Graphene Sieve Water Filter Makes Seawater Drinkable a Healthy Research by University of Manchester

Graphene Sieve Water Filter

Graphene Sieve Water Filter Update: More than two-thirds of the earth is covered with water, about 96.5 percent of which is saline water that is unfit for human use. As a result, shortage of drinkable water is a common issue in many countries around the world.

Researchers at the University of Manchester have used a Graphene ‘Sieve’ to successfully filter salt from seawater to make it drinkable for the first time.

The Graphene Sieve Water Filter study, published on 3rd April in the journal Nature Nanotechnology, found that a graphene-based membrane was capable of blocking salt molecules, while letting water flow through its pores.

Millions of people living in low-income countries lack a reliable source of drinking water. As the impact of climate change increases clean water demand while reducing water supplies, wealthy nations have begun investing in developing new technologies to filter water.

What if, there was a portable device or invention of some kind that could make seawater drinkable? Fortunately, that might not just be a dream anymore as scientists have actually come up with a sieve that can remove salt from saline water.

Graphene Sieve Water Filter has been much discussed as a possible component in new filtration technologies, including desalination.

Professor Rahul Nair, one of the researchers said about Graphene Sieve Water Filter:

“This is the first clear-cut experiment in this regime. We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes.”

Previously, scientists based at Manchester’s National Graphene Institute had developed a graphene-oxide membrane and shown that it swells when waterlogged. Large molecules such as organic molecules and complex salts were blocked by the membrane.

According to the UN, 14% of the world’s population will be facing a shortage of water by 2025. However, if this invention does indeed works as proposed and could be effectively put to use around the world, then it has the potential to be a life-saving invention for humankind.
