<p>Provided are an operating method and operating system for a membrane separation device which make it possible to obtain permeated water having favorable water quality from a large-scale membrane separation device having a large-diameter membrane element with a diameter of 20cm or larger. A method for operating a membrane separation device in which a membrane element (2) having a diameter of 20cm or larger is positioned inside a cylindrical vessel (1), the method and system for operating the membrane separation device being characterized in that (a/n)/b equals 0.1-0.2, given that a (m3/h) is the amount of permeated water from the membrane separation device, b (m3/h) is the minimum brine solution amount from the membrane element (2), and n (n is 1 or higher) is the number of membrane elements.</p> |
