Water Desalination Using Graphene based Membranes Receives Patent

Home / News / Water Desalination Using Graphene based Membranes Receives Patent

A process for water desalination using graphene based membranes has been patented.

Grafoid Inc., a global leader in the graphene products and applications market, announced today that the World International Patent Organization (WIPO) has published international application number PCT/SG2019/050021 covering a graphene-based membrane, specifically a free-standing graphene-based membrane, and a method of forming the same.

The invention relates to a graphene-based membrane which contains properties making it suitable for use in the forward osmosis (FO) process of water desalination.  Specifically, the membrane performs at least seven times (with respect to water flux) and three times (with respect to reverse salt flux) better than a commercial cellulose triacetate membrane in forward osmosis due to its smaller interlayer distance and resistance to swelling.

This significant patent application recognition underscores Grafoid’s close collaborative efforts with the National University of Singapore (NUS) and our other partners and further reinforces our commitment to the commercialization of graphene-based products and solutions.  Grafoid remains confident that, through close collaboration with our industry partners including the NUS, Focus Graphite and others, our products in development worldwide are at the forefront of technological breakthroughs and will have wide-reaching impacts on the water treatment and other important markets.

According to the industry research firm Future Market Insights, the reuse of water is absolutely essential and the water treatment market is poised to grow at a CAGR of 7.4% from 2017-2027. Read full article here.
