Recently, a group of Manchester Institute of Science and Technology researchers made a major breakthrough in the graphene based desalination process. They were able to remove 97% of common salts in an energy efficient way. The current reverse osmosis desalination technology is energy intensive, and desalination plants’ capital costs are high. By the year 2025, 14% of the world's population will experience water scarcity, which makes this discovery very important. Moreover, graphene-based filtration technology could come to your kitchen very soon.
