HOLLOW FIBER MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module capable of reducing lowering of flux due to breakage or hydrophobization of the hollow fiber membranes. SOLUTION: This hollow fiber membrane module 1 is provided with a membrane bundle 20 formed by bundling multiple hollow fiber membranes 10; a cylindrical body 30 housing the membrane bundle 20; fixing parts 40, 50 fixing at least one end part of the membrane bundle 20 to the cylindrical body 30; and a raw water flowing out nozzle 34 letting the raw water flow out of the vicinity of the fixing part 40. Raw water supplied into the cylindrical body 30 passes from the outside of the hollow fiber membranes 10 to the inside thereof. A soft potting part 42 has at least one groove 43 on a face contacting with the raw water. COPYRIGHT: (C)2007,JPO&INPIT
