in science lately, owing to its unique physical properties. Today, it’s making headlines in a rather unexpected field of research: water treatment. Researchers from the University of New South Wales (UNSW) Sydney, working together with Sydney Water, have created a world-first graphene filter that can remove 99% of the natural, organic matter left behind by conventional treatment of drinking water. The team is now working on scaling up their technology.
