Abstract

A first fixing member which fixes to a membrane module unit a tubular member with a protrusion formed at a tip end or near the tip end for connecting a membrane module of the membrane module unit and a water collecting header to form a filtrate flow path from the membrane module to the water collecting header, the first fixing member includes: a fixing member main body which includes an engaging surface formed at a position at which the fixing member main body engages with the protrusion formed in the tubular member; and a second fixing member which fixes the fixing member main body to the membrane module unit.

First claim

The invention claimed is:

1. A first fixing member which fixes a tubular member with a protrusion provided in a proximity of a distal end of the tubular member for connecting a membrane module of the membrane module unit and a water collecting header to form a filtrate flow path from the membrane module to the water collecting header, on a membrane module unit, the first fixing member comprising:
a fixing member main body which includes an engaging surface formed at a position at which the fixing member main body engages with the protrusion formed in the tubular member; and
a second fixing member which fixes the fixing member main body to the membrane module unit,
wherein the fixing member main body has a stepped shape with crank shape having two parallel plates connected by a vertical plate, formed by bending a plate.

2. The first fixing member according to claim 1 ,
wherein the fixing member main body has a plate shape.

3. The first fixing member according to claim 2 ,
wherein a plate thickness of the fixing member main body is not less than 1 mm and not more than 2 mm.

4. The first fixing member according to claim 1 ,
wherein the engaging surface includes an engaging portion configured by a surface which engages with the protrusion formed in the tubular member in one or more notch peripheral surfaces formed in the fixing member main body and/or in a region set on both sides of each notch.

5. The first fixing member according to claim 1 ,
wherein the protrusion is a flange formed over an entire outer periphery of the tubular member.

6. The first fixing member according to claim 5 ,
wherein the engaging surface includes a flange engaging portion which is set in one or more notch peripheral surfaces formed in the fixing member main body and/or on both sides of the notches and includes a flange engaging portion that engages the flange of the tubular member in a region within a substantially semicircular arc of the flange.

7. The first fixing member according to claim 5 , further comprising:
a sealing member which is arranged between the flange engaging portion and the flange.

8. The first fixing member according to claim 6 , further comprising:
a sealing member which is arranged between the flange engaging portion and the flange.
