The National Graphene Institute & LifeSaver
The National Graphene Institute (NGI), based at the University of Manchester, has recently entered into an 18-month research project with LifeSaver, a UK-based manufacturer of portable and reusable water filtration systems.
The aim of the project is to develop graphene technology that can be used for enhanced water filtration. The goal is to create a proprietary, patented, cutting-edge product capable of eliminating an even wider range of hazardous contaminants than currently removed by its existing high performance ultra-filtration process.
Graphene has emerged as a material with fantastic potential for water filtration and desalination in recent years, with researchers on graphene membranes at NGI leading the way.
By incorporating graphene into its existing water purification technology, LifeSaver hopes to reduce the sieve size of its hollow fiber filtration membrane from the current 15 nanometers to about 1-3 nanometers. At that size, LifeSaver products could remove a much wider range of contaminants, such as heavy metals, pesticides, certain chemicals and potentially even nuclear radiation, from drinking water supplies.
"The University of Manchester is the world-leading centre for graphene membrane development, and LifeSaver has the expertise in making a portable water filter. This is a great example of a collaborative project where we are trying to combine two independently developed technologies into one, to enhance the quality and availability of drinking water for those who need it most" said Professor Rahul Nair, project lead at the University of Manchester.
