Abstract: A reverse osmosis membrane apparatus has a plurality of high pressure vessels 12a and 12b in parallel with each other with respect to introducing passage 18 of clarified seawater obtained by subjecting raw seawater to sterilization and removal of relatively large foreign substances. The high pressure vessels 12a and 12b have first-stage reverse osmosis membrane elements 14a and 14b, respectively. Concentrated seawater subjected to membrane separation in the high pressure vessels 12a and 12b flows into a high pressure vessel 16.
