Nanoporus Graphene Takes Another Step Toward Water Desalination Process

About 18 months ago, I wrote about an MIT project in which computer models demonstrated that graphene could act as a filter in the desalination of water through the reverse osmosis (RO) method. RO is slightly less energy intensive than the predominantly used multi-stage-flash process. The hope was that the nanopores of the graphene material would make the RO method even less energy intensive than current versions by making it easier to push the water through the filter membrane. The models were promising, but other researchers in the field said at the time it was going to be a long road to translate a computer model to a real product. “Manufacturing the very precise pore structures that are found in this paper will be difficult to do on a large scale with existing methods,” said Joshua Schrier, an assistant professor of chemistry at Haverford College. However, Schrier also...
