Title: RESISTIVITY ADJUSTMENT DEVICE AND RESISTIVITY ADJUSTMENT METHOD
Abstract:
A resistivity adjustment device is provided with: a hollow fiber membrane module 2; a through-module pipe 5 that runs through the hollow fiber membrane module 2; a bypass pipe 6 for bypassing the hollow fiber membrane module 2; a liquid discharge pipe 7 for connecting the through-module pipe 5 and the bypass pipe 6 via a merge part 14 for merging the through-module pipe 5 and the bypass pipe 6 on the downstream side of the hollow fiber membrane module 2; a first flow detection unit 8 for detecting a first flow of liquid L that flows through either a liquid supply pipe 4 or the liquid discharge pipe 7; a control valve 9 for opening and closing the through-module pipe 5; and a control unit 10 for setting the degree of opening of the control valve 9 according to the first flow detected by the first flow detection unit 8.
