The author reports the development of the new chemical water treatment technology using the aqueous of stabilization hypochlorous acid. This stabilization solution is prepared by the low environmental loading manufacturing equipment for very precise fluid control using diffusion phenomena. It is prepared from dilute hydrochloric acid and aqueous solution of sodium hypochlorite without the electrolysis. The work environment of the preparation process is very good, since the preparative procedure without using or generation of the chlorine. The prepared aqueous solution is high precise continuously prepared with optionally designated for the available chlorine concentration; 10 ppm < [available Cl] < 200 ppm, and the hydrogen ion exponent (the pH value; 5.0 < pH < 6.8). In addition, the aqueous solution is very long life, and it is possible to storage and/or prevails. This functional water is a solution presenting slightly acidic or neutrality without having the corrosiveness, since the hydrochloric acid is not contained in forming solution. Since it has the powerful oxidizability, this solution manifests very powerful pasteurization effect and deodorizing effect. This aqueous solution is used in order to deal with water supply, intermediate process water, and wastewater. It is widely applied in medicine, food processing, agriculture, livestock industry, fisheries field and so on. In addition, the author also reports applications of this technology for prevention of epidemics countermeasure.
