Abstract

Provided is a membrane separation device that enables reduction of the membrane surface aeration flow amount to achieve reduction of operation cost. This membrane separation device includes: a separation membrane 2 which 5 filters treatment target water in the membrane separation tank 1; a membrane surface aeration device 5 which performs membrane surface aeration by a diffuser pipe 7 provided below the separation membrane; an organic substance concentration measurement means 19 which measures the organic substance 10 concentration in the treatment target water; a pressure measurement unit 17 which measures a transmembrane pressure of the separation membrane; transmembrane pressure increase speed comparing means 15 which compares a transmembrane pressure increase speed selected on the basis of the value of 15 the organic substance concentration measured by the organic substance concentration measurement means, with a transmembrane pressure increase speed calculated from the transmembrane pressure measured by the pressure measurement unit; and a control unit 16 which controls the membrane 20 surface aeration flow amount of the membrane surface aeration device 5, wherein the control unit 16 changes the membrane surface aeration flow amount on the basis of the difference between the transmembrane pressure increase speeds, obtained by the transmembrane pressure increase speed comparing means 25 82 15.
