Zusammenfassung:An object is to provide a fresh water generating method that is capable of efficiently producing purified water, such as fresh water, from unpurified water, such as sea water. Provided is a fresh water generating method for generating fresh water by way of reverse osmosis membrane filtration, which includes mixing sea water with low salt concentration water having a salt concentration lower than sea water to produce mixed water, and subjecting the mixed water prepared by the mixing to reverse osmosis membrane filtration, thereby generating fresh water.
