摘要： The purpose of the invention is to provide a system which uses an osmosis membrane to obtain fresh water from salt-containing raw water such as seawater, wherein the system produces fresh water at lower energy consumption. According to the present invention, the system for producing fresh water includes: a forward osmosis membrane processing means for removing salt from raw water via a forward osmosis membrane to obtain permeated water in a solution having an osmotic pressure higher than that of the raw water; a separating means for separating the solute component of the high-osmotic pressure solution, the high-osmotic pressure solution containing the permeated water obtained by the forward osmosis membrane processing means and Na2HPO4 or ethylene carbonate as the solute component; a reverse osmosis membrane processing means for desalinizing the solution separated from the solute component by the separating means as raw water through a reverse osmosis membrane to obtain fresh water; a pump for supplying the raw water to the reverse osmosis membrane processing means; and a pipe for mixing the solute component separated and collected by the separating means, in the high-osmosis pressure solution supplied to the forward osmosis membrane processing means.
