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. An apparatus for sterilizing microbes on a contaminated area and for sterilizing microbes in water, said apparatus comprising:

a device for forming an ozone gas;

an acid material supply unit containing acid material comprised of HCl;

a mixing device for dissolving the acid material supplied from the acid material supply unit into water to produce an acidic water;

a mixing device for dissolving said ozone gas into said acidic water to form an acidic ozone water;

a device to spray said acidic ozone water on a contaminated area for sterilization of microbes; and

a device for freezing said acidic ozone water to produce acidic ozone ice.

2. The apparatus according to claim 1, wherein said microbes are viruses, bacteria and fungi comprised of biological warfare agents, that cause the deterioration of products from agricultural, seafood and livestock industries, that cause diseases to farm crops and livestock, and that infest hospitals, products from drug manufacturing industries and areas prone to germs.

3. The apparatus according to claim 1, wherein said contaminate area is the area contaminated by said microbes.

4. The apparatus according to claim 1, wherein the acid material supply unit contains the acidic material consisting essentially of HCl.
