A graphene oxide coating technology听could give a third of the world鈥檚 population access to safe drinking water.听
The Centre for Process Innovation听has collaborated on a听three-year听project – GO Membranes – with G2O Water Technologies, Unilever and William Blythe to develop a scalable process to purify water for use in point-of-use water purification systems.听
Despite the UN’s declared Human Right to Water Policy, almost 30% of the world’s population does not have access to safe drinking water.听The development of membrane filters is critical to water-purification systems and a means of addressing the global challenges of poor water quality, pollution of aquatic surface water sources, and water scarcity.听听
Overcoming the inherent limitations of conventional membrane materials to purify contaminated water听at low cost while retaining high water flux is necessary.听G2O says its听coating technology has shown improved separation of contaminants versus听uncoated membranes.听听

Tony Jackson, Director of Formulation at CPI, said: 鈥淲e are delighted to have played our part in such an important project, which has the potential to address one of the world鈥檚 pressing problems 鈥� that around clean drinking water.听听听
鈥�By听developing听key improvements to existing technology, we have demonstrated that UK innovation can not only help people locally, but also in the wider world.鈥�听
Chris Wyres, CEO at G2O Water Technologies, said: 鈥淭he project has demonstrated the utility of G2O鈥檚 technology to transform the performance of membranes, reducing the cost and environmental impact of water treatment and providing a route to address the growing global challenge of water scarcity.鈥�听
