PURPOSE:To facilitate the fitting of an equipment to a piping line and exchange of a hollow yarn cartridge by providing the hollow yarn cartridge wherein both ends are bundled and fixed and it is supported with a supporting means, a casing, and a cover body provided with both an inlet of liquid to be treated and an outlet of permeating liquid. CONSTITUTION:Many hollow yarn 3' in which the upper ends are opened and the lower ends are closed and both ends are bundled and fixed are incorporated into a supporting means of the hollow yarn e.g. into a self-standing network casing 6 and a cone-shaped cap body 4 having a small-diameter projecting part 9 is connected with the bundled and fixed part 5 of the upper part and fixed. On the other hand, the aperture end of a casing 1 incorporated with a hollow yarn cartridge 3 is fitted to a cover body 2 which is provided with a first aperture communicated with an outlet 13 of permeating liquid in the center of its bottom wall and with a second aperture communicating with an inlet 14 of liquid to be treated. At a time of exchanging the cartridge, the casing 1 is separated by taking out a hand coupling 17 from the cover body 2 and the cartridge 3 is drawn out from the casing 1. Thereafter after inserting the new hollow yarn cartridge into the first aperture of the cover body 2, the casing 1 is fitted to the cover body 2.
