## Abstract

A filtering membrane module and a filtering apparatus having the same, which is capable of remarkably reducing a vibration of filtering membrane module during an aeration process for a maintenance cleaning of filtering membrane, and preventing a crack from occurring in the filtering membrane module by the vibration, wherein the filtering membrane module comprises a filtering membrane; a header, to which the filtering membrane is potted, including a first lateral side and a second lateral side opposite to the first lateral side; a first coupling unit provided at the first lateral side; and a second coupling unit provided at the second lateral side.

## Claims

### Claim 1

A filtering apparatus comprising:
a frame structure; and
a filtering membrane module installed in the frame structure, the filtering membrane structure including:
a filtering membrane;
a header with the filtering membrane potted thereto, the header including a first end part; and
a coupling ring provided at one end part of the header; and
wherein the frame structure includes a coupling member detachably combinable with the coupling ring so that the filtering member module cannot be separated from the frame structure when the filtering apparatus performs filtration.

### Claim 2 (depends on 1)

The filtering apparatus according to claim 1, wherein the coupling member includes a pair of elastic wings.

### Claim 3 (depends on 2)

The filtering apparatus according to claim 2, wherein each of the elastic wings includes a protrusion so as to prevent the coupling ring from being separated from the coupling member.

### Claim 4 (depends on 3)

The filtering apparatus according to claim 3, wherein the pair of elastic wings are bent to be closer to or farther apart from each other when the protrusions are passing through the coupling ring and are restored to their original positions right after the protrusions pass through the coupling ring.
