The present invention relates to a hollow-fiber membrane module. The hollow-fiber membrane module comprises: a housing part having a first fluid inlet and a first fluid outlet, and a second fluid inlet and a second fluid outlet; and a hollow-fiber membrane bundle comprising a plurality of hollow-fiber membranes, and disposed inside a housing such that a first fluid flows toward the inside of the hollow-fiber membrane and a second fluid flows toward the outside of the hollow-fiber membrane, wherein the hollow-fiber membrane bundle further comprises a porous tube of which both ends are blocked and which has a plurality of pores on a lateral side thereof. Since a region which the fluid flowing toward the outside of the hollow-fiber membrane bundle is hard to pass through is removed, the hollow-fiber membrane module enables the fluid to uniformly flow therein. Accordingly, even though the hollow-fiber membranes are accumulated at a high density, the performance of the hollow-fiber membrane module can be maximized. |
