<P>PROBLEM TO BE SOLVED: To provide a filtration membrane winding type filtration device capable of achieving fluid filtration treatment without leak or mixing in a filtration treatment flow channel after securing large filtration treatment capability without increase in structure size and achieving replacement maintenance of a filtration membrane by a simple winding operation. <P>SOLUTION: This filtration membrane winding type filtration device comprises a filtration treatment flow channel for a fluid crossing a filtration membrane 3 supported by a winding type filtration membrane support part 4 in a filtration chamber 2. The filtration chamber 2 comprises a supply part 2a for a filtration object liquid A and an extraction part 2b of a filtered liquid B in a separable manner. The supply part 2a and the extraction part 2b are provided with multi-hole receiving members 5, 6 receiving the respective surfaces of the filtration membrane 3, the receiving members 5, 6 facing each other. The facing surfaces are formed along a curved surface bent in a winding direction of the filtration membrane 3. The extraction part 2b is provided with a close-contact opening D in close contact at the entire circumference by a seal member 8 for the filtration membrane 3 to form the filtration treatment flow channel while supporting the multi-hole receiving member 6, wherein the close-contact opening is formed in a range of the filtration treatment flow channel of the supply part 2a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
