The National Graphene Institute (NGI) of the University of Manchester and the UK-based water filter manufacturer LifeSaver have embarked on an 18-month research project to commercialize graphene water filters. This partnership is based on the research of NGI graphene membrane, which has the prospect of cheap and effective water treatment.
One of the many useful properties of graphene is water filtration at high flow rates. NGI research shows that graphene-oxide membranes can be used for inexpensive and easy water desalination. However, Rahul Nair, who will lead the project at the University of Manchester, said the technology has not been commercialized.
Graphene oxide is the perfect screen
"It is our dream to make a portable water filter based on graphene, and the cooperation with LifeSaver will make this dream come true as soon as possible," he said. By combining NGI ’s graphene expertise with LifeSaver ’s core capabilities in the manufacture of portable water filters, Nair hopes that the project will create graphene-based filters to “improve the quality and safety of safe drinking water for those most in need. Availability ".
LifeSaver has produced portable water filters mainly for global travelers. The company's current hollow fiber membranes have an average sieve size of about 15 nanometers, which is small enough to filter out bacteria, microbial cysts, and viruses. Through this research collaboration, the company hopes to develop and apply market-leading water filtration products with a sieve size of 1-3 nanometers. This will be small enough to remove other common pollutants, such as heavy metals, pesticides, certain chemicals, and possibly even nuclear radiation.
Wesley Clarke-Sullivan, LifeSaver Product Manager, said: "For travelers who only use suspicious water sources for a short period of time, our current products pose very low health risks to them." As far as the community is concerned, certain elements in the water that we are currently unable to eliminate may end up adversely affecting their health. "
Although LifeSaver's portable and reusable water filters are ideal for outdoor sports enthusiasts, the company's mission revolves around humane work. For example, last year, after a series of earthquakes in Indonesia, LifeSaver dispatched more than 2,000 water purifiers to the scene, providing 11.5 million liters of safe drinking water.
The company was founded in 2007 after the British inventor Michael Pritchard created the world's first portable water filter that can remove the smallest known waterborne viruses. LifeSaver hopes to change the lives of 663 million people who currently do not have access to safe drinking water.
