Desalination

Desalination

More than 300 million people consume more than 86 million m3 of desalinated water every day. As water scarcity grows, the outlook for the desalination industry is good with an increasing need to provide clean and safe water.

The main concerns among the circa 150 countries now using a desalination process is that desalinated water production is energy-intensive and expensive. In fact, 50% of the 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:

  • It takes less energy than traditional membranes to produce the same amount of water.
  • More water can be processed before cleaning is needed, making the desalination process more efficient.
  • Preferential transportation of water between the graphene oxide planes results in high salt rejection.

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.
