The reverse osmosis membrane (20) is wound around the central tube (10) and covers each water-inlet hole (11) and forms a raw water flow channel. Two sides of the reverse osmosis membrane (20) are sealed by first and second water division bands (21) (22). The first water division band (21) and the central tube (10) form a first concentrated water-outlet (211). The first water division band (21) and the reverse osmosis membrane (20) form a second concentrated water-outlet (212). The second water division band (22) and the reverse osmosis membrane (20) form a first raw water-inlet (221). The second water division band (22) and the central tube (10) form a second raw water-inlet (222).
