Abstract

This desalination system (S) desalinates waste water and seawater and comprises the following: a purification device (1) that allows waste water to pass therethrough and purifies the same; a first reverse osmosis membrane (2) that allows passed water (s5a) that was passed through the purification device (1) to pass causes the salt content of the passed water to be contained in and removed through first condensed water (s6a) and that generates industrial use water (s1); a first pre treatment device (3) in which the first condensed water (s6a) is subjected to any one pre treatment from between at least condensed filtration and nanofiltration membrane filtration; and a second reverse osmosis membrane (4) that passes first treated water (s7a) which was subjected to pre treatment by the first pre treatment device (3) that causes the salt content of the passed water to be contained in and removed through condensed water (s6b) and that generates industrial use water (s2).
