Current desalination filters require about 1000 PSI to work. The idea using graphene is that the material could be designed with a pore size just large enough to pass water (3 angstroms) but would block everything else including dissolved salt from ocean water. Pressure required would be 100-200 PSI.
There is variant of this technology where pores are created by exposing graphene to high heat and pure oxygen, but exact pore size and placement can't be controlled.
Since Lockheed(MIC) owns the IP I wouldn't hold your breath.
