Membrane cartridge in immersion type membrane separation apparatus

1. A membrane cartridge in an immersion type membrane separation apparatus, being a membrane cartridge in an immersion type membrane separation apparatus composed so as to form passages mutually by disposing adjacently in parallel, with a filtration membrane being disposed on a surface of a membrane cartridge main body as a filtration plate main body by joining at peripheral edges,

wherein selvages larger in thickness than the membrane cartridge main body are formed at both sides of the membrane cartridge, and a header forming part is formed on one selvage, and a guide hole is formed in other selvage relatively, and the header forming part and the guide hole of the membrane cartridge disposed adjacently by varying the direction mutually are formed to communicate and connect with each other.

2. The membrane cartridge in the immersion type membrane separation apparatus according to claim 1 , wherein the header forming part is formed to communicate with the passage of filtered water formed in the membrane cartridge, and is composed to communicate mutually with the header forming part formed in the other membrane cartridge disposed in parallel.

3. The membrane cartridge in the immersion type membrane separation apparatus according to claim 1 , wherein the header forming part is formed in a ring shape to project in the disposing direction of the membrane cartridge, and a header coupling convex part is formed at one side, and a header coupling concave part is formed at other side, so that they can be coupled together mutually.

4. The membrane cartridge in the immersion type membrane separation apparatus according to claim 1 , wherein the guide hole of the membrane cartridge disposed adjacently by varying the direction mutually is externally fitted to the header forming part of the adjacent other membrane cartridge, so that they can be coupled together mutually.
