The main concerns among the circa 150 countries now using the process is that desalinated water production is energy-intensive and expensive. In fact, 50% of cost of the water is energy costs.
Now, the economics of delivering desalinated water could be radically changed with the introduction of G2O graphene oxide-coated membranes to a plant.
The membrane’s surface design means more water can be processed before cleaning is needed so making the desalination process more efficient.
The properties of the G2O technology also mean that it takes less energy than traditional membranes to produce the same amount of water. It then becomes possible to consider using renewables, such as solar and wind, to reduce the energy costs further.
By adopting the G2O graphene oxide-coated membrane, desalination plant operators have the potential to build smaller and more efficient units and increase their ability to improve water supply to cities and remote locations.
