Graphene sieve could make seawater drinkable

Posted on Tuesday, 4 April, 2017 | Comment icon 37 comments

The graphene sieve may be one of the most important inventions in years. Image Credit:
Scientists have come up with a new type of sieve that could bring clean drinking water to millions.
Developed by a team at the University of Manchester, the sieve is made from graphene - a 'wonder material' that is 200 times stronger than steel and can conduct both heat and electricity.

The breakthrough came after the researchers found a way to precisely control the size of the pores in the sieve, thus making it possible to use it to filter salt and harmful bactera from water.

"Realisation of scalable membranes with uniform pore size down to atomic scale is a significant step forward and will open new possibilities for improving the efficiency of desalination technology," said team leader Professor Rahul Nair.

"We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes."

so is not enough clean drinking water

How is that a relevant comparison. Clean drinking water is much more important to sustain life, without it most life will die;it's hardly like they'll be releasing salt into the air or anything that will actually causeharm to any form of life. In fact salt has healing properties when used in certain ways. I fail to see the disadvantage of this.

The bi product would have a use found.

there is a new device that when buried will produce clean water out of thin air. cost 134 dollars. it produces 11 gallons of water per day out of thin air.

New device? I posted about that idea years ago, right here. Plus for that to work it needs the right climate...and....its limited to a few gallons Cleaning sea water provides UNLIMITED water...

Agreed, being able to purify sea water is much moreefficient as it is one of the most (if not the most) abundant, easily accessibleresources on the planet.

My state goes through tons of salt for roads and the salt by product of this would be great to be a cheaper source of salt for the roads. The water produced with this would also be great for crop irrigation. I hope they use this method and it really works.

Taxpayers spend a ton of money on desalination plants that don't produce much except brackish ick that ends up being dumped back into the ocean. And that's not without its consequences. If they can throw this much of our money at these huge plants and they're not efficient, I don't have much faith that this is going to work. [More]

Isn't this a new method in the OP that would be less expensive?

What I read was this is the first experiment, they think there are possibilities, and they are hopeful. That's a far cry from having a solution to the problem of 14% of the world experiencing water shortages by 2025.
