A low-energy forward osmosis process to produce drinking water

Forward osmosis (FO) represents a tremendous and untapped opportunity with the potential to solve the global water crisis. The biggest challenge facing the application of FO technology is the economical separation of drinking water from its draw solution. Leveraging advances in nanotechnology, we he...
