摘要： 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.

摘要： In a method for producing hollow fiber membranes which comprises melt kneading a mixture comprising polyvinylidene fluoride and an organic liquid or a mixture comprising polyvinylidene fluoride, an organic liquid and an inorganic fine powder, extruding the kneaded mixture to form hollow fibers, and extracting the organic liquid or the organic liquid and the inorganic fine powder from the hollow fibers, which includes the steps of drawing the hollow fibers before or after termination of the extraction and then shrinking the fibers. According to this method, it is possible to stably produce hollow fiber membranes having dense pores and having a high water permeation performance, excellent endurance and stain resistance, and which are suitable for filtration uses such as removal of turbidity of water.
