摘要：A water treatment device is provided with: a sub-reverse osmosis membranedevice (80S) having a primary casing (81) and a primary reverse osmosis membrane (86s)dividing the inside of the primary casing into a primary liquid passing part (91s) and aprimary permeation part (92s); a low pressure water feed pump (11) for pressure feedingseawater (SW) to the primary liquid passing part (91s) at a pressure lower than or equalto the osmotic pressure of the seawater; a main reverse osmosis membrane device (80M)having a secondary casing (81) and a secondary reverse osmosis membrane (86m) dividingthe inside of the secondary casing into a secondary liquid passing part (91m) and asecondary permeation part (92m); and a high pressure water feed pump (71) for pressurefeeding primary treated liquid (W1), which is the resulting product of seawater passingthrough the primary liquid passing pan (91s) and flowing out of the primary liquid passingpart (91s), to the secondary liquid passing part (91m) at a pressure higher than theosmotic pressure of the primary treated liquid (W1).
