QuantumSphere, Inc, a developer of advanced catalyst materials and clean-tech applications, has filed for a US patent on a forward osmosis water purification process that could reduce the energy costs of traditional desalination methods by 70%.

The process uses organic solutions to separate water from salt water or polluted water in an osmotic purification process. It uses a semi-permeable membrane to separate water from salt water into a special organic solution across the membrane. The diluted organic solution is then warmed to cause the specially formulated organic solute to drop out, leaving only fresh drinking water after a final purification step through activated charcoal.
