Graphene is a revolutionary carbon material that is one atom thick and will find application in many areas. We have invented a form of graphene, Graph Air, that is uniquely suited to filtering compounds from water through membrane distillation.

Unlike normal water filters, Graph Air can filter out extremely toxic chemical compounds while allowing pure, pH neutral water through. It has narrow channels through which smaller water molecules can pass, but larger dissolved molecules and solvated ions are blocked. All while dealing with high concentrations of acids or alkalines that rapidly destroy other filtering membranes.

Graph Air is showing resistance to the biofouling that plagues current technologies, while delivering a higher flux than polymer membranes in the same application.
