Graphene Membranes Superpermeable to Water

Dr Max writes "Not only is graphene the strongest, thinnest and best conducting material known to man, it is now shown to have superpermeability with respect to water as well. This allows a membrane made with graphene to pass water right through it (PDF), while another atom or molecule (even helium) gets blocked. 'The properties are so unusual that it is hard to imagine that they cannot find some use in the design of filtration, separation or barrier membranes and for selective removal of water,' said one of the researchers."

Now we know what the water receptacles in Dune were made of.

Fresh water?

So you could pass thru i.e. ocean or contaminated water and get fresh, drinkable, pure water on the other side? If that could scale could be great.
