Beschreibung
Zusammenfassung:	An object of the present invention is to provide a fresh water generating apparatus that is capable of efficiently producing fresh water according to an intended use, while utilizing wastewater. Provided is a fresh water generating apparatus equipped with a seawater-treating reverse osmosis membrane device that produces fresh water from seawater by a reverse osmosis membrane, which includes: a mixing section that mixes wastewater as dilution water with a portion of seawater to be subjected to membrane treatment to produce mixed water; a first seawater-treating reverse osmosis membrane device that acts as the seawater-treating reverse osmosis membrane device to filter the mixed water; and a second seawater-treating reverse osmosis membrane device that acts as the seawater-treating reverse osmosis membrane device to filter the remaining portion of the seawater to be subjected to membrane treatment, in an unmixed state with the dilution water.
