The resultant elution may include a substantially pure solution comprising the desired molecule.

A water filtration module includes filtration elements, each formed from a bundle of hollow fibers. In each element, the end portions of the fibers are included in the coating blocks that do not close them, and a longitudinal hollow tube is arranged at the center of the bundle, so as to open on either side of the coating blocks. Each element includes a cap attached around the lower coating block providing a chamber in hydraulic communication with the hollow fibers and with the central tube. The set of elements are assembled removably in a housing of the module, such that an upper permeate collection chamber of the module is in hydraulic communication with the hollow fibers and the central tubes of each of the elements.

There is provided a film separation device 1 equipped with a treatment tank 2 receiving a liquid to be treated, a film unit 3 to be immersed in the liquid to be treated, and a guide mechanism 4. The guide mechanism 4 is composed of holding sections 14 and a guide section 15. The holding sections 14 are provided on a side section of a film cassette 5 constituting the film unit 3, and the guide section 15 is fixed to the treatment tank 2. The guide section 15 has a tank-wall fixed section 15a, an upper extension section 15b, a held section 15c, a lower extension section 15d, and a tank-bottom fixed section 15e. When fixing the film unit 3 to the treatment tank 2, the holding sections 14 are fitted to the held section 15c, thereby guiding the film unit 3 to a predetermined position in the treatment tank 2.

A hollow fiber membrane module includes: a tubular case; a hollow fiber membrane bundle; and a pair of sealing and fixing portions, in which an outside-membrane channel that passes by an outer wall of each of the hollow fiber membranes and an inside-membrane channel that passes through the hollow inside of each of the hollow fiber membranes are formed, moist air flows through the outside-membrane channel, and dry air flows through the inside-membrane channel, whereby moisture in the moist air is supplied to the dry air by a membrane separation effect of the hollow fiber membranes, wherein a plurality of spaces are disposed between the case inner wall and the hollow fiber membrane bundle, and a restriction portion that restricts the hollow fiber membrane from entering into the spaces is partially disposed between the hollow fiber membrane bundle and each of the spaces.
