PROBLEM TO BE SOLVED: To provide a low-cost water treatment system with a simple equipment constitution capable of uniformly feeding treatment water to the respective membrane modules.SOLUTION: In a seawater desalination system 100 comprising a reverse osmosis membrane module 10 composed of a reverse osmosis membrane 11 and a pressure container stored with the reverse osmosis membrane 11, where, by the feed of seawater into the reverse osmosis membrane module 10, permeable water and concentrated water are obtained by the reverse osmosis membrane 11 stored in the reverse osmosis membrane module 10, the seawater desalination system includes a module group 12 comprised so that the plural reverse osmosis membrane modules 10 are connected in parallel. By feeding seawater through the first seawater feed system B1 and the second seawater feed system B2 to the module group 12, the seawater is fed to each reverse osmosis membrane module 10. The first seawater feed system B1 and the second seawater feed system B2 are provided with liquid feed pumps 21, 22, 23 for feeding the circulating seawater to the module group 12.SELECTED DRAWING: Figure 1 |
