物を吹き抜き目詰まりを解消することができる。The apparatus according to the present invention is constructed as described above, and if each filter frame is opened and brought into close contact with each other, a large high-pressure concentrating chamber in which a large number of filtration membranes are arranged side by side is formed. can do. Therefore, when the undiluted solution to be concentrated is supplied from the flow path provided in the filter frame while sending the bubbling air, the undiluted solution is dispersed throughout the concentrating chamber and filtered and concentrated by a large number of hollow fiber membranes arranged in parallel. And the filtrate separated by filtration is
From the hollow portion of the hollow fiber membrane, it is taken out of the machine through the take-out passage provided in the frame body, and the concentrated liquid in which the filtrate is separated is collected in the concentrating chamber. When the amount of filtrate discharged is reduced by such an operation, the stock solution in the concentrating chamber is sufficiently concentrated, and at the same time, the hollow fiber membrane is also clogged, so by opening the filter frame, The concentrated liquid can be dropped and taken out of the machine. On the other hand, a backwash fluid is sent to the clogged hollow fiber membrane from the flow path for removing the filtrate so that the clogged matter can be blown out and the clogging can be eliminated.
