Ozone generators work by converting oxygen molecules (O2) into ozone molecules (O3). This process is typically achieved through one of two methods:
Corona Discharge: This is the most common method. In this approach, air (or pure oxygen) is exposed between two electrodes, one of which carries a high
voltage. This high voltage creates a corona discharge (a kind of low-temperature electrical arc) between the electrodes. The corona has enough energy to
break down oxygen molecules (O2) into individual oxygen atoms. These individual oxygen atoms then combine with other oxygen molecules to form ozone (O3).
Ultraviolet (UV) Photolysis: In this method, ultraviolet (UV) light is used to break down oxygen molecules into individual oxygen atoms. This method mimics
the natural production of ozone in the upper atmosphere. When oxygen molecules absorb specific wavelengths of ultraviolet light, they split into individual
oxygen atoms. These oxygen atoms then combine with oxygen molecules to form ozone.
Regardless of the method used, the generated ozone can then be utilized in various applications, such as air and water purification, disinfection, and odor
removal. Ozone is a powerful oxidant and can effectively kill bacteria, viruses, and other microorganisms. However, it is also important to note that ozone can
be harmful to human health at high concentrations, so caution is necessary when using ozone generators.
From a scientific and biological standpoint, ozone works by damaging the cell walls of microorganisms. Its high oxidation potential disrupts the integrity of
bacteria, viruses, and fungi, leading to their inactivation. Ozone can also oxidize organic and inorganic substances found in water and air, aiding in the removal
of contaminants. However, due to its reactive nature, ozone decomposes back into oxygen relatively quickly, which means it doesn't leave harmful residues.
This reactivity also means that ozone must be generated on-site for effective use, as it cannot be stored and transported like other disinfectants.
