Abstract:
A housing ( 30 ) of a hollow-fiber membrane module ( 101 ) is so configured as to have a small-diameter part ( 3 B) having an inner diameter smaller than an inner diameter of a flow regulation cylinder ( 9 ) facing a part of the housing ( 30 ) on which a nozzle ( 8 ) is provided, and which is arranged on a lower side than a lower end of the flow regulation cylinder ( 9 ) in an axial direction of the hollow-fiber membrane module ( 101 ); or the flow regulation cylinder ( 9 ) is so configured as to have a small-diameter part ( 9 G) which has an inner diameter smaller than the inner diameter of the flow regulation cylinder ( 9 ) facing the part of the housing ( 30 ) on which the nozzle ( 8 ) is provided, and which is arranged on a lower side than the existing region of the flow regulation holes ( 10 ) in the axial direction of the hollow-fiber membrane module ( 101 ).

Claim (Index 1):
A method for filtering a raw liquid, comprising:\n (1) flowing the raw liquid into an end of a flow regulation cylinder in a hollow-fiber membrane module and filtering the raw liquid with a hollow-fiber membrane bundle along an axial direction of the hollow-fiber membrane module, wherein the hollow-fiber membrane module comprises:\n the hollow-fiber membrane bundle including a plurality of hollow-fiber membranes; \n a first bundling and fixing part at which the hollow-fiber membrane bundle is bundled and fixed in a condition that at least a first end part of the hollow-fiber membrane bundle is kept open; \n a housing having at least one nozzle on a side surface thereof nearer to the first end part and housing the hollow-fiber membrane bundle therein; and \n a flow regulation cylinder having a plurality of flow regulation holes and existing between the first bundling and fixing part and the housing to liquid-tightly fix between the first bundling and fixing part and the housing, \n wherein:\n (i) the housing is so configured as to have a small-diameter part which has an inner diameter smaller than an inner diameter of the flow regulation cylinder facing a part of the housing on which the nozzle is provided, and which is arranged closer to a side into which raw liquid flows than an end of the flow regulation cylinder on the side into which raw liquid flows in an axial direction of the hollow-fiber membrane module, and a second bundling and fixing part which bonds and fixes the hollow-fiber membrane bundle, wherein the second bundling and fixing part is disposed within the small-diameter part of the housing, or \n (ii) the flow regulation cylinder is so configured as to have a small-diameter part which has an inner diameter smaller than the inner diameter of the flow regulation cylinder facing the part of the housing on which the nozzle is provided, and which is arranged closer to a side into which raw liquid flows than the flow regulation holes in the axial direction of the hollow-fiber membrane module; and \n (2) flowing the filtered raw liquid out of the nozzle.
