ABSTRACT:
Disclosed is a hollow fiber filter module comprising a cylindrical casing having a liquid introducing nozzle at least at one end portion thereof and having a bundle of hollow fibers disposed in the casing, and wherein one end portion of the bundle is enclosed by a hollow, liquid flow control member, and the liquid introducing nozzle has a specific unique structure in which the inlet opening has a larger diameter than that of the hollow of the nozzle at any portion thereof. This hollow fiber filter module can advantageously be used in the so-called external pressure type filtration on a large scale. By the use of this filter module, the external pressure type filtration of a liquid can advantageously be stably performed for a prolonged period of time with a high filtration efficiency.
