Common hollow fiber membrane modules have a cylindrical shape, i.e., a bundle of fibers is cast in a cylindrical tube, which is commonly used for microfiltration. In this technique, the hollow fiber membranes need to be uniformly arranged at as high a density as possible, increasing the number thereof without the membranes being substantially in contact with other membranes, to increase the water treatment capacity per module. In order to make the hollow fiber membrane filaments arranged uniformly, two steps are required, namely, cutting the hollow fiber membrane filaments into uniform lengths, and setting mounting and dismounting hole positions at the pouring end to limit the positions of the hollow fiber membrane filaments. This approach is relatively complex.
