HOLLOW FIBER MEMBRANE MODULE

摘要

The present invention relates to a hollow fiber membrane module comprising: a hollow fiber membrane; a support portion provided at the lower end of the hollow fiber membrane; a collector provided at the upper end of the hollow fiber membrane; an extension pipe extended upward from the support portion; and an air diffusion unit for diffusing air to the upper region of the hollow fiber membrane, spaced from the upper part of the support. Therefore, it is possible to inhibit contamination of the upper region of the hollow fiber membrane.
