Interesting step forward by researchers at the CSIRO team in Sydney in efforts to develop affordable desalination technology.
Ultimately, the potential application for affordable large scale desalination could be one of the biggest global technological breakthroughs in addressing social, economic and environmental issues.
In the more immediate future, desalination does have application in support of industrial processes, decontamination as well as environmental remediation. It could also play a role in addressing water infrastructure issues closer to home.
Graphene, the much-hailed wonder material, may be the solution to the world’s water crisis. One in nine people around the world do not have access to clean, safe water close to their homes and at least 2 billion people are forced to use a contaminated drinking water source. First developed by scientists at the University of Manchester in 2004, graphene, an ultra-strong material composed of a single layer of carbon atoms, has been tipped for many uses from hair dye to super long-life batteries. But one of the material's most exciting properties may be its ability to filter out even the tiniest impurities in water. Researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Sydney have recently found a way to turn ordinary cooking oil into graphene to create a much more effective filter than standard methods.
