Claims

[Scope of utility model registration request]

A membrane separation means consisting of a plurality of disc membranes arranged in parallel at predetermined intervals in the axial direction of a hollow rotating shaft, which rotates integrally with the rotating shaft, is housed in a container, and A cleaning member that comes into contact with the membrane surface is provided,
The membrane-permeated water of the disc membrane is collected in the hollow part of the rotating shaft and flows out of the container, and the cleaning member removes the deposits deposited on the membrane surface of the disc membrane due to the membrane separation of the liquid. In a membrane separation device that scrapes the cleaning member by a method, a hollow portion large enough to allow insertion of the rotating shaft is bored at one end of the column supporting and fixing the cleaning member, or a hollow portion of such a size is provided. a protrusion or a protrusion that protrudes from an end member having a hollow portion of the size, and that the rotating shaft is inserted into the hollow portion with play, and that the other end of the support can be locked to the inner wall of the container; A membrane separation device characterized by being provided with a locking portion consisting of a protrusion.
