Abstract:
To provide a filtration system which can reduce effort required to maintain and inspect a filtration membrane unit.SOLUTION: A filtration system comprises a plurality of filtration membrane units 21, and comprises a water collection pipe 90 which includes a main pipe part 91, and a plurality of individual water collection passages (located in a water collection part 92) which are arranged in an axial direction of the main pipe part 91 and communicate with the main pipe part 91. The filtration system collects filtrate filtered at a filtration membrane 22 in each of the plurality of filtration membrane units 21 into the main pipe part 91 of the water collection pipe 90 via an exhaust passage and the individual water collection passages of the water collection pipe 90. The filtration system comprises a lock member 98 which locks axial movement of the exhaust passage in each of the plurality of filtration membrane units 21. Each of the filtration membrane units 21 comprises an O-ring comprising an elastic material on an outer peripheral surface of an exhaust pipe forming the exhaust passage. In the state where the exhaust pipe is inserted in the individual water collection passage, axial movement of the exhaust pipe is locked by the lock member 98.SELECTED DRAWING: Figure 5
