Leak test method for hollow fiber membrane module |
| abstract |
【Task】 Provided is a method for accurately detecting a defect of a hollow fiber membrane module without wetting the hollow fiber membrane module in a dry state and without leaving a substance harmful to the human body. [Solution] A leak test method for a hollow fiber membrane module in which the moisture content of the hollow fiber membrane is 100% or less, wherein an aerosol containing fine particles composed of an inorganic salt having a particle diameter of 0.05 μm or more and 3 μm or less is aerated, and the inorganic salt A leak test method for a hollow fiber membrane module, wherein the total amount used is 100 mg or less per 1 m 2 of the membrane surface area, and the leak is detected by measuring the transmittance of the fine particles. [Selection figure] None |
