METHOD FOR MANUFACTURING NANO-BUBBLE WATER CONTAINING SATURATED GAS

摘要

PURPOSE: A manufacturing method of nano-bubble water containing saturated gas is provided to generate the always stable saturated gas nano-bubble water successively through the long term by reducing the specific resistance of gas melt pure water before the nano-bubble generating process. CONSTITUTION: The manufacturing method of nano-bubble water containing saturated gas includes the steps of: producing the deaerated pure water by deaerating the pure water(a); producing gas dissoved pure water of saturated gas by pressurizing and dissolving the gas of dissolving purpose to the deaerated pure water(b); controlling the pressure of the gas of the dissolving purpose(c); producing the nano bubble water containing the saturated gas by reducing the pressure of gas dissolving pure water(d). The method includes more step of reducing the specific resistance of gas dissolving pure water before the process of nano-bubble generation. The reduction of the specific resistance of the gas dissolving pure water reduces the specific resistance by injecting at least acid or alkali and controls the reducing degree of the specific resistance.
