Document Type and Number:
WIPO Patent Application WO/2016/167134
Kind Code:
A1
Abstract:
The present invention comprises: a hollow fiber membrane module that is divided, by a hollow fiber membrane, into a liquid phase-side region where a liquid for which the specific resistance value is adjusted is supplied and a gas phase-side region where an adjustment gas for adjusting the specific resistance value is supplied, the adjustment gas being dissolved in the liquid; a liquid supply pipe that is in communication with the liquid phase-side region and supplies the liquid to the liquid phase-side region; a liquid discharge pipe that is in communication with the liquid phase-side region and discharges the liquid from the liquid phase-side region; a gas supply pipe that is in communication with the gas phase-side region and supplies the adjustment gas to the gas phase-side region; a gas discharge pipe that is in communication with the gas phase-side region and discharges the adjustment gas from the gas phase-side region; a bypass pipe in communication with the liquid supply pipe and the liquid discharge pipe so as to bypass the hollow fiber membrane module; and a first opening/closing valve that is connected to the gas discharge pipe and opens or closes a first flow channel in the gas discharge pipe, wherein the first opening/closing valve discharges water collected in the gas phase-side region by opening the first flow channel.
