<p>PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module for reducing a pressure loss, even if a semipermeable membrane is used by a normal permeation method by using a high viscosity guiding solution.SOLUTION: The problem is solved by a normal permeation membrane treating hollow fiber membrane module for housing a plurality of hollow fiber membrane elements different in a hollow fiber membrane inner diameter in a hollow case, having a treatment water supply port and a discharge port of the guiding solution on one end of the hollow case and having a treatment water discharge port and a supply port of the guiding solution on the other end of the hollow case, that is, the normal permeation membrane treating hollow fiber membrane module for connecting the hollow case and the plurality of hollow fiber membrane elements so that the guiding solution flows on the inside of a hollow fiber membrane of the hollow fiber membrane elements different in the plurality of hollow fiber membrane inner diameters and treatment water flows on the outside of the hollow fiber membrane and connecting the plurality of hollow fiber membrane elements from the supply port side of the guiding solution in large order of the hollow fiber membrane inner diameters.</p> |
