It’s Now Possible to Turn Seawater into Drinking Water

Researchers at Manchester University have made a sieve that can remove salt from seawater and turn it into drinking water

It’s Now Possible to Turn Seawater into Drinking Water

Caspian International News Agency– According to a report by BBC World, this graphene-based sieve can help millions of people around the world to access clean water.

This sieve, which researchers have called a “shell”, is made of graphene oxide which has a high ability for  filtering salt

Before this, producing a graphene filter on an industrial scale was difficult.

Dr. Rahul Nair led the research team for this achievement, and the journal Nature Nanotechnology published a comprehensive report of it.

According to this report, graphene is made of  a single layer of carbon atoms arranged in a hexagonal lattice. It was isolated and characterised by a University of Manchester-led team in 2004for the first time.

Its unusual properties, such as extraordinary tensile strength and electrical conductivity, have earmarked it as one of the most promising materials for future applications. .

The United Nations predicts that by 2025, nearly 14 percent of the world’s population will face water shortage.

As the global warming  continues and affects urban water resources, wealthy modern countries are investing in desalination technologies.

Desalination technologies around the world use polymer-based membranes.

In the next step, graphene oxide is going to be tested against other products in the market.

This method will pave the way for cheap water filters.
