Estimating the term…
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.
A sea water desalinating method for desalinating sea water by way of filtration using a reverse osmosis membrane device, comprising carrying out a mixing step of mixing, as diluent water, biologically treated water produced by biologically treating organic wastewater into sea water to produce mixed water, and a mixed water processing step of feeding the mixed water produced by the mixing step to the reverse osmosis membrane device, at which the mixed water is filtered, thereby desalinating the sea water.
A sea water desalinating apparatus for desalinating sea water by way of filtration using a reverse osmosis membrane device, comprising a mixed water treatment part that mixes, as diluent water, biologically treated water, which is produced by biologically treating organic wastewater, into sea water to produce mixed water, and feeds the mixed water produced by the mixing to the reverse osmosis membrane device, at which the mixed water is filtered.
