MEMBRANE FILTRATION EQUIPMENT MANAGEMENT SYSTEM AND MEMBRANE FILTRATION EQUIPMENT FOR USE THEREIN, AND MEMBRANE FILTRATION EQUIPMENT MANAGEMENT METHOD

摘要

Provided are a membrane filtering device managing system by which the membrane filtering device can be managed with a better precision and a membrane filtering device for use therein, as well as 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 sensors, 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 sensors. Accordingly, it is possible to specify the cause of changes occurring in the membrane filtering device (50) more definitely, and to carry out a suitable maintenance in accordance with the cause, so that the membrane filtering device (50) can be managed with a higher precision.
