Abstract: The present disclosure relates to a water recovery method and an FO draw solution that reduce the energy consumption required for water recovery, increase the osmotic pressure of a draw solution, recover the water from a DS mixed solution relatively easily, and reduce a solute that remains in the water, and simultaneously reduce fouling of the FO membrane. The water recovery method may include inflowing water into a draw solution by partitioning a feed solution including water and a draw solution, including a basic temperature-sensitive polymer and an acidic gas dissolved therein and having higher osmotic pressure than the feed solution, with a forward osmosis membrane.
