Title:
FRESHWATER-GENERATING DEVICE, AND FRESHWATER-GENERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/155281
Kind Code:
A1
Abstract:
Disclosed is a freshwater-generating device that can stably and efficiently obtain fresh water. The freshwater-generating device comprises a seawater reverse-osmosis membrane device that obtains fresh water from sea water by means of a reverse-osmosis membrane. The freshwater-generating device is characterized by being provided with: a mixing unit that obtains a mixed water by mixing wastewater as dilution water with seawater; and a first seawater reverse-osmosis membrane device that, as the aforementioned seawater reverse-osmosis membrane device, filter-processes the aforementioned mixed water. The freshwater-generating device is further characterized by being configured in a manner so that the used water that is the wastewater obtained by the aforementioned obtained fresh water being used as service water is mixed as dilution water with seawater in the aforementioned mixing unit.
