<P>PROBLEM TO BE SOLVED: To provide a method for producing saturated gas-containing nano-bubble water and a device for producing the saturated gas-containing nano-bubble water, allowing continuous acquisition over a long period of the always stable gas saturated nano-bubble water. <P>SOLUTION: This method for producing the saturated gas-containing nano-bubble water includes: a deaeration process A of deaerating pure water to generate deaerated pure water; a gas dissolution process B of dissolving a pressurized gas in the deaerated pure water to generate saturated gas dissolution pure water wherein the gas is saturated; and a nano-bubble generation process D of reducing the pressure of the gas saturated dissolution pure water passing through the gas dissolution process B to generate the saturated gas-containing nano-bubble water. The pressure of the dissolved gas is controlled in the gas dissolution process B, and the resistivity of gas dissolution pure water is reduced before the nano-bubble generation process D. <P>COPYRIGHT: (C)2012,JPO&INPIT |
