Abstract

PURPOSE:To prevent the clogging of a passage between membranes and to increase the permeation rate of permeated water by interposing a corrugated spacer having a meandering rolling strip between the membranes in the title spiraled membrane module to be used for a membrane separator. CONSTITUTION:A water collecting pipe 1 is pierced with openings 1a for allowing the inside of the pipe to communicate with the outside, and a separation membrane 3 is wound on the outer periphery through a corrugated spacer 2. The separation membrane 3 has a bag shape, the water collecting pipe 1 is wrapped up in the central part 3a, and the non-central parts 3b and 3c are laminated, and the laminate is wound on the periphery of the water collecting pipe 1. A mesh spacer 4 is inserted into the bag-shaped separation membrane 3. The spacer 2 is corrugated, continuously extended, and provided with a meandering rolling strip. Raw water is passed between the separation membranes 3 along both surfaces of the spacer 2, permeated through the separation membrane 3 on the way, and sent into a permeated water passage 5. The permeated water flows in the passage 5, enters the water collecting pipe 1 from the opening 1a, and is discharged from the module.
