<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for manufacturing gas-dissolved water by using a gas-dissolving membrane module, wherein condensed water is discharged without varying dissolved-gas concentration. <P>SOLUTION: Raw water is allowed to pass to a water chamber 5, and gas is supplied from a gas supply source 10 to a gas chamber 6 to manufacture the gas-dissolved water. When operation is continued, water permeating a gas permeation membrane 4 is condensed, and the condensed water is gradually collected. When water quantity in the gas chamber 6 increases, the pressure in the gas chamber 6 gradually increases as the water quantity increases. When a pressure in the gas chamber 6 becomes larger than the cracking pressure of a check valve 14, the check valve 14 is opened and the water in the gas chamber 6 is discharged through a pipe 15. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
