Desalination

  • G2O coatings have been tested on a wide range of commonly used membrane materials.

    In addition to resistance to fouling, pure water flux is increased by orders of magnitude.

    This reduces operating costs for existing desalination plants and potentially also make smaller scale micro desalination plants cost effective to operate.

  • The increase is due to preferential transportation of water between the graphene oxide planes which also results in high salt rejection allowing the creation of a new form of low pressure reverse osmosis system based on using an ultrafiltration membrane as a scaffold which is then coated with graphene oxide.
