This discovery was released this week and confirms that it is possible to filter the salt, leaving the water clean and drinkable. In 2025, 14% of the global population is expected to suffer from water shortages, according to data from the European Union, which also point to the various climate changes as factors that can worsen the scenarios, as they lead to a rise in temperature and the scarcity of rain.
It was a group of British researchers who discovered a new way to filter salt from salt water with a kind of graphene-based sieve, this discovery may even allow conditions in several areas of the world, such as those that do not have access to water May be improved.
Graphene is a crystalline form of carbon, organized in a hexagonal network and was first identified at the University of Manchester in the year 2002. Since then, scientists have focused their work on the development of a low-cost sieve that would allow Desalination on an industrial scale.
This discovery was released this week, and was published in Nature Nanotechnoly. The researchers also explained that they have been able to restrict pore growth by coating the material with a resin compound, thereby preventing pores from ingress and thus filter the salt, leaving clean water and Drinking water.
Rahul Nair, head of the project, explained in a statement to the university that innovation is “a significant step and will open up new possibilities for improving the efficiency of desalination technology”.
“This is the first clear experience. We have also shown that there are realistic possibilities for expanding the described approach and mass producing graphene based membranes with the necessary sieve sizes”, he added.
However, it remains to be ascertained whether this solution is effective in practice. But it is already taken as a major breakthrough in desalination.
