Dialysis fluid regeneration by forward osmosis: A feasible option for ambulatory dialysis systems

In forward osmosis (FO), water is drawn from the feed solution to dilute a more concentrated draw solution across a water permeable, but solute impermeable membrane. Recently, there has been a great interest in the possible appli­cations of FO including osmosis pumps for drug delivery, water desalination and the hy­dration bags made by Hydration Technologies, Inc., Oregon.
