Japanese Patent JP4973822

B1

PROBLEM TO BE SOLVED: To provide a seawater desalination system which can produce drinking water from seawater, increase industrial water and attain inexpensive water desalination cost.SOLUTION: The seawater desalination system S for obtaining industrial water and drinking water from seawater and sewage water, includes an MBR1 which eliminates active sludge from the sewage water and purifies the sewage water, a first RO membrane 2 which eliminates salt from the water transmitted through the MBR 1 so as to be included in first concentrated water s6 and generates industrial water s1, a UF membrane 3 which transmits the seawater and eliminates particles in the seawater, a second RO membrane 4 which eliminates the salt of treat water s5b transmitted through the UF membrane 3 so as to be included in second concentrated water s7 and generates drinking water s2, a stirring device 5 which stirs the second concentrated water s7 eliminated at the second RO membrane 4 and the first concentrated water s6 eliminated at the first RO membrane 2, and a third RO membrane 6 which eliminates the salt of a mixed liquid stirred at the stirring device 5 so as to be included in third concentrated water s9 and generates industrial water s3.
