The £1m project led by G2O Water Technologies to develop new, graphene-based water filters has teamed up with the interdisciplinary team at [email protected], part of the University of Leeds.
G2O Water Technologies, a Manchester-based company has now taken its innovative, patented graphene oxide technology for comprehensive testing and evaluation by the Leeds tream.
This collaboration adds further weight to the company’s two Innovate UK-supported projects focused initially on oil/water separation and domestic water filters, totalling almost £2m in research and development expenditure. The ultimate aim is to develop the capability to treat water at a much lower cost and make it more affordable worldwide.
G2O will be working with the Public Health Laboratories within the School of Civil Engineering at the university to address real issues relating to water treatment in the water industry, including sieving of molecules or ions, removal of salts, oil, nuclear waste, dyes and other chemicals.
A pilot water treatment plant designed to test and develop the graphene water filters is scheduled for operation next year. If successful the filters could mean that all water on the planet could effectively be made drinkable.
Tim Harper, chief executive and founder of G2O Water Technologies, said: “We believe we are currently the only company transferring its graphene water filter technology from an R&D laboratory to an industrial setting to prove how it could help solve real-world water problems.
“This will involve working directly with water industry experts to understand their challenges in detail and evaluate how our graphene oxide membranes would complement their operations and help deliver what consumers need from their water supply.
“Our work with [email protected], along with having highly-experienced water industry professionals on our advisory board, means we are using the latest science and knowledge to address the right applications for the industry; helping treat water at a much lower cost and making it more affordable worldwide.”
Professor Martin Tillotson from the University of Leeds said: “[email protected] is one of the world’s leading interdisciplinary centres looking at various aspects of water treatment and we are happy to share our expertise with G2O. The university is committed to making a real and telling difference to the world around us by supporting industry in developing innovative products, tackling the challenges which society faces.”
Professor Tillotson said the joint project would involve developing commercially-viable water filtration membranes derived from G2O’s graphene technology that can be scaled-up for industrial application. The company is also exploring a number of partnerships with major consumer product manufacturers and energy companies in order to accelerate the process of bringing a graphene water filter product to market.
G2O’s patented technology works by creating low-cost printed graphene filters or by applying a graphene coating to existing membranes used in water filtration processes. This technique reduces the amount of energy needed to filter the water passing through the membrane by up to 50 per cent, increasing throughput of purified water while combating contamination and lowering the cost.
This new technology allows more water to pass through a membrane, therefore removing the need for, and expense of, electricity needed to run pumps and controls in existing water treatment plants. The technology wants to reduce the size and complexity of the plants, thereby potentially opening up the technology to less developed areas of the world.
Independent market research suggests that the global market for membranes used in water filtration to be worth more than $25bn.
