DEVICE FOR REMOVING DISSOLVED GAS AND SUPPLYING GAS

PURPOSE:To obtain a device for removing a dissolved gas and supplying a gas with the setting space and cost reduced and capable of being fabricated in a short time by providing the device with plural modules or sheets for removing the gas dissolved in a liq. and supplying a gas formed with the woven or knit fabric of a hollow-fiber membrane, a deaeration controller, a driving mechanism, a gas supply controller and a driving mechanism. CONSTITUTION:The device for removing dissolved gas and supplying gas has a function placed in a casing 1, allowing the raw water as city water to flow into the device from the part 1a of the casing, removing an org. halogen compound represented by all the trihalogenated methanes in the atom by a dissolved gas removing and gas supplying module 10 and discharging the resultant water into a bath from the part 1c of the casing and a function introducing the raw water in the bath into the device from the part 1b of the casing, supplying carbon dioxide into the raw water by a dissolved gas removing and gas supplying module 10' and discharging the carbon dioxide dissolved water into the bath from the part 1c. Since the control circuit can be used for discharging and charging a gas, the system is miniaturized, and the cost is lowered.
