  • Publication number: 20170136414
    Abstract: According to one embodiment, a water treatment method is a method configured to use a working medium that includes a draw solution and a water-containing solution to be treated. The draw solution is a hyperosmotic solution which generates an osmotic pressure difference with water. The method includes generating a flux of a mixture of water and a draw solution by an osmotic pressure difference generated between a solution to be treated and the draw solution in an osmotic pressure generator compartmentalized by an osmosis membrane, transferring the flux of the mixture to a vaporization-separation unit, separating the mixture into the water and the draw solution by a pressure difference, and recycling the draw solution separated by the vaporization-separation unit.
