PROBLEM TO BE SOLVED: To provide a novel and improved water recovery method and an induction solution for an FO method in which energy consumption necessary for water recovery can be reduced, an osmotic pressure of an induction solution can be easily made high, moisture can be easily recovered from a DS mixed liquor, a solute persisting in the moisture can be reduced, and fouling of an FO film can be reduced.SOLUTION: Provided is a water recovery method that is characterized by including a step in which a treatment solution including moisture, and an induction solution in which a basic property temperature sensitive polymer and a sour gas are dissolved, and an osmotic pressure is higher than that of the treating solution are partitioned by a forward osmosis membrane, and thereby the moisture is made to inflow to the induction solution. |
