Abstract
Official abstract text for this publication.
A hollow fiber membrane module includes one pressure vessel, and at least one hollow fiber membrane element loaded in the pressure vessel. Each of the element includes a plurality of hollow fiber membranes each having openings at both ends, a bypass tube, and a supply port and a discharge port provided on one end side in a longitudinal direction. The supply port is in communication with inflow-side openings of hollow fiber membranes. The bypass tube is provided in the longitudinal direction of the element, has an inflow port at an end portion on a side of outflow-side openings of the hollow fiber membranes, and has an outflow port at an end portion on a side of the inflow-side openings of the hollow fiber membranes. The outflow-side openings of hollow fiber membranes are in communication with the inflow port, and the outflow port is in communication with the discharge port.
First claim
Opening claim text (preview).
1 . A hollow fiber membrane module comprising: one pressure vessel; and at least one hollow fiber membrane element loaded in the pressure vessel, each of the at least one hollow fiber membrane element including a plurality of hollow fiber membranes each having openings at both ends, a bypass tube, and a supply port and a discharge port provided on one end side in a longitudinal direction, the supply port being in communication with inflow-side openings of the plurality of hollow fiber membranes, the bypass tube being provided in the longitudinal direction of each of the at least one hollow fiber membrane element, having a bypass tube inflow port at an end portion on a side of outflow-side openings of the hollow fiber membranes, and having a bypass tube outflow port at an end portion on a side of the inflow-side openings of the hollow fiber membranes, the outflow-side openings of the plurality of hollow fiber membranes being in communication with the bypass tube inflow port, and the bypass tube outflow port being in communication with the discharge port. 2 . The hollow fiber membrane module according to claim 1 , wherein the at least one hollow fiber membrane element is two hollow fiber membrane elements, and in each of the two hollow fiber membrane elements, the supply port and the discharge port are provided on a side opposite to the other hollow fiber membrane element. 3 . The hollow fiber membrane module according to claim 1 , wherein the hollow fiber membrane module is for isotonic solution-pressurized membrane separation. 4 . The hollow fiber membrane module according to claim 1 , wherein the at least one hollow fiber membrane element includes a hollow fiber membrane wound body having the plurality of hollow fiber membranes helically wound around a central axis.
