Description of the Related Art Conventionally, this kind of membrane separation apparatus is constituted by arranging a plurality of filtration membrane modules in parallel at appropriate intervals. In such a filtration membrane module, an organic filtration membrane such as an ultrafiltration membrane or a microfiltration membrane is adhered and fixed at the periphery on the front and back of a rectangular plate-shaped membrane support, and penetrated inside the filtration membrane. A permeate suction tube is provided. Then, the filter membrane module is immersed in the liquid to be treated in the tank, and a negative pressure is applied through the permeated liquid suction pipe, thereby filtering the liquid to be treated with the organic filtration membrane. At this time,
For example, a spacer is interposed between the organic filtration membrane and the membrane support to prevent adhesion between the filtration membrane and the membrane support, thereby forming a membrane permeate flow path.

FIG. 1A is a front view of a filtration membrane module, and FIG. 1B is a cross-sectional view taken along line AA ′ of FIG. 1A. The filtration membrane module 1 is composed of two rectangular flat plate-like membrane supports 2 bonded to each other, and filtration membranes 3 are arranged so as to cover both surfaces thereof. Each membrane support 2 has a frame shape with a rectangular space 4 provided in the center, and this frame portion 5 is integrally provided with a half of a cylindrical nozzle 6 communicating with the center space 4. And extends outside the membrane support 2 in a direction parallel to the plane of the membrane support 2.
In the space 4 of the membrane support 2, a cross 7 that is crossed vertically and horizontally is arranged, and one surface of the cross 7 is on the same plane as one surface of the membrane support 2. A filtration membrane 3 is provided. The other surface of the bar 7 is inside the other surface of the membrane support 2, and forms a concave space with the frame portion 5 and the bar 7. Then, the two membrane supports 2 are bonded together such that the filtration membrane 3 is on the outside, and the spacer 8 is inserted into the space formed between the concave spaces of both membrane supports 2, and A module 1 is formed.
