Provided are a membrane filtering device managing system by which the membrane filtering device can be managed with a better precision and membrane filtering device for use therein, as well as to a membrane filtering device managing method. At least two sensors of an electric conductivity sensor 11, a flow rate sensor 13, and a pressure sensor 15 are provided in at least two membrane elements 10 provided in a membrane filtering device 50. A managing device 200 obtains data from the at least two sensor, and compares the data with comparison data that represents a correlative relationship between a position along the axial line direction in the membrane filtering device 50 and a standard value obtained from the at least two sensor. Accordingly, it is possible to specify the cause of change occurring in the membrane filtering device 50 more definitely, and to carried out a suitable maintenance in accordance with the cause, so that the membrane filtering device 50 can be managed with a higher precision.
A membrane filtering device managing system comprising:
A membrane filtering device managing system comprising:
A membrane filtering device managing method for managing a membrane filtering device that is formed by disposing and arranging a plurality of membrane elements along an axial line direction within a tubular pressure-resistant vessel and generates a permeated liquid by filtering a raw liquid with the membrane elements, comprising:
