Abstract: This repair method for a hollow fiber membrane module is a method for repairing a leaking section occurring in the hollow fiber membrane module, the repair method having a repair step for using a repair adhesive that hardens due to a composite curing function that comprises a moisture-curing function and a photo-curing function, to repair the leaking section.

Abstract: A hollow porous membrane including a porous membrane layer having a hole on an outer surface, wherein a membrane thickness of the porous membrane layer is 70 ?m or more, and the porous membrane layer has a region A, the correlation between a depth X (?m) and an average pore size Y (?m) of holes on a cutting plane at the depth X (?m) satisfies a regression line Y=aX+b in the case of cutting an outer surface of the porous membrane layer by the depth X (?m) in the region A, a slope a of the regression line is 0<a?0.08 and a coefficient of determination R2 of the regression line is 0.90 or more, and a, b, and R2 are determined by the following Equations (2?), Equation (3?), and Equation (4?), respectively.

Abstract: Provided is an inspection method of a hollow fiber membrane module and a repairing method capable of quickly identifying the position of a damaged membrane in the hollow fiber membrane module with a simple configuration.
