Abstract
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, a flow rate sensor, and a pressure sensorare provided in at least two membrane elementsprovided in a membrane filtering device. A managing deviceobtains 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 deviceand 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 devicemore definitely, and to carried out a suitable maintenance in accordance with the cause, so that the membrane filtering devicecan be managed with a higher precision.
