Abstract
A hollow fiber membrane module includes: a hollow fiber membrane bundle; a housing formed with a port for allowing a cleaning gas for the hollow fiber membrane bundle to inflow therethrough for accommodating the hollow fiber membrane bundle; and a diffuser having a receiving surface for receiving the cleaning gas having entered through the port, the receiving surface being formed with diffusion hole for diffusing the cleaning gas to the hollow fiber membrane bundle in housing. The diffuser includes a partition dividing a space under the receiving surface into an inner space and an outer space surrounding the inner space and permitting the cleaning gas having entered through the port to flow thereinto. The diffusion hole is arranged to allow at least a part of the cleaning gas flowing in the outer space to diffuse from the inner space to the hollow fiber membrane bundle.
