Abstract

This invention is directed to a sterilization method of contaminated areas with biological agents by making use of the acidic ozone water that very effectively kills spores of Bacillus atrophaeus, thereby demonstrating the capability of sterilizing a large surface-area in a very short time and reinstating the contaminated environment as free from toxic biological agents. The effective sterilization of the acidic ozone water is due to synergic benefits derived from the combination of ozone and acidity. The acidic ozone water can also effectively kill other ordinary microbes of viruses, bacteria, and fungi, hence being applicable to agriculture, seafood and livestock industries for the preservation of various products as well as being useful in hospitals or other germ infested areas for disinfections. Particularly, the acidity and ozone in the seawater sterilize microbes effectively, demonstrating a potential for the sterilization of a large amount of seawater in a short time. After the decontamination process, the acidic ozone water disintegrates into water and oxygen without any trace of harmful materials to the environment.

Claims

1. A process for the disinfections of microbes in a germ infested area, biological warfare agents on a contaminated surface by the introduction of an acidic ozone water, or a combination thereof to which said germ infested area, said contaminated surface, or said combination thereof is exposed, comprising:

converting a water selected from the group consisting of tap water, sea water, deionized water and a combination thereof to an acidic water by mixing the water with hydrochloric acid (HCl);

converting the acidic water to an acidic ozone water by dissolving ozone into said acidic water;

chilling or freezing the acidic ozone water to prepare a chilled or iced acidic ozone water;

applying said chilled or iced acidic ozone water to said germ infested area or said contaminated surface; and

sterilizing said microbes and said biological warfare agents by contact to said acidic ozone water.

2. The process according to claim 1, wherein said chilled or iced acidic ozone water is applied to said germ infested area selected from the group consisting of farmlands, livestock sheds, biological laboratories, hospitals, and a combination thereof.

3. The process according to claim 1, wherein said chilled or iced acidic ozone water is applied to said contaminated surface comprising large surfaces contaminated by said biological warfare agents.

4. The process according to claim 1, wherein said microbes are viruses, bacteria, fungi, or a combination thereof.

5. The process according to claim 1, wherein the pH value of said acidic ozone water is in the range of 2-6.

6. The process according to claim 1, wherein the ozone concentration of said acidic ozone water is in the range of 1-50 mg/L.

7. The process according to claim 1, wherein the water to be converted to the acidic water is tap water.

8. The process according to claim 1, wherein the water to be converted to the acidic water is sea water.

9. The process according to claim 1, wherein the water to be converted to the acidic water is deionized water.

10. The process of claim 1, wherein the process consists of said converting the water, said converting the acidic water, said chilling or freezing the acidic ozone water, said applying said chilled or iced acidic ozone water and said sterilizing said microbes and said biological warfare agents.

11. The process of claim 1, wherein the iced acidic ozone water is prepared and the iced acidic ozone water is applied.
