O3 is the chemical symbol for ozone, which consists of three oxygen atoms, and in fact exists all around us in the earth’s atmosphere: 0.005ppm of ozone is always present in air, working continuously to clean the air. In woodlands, there exists roughly 0.005-0.01ppm of ozone which preserves the environmental balance of plant matter. The Ozone layer that covers the globe also protects us against harmful ultraviolet rays.
Ozone decomposes naturally to O3 ? O2 + O at a rapid rate, and this decomposition is the stage at which its oxidizing and sterilizing power is effective.
Ozone bleaching techniques can be applied to other fields such as:
