PROBLEM TO BE SOLVED: To prevent scattering of sterilized water to other facilities and prevent occurrence of abnormality such as lack of surfactant by spreading cream-like bubbles formed in a manner that air is blown before a spreading pipe of mixed solution and fine bubbles of specific times the volume of solution are mixed to control fluidity. SOLUTION: Hypochlorous acid of a volume necessary for sterilizing a thin to be spread and a surfactant for stabilizing bubbles are mixed to water. Air is blown into a mixed solution therefrom before a spreading pipe of the mixed solution to form fine bubbles in the solution. At this time, air, by volume, about 0.1 to 20 times the solution is added to mix to form the cream-like bubbles. Thereby, the apparent volume is increased, and a target surface is wet in sterilized water to prevent scattering to other facilities. For example, even on a gradient surface to be sterilized, the cream-like bubbles using the surfactant keep attaching to the target surface and improve sterilizing efficiency. |
