Graphene Filtration: A revolution in Desalination technology!
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.

Thorium liquid salts cooled nuclear reactors would offer basically free heat over night when electricity demand is low. This heat could be used for desalinization or electricity for making steel. Desalinization does have a basic problem – what to do with the salt? Store it on land and you have a waste problem….putting it back in the ocean cannot be done near the intake and the extra salt changes the environment of the ocean.

The salts and the excess energy from the reactors give you the basis for a chemical industry. Thus, you have a win-win. At the claimed 97% efficiency, it would be foolish just to throw it away.
Hope this helps.
Just a thought.

No, sorry, that didn’t help. I searched “desalinization salt waste” and received many hits…salt brine problem in middle east….MIT…..Scientific American…etc……lots more than my actual interest.
