HOLLOW FIBER MEMBRANE MODULE AND UNIT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module whose housing is hardly warped by air bubbling though the accumulation rate of the hollow fiber membrane module can be made high and in which entanglement of hollow fiber membranes is not generated and to provide a unit of the hollow fiber membrane modules. SOLUTION: This hollow fiber membrane module is provided with the housing 2 which has <=25 mm the maximum width in the direction crossing the longitudinal direction of the hollow fiber membrane 3 at right angles on the cross section perpendicular to the longitudinal direction of the housing 2 and the maximum amount of which to be warped is made to be <=1% of the distance between two housings when the warp is measured by supporting the housing 2 on the both end parts so that the mass of another housing 2 is not imposed on the housing 2 to be measured and hanging the weights of 0.05 kg at the intervals of 5 cm from one end to the other end of the housing 2 to be measured.
