About Ozone

Ozone reacts with various organic and inorganic molecules and atoms due to its high reactivity and oxidizes them. As a result of these reactions, sterilization is achieved by neutralizing bacterial and microorganisms in the air. After completing the reaction period, the ozone molecules begin to convert to oxygen. Thanks to this feature, ozone does not leave waste contrary to other disinfectant substances and does not risk the formation of by-products.

What is Ozone?

Ozone gas (O3) is a colorless gas with molecules consisting of 3 oxygen atoms and is located in the upper layers of the atmosphere.

The allotropy of oxygen is also referred to as trioxygen. Under normal conditions, the amount of O3 in the lower parts of the atmosphere is about 0.4 ppm. However, the amount of ozone is increased in places where there is smoke. Ozone levels exceeding 0.12 are considered harmful to health. Ozone is the main cause of the blue color of sky. The ozone gas, which turns into a dark blue color, protects the Earth against harmful ultraviolet radiation from the Sun. UV rays in the upper layers of the atmosphere and ozone generated by the breakdown of the electric current generated by the lightning flashes in the lower layers play a very important role in cleaning the air. In developed countries, ozone is widely used in food textile logistics as a disinfectant in the health sector.

Ozone, the raw material of oxygen, is the only gas that cannot be stored and has no storage possibilities. The reason for not to be able to store the ozone gas is its conversion to oxygen in time proportional to the temperature of the environment. It is effective in the treatment of deep surgical wounds and is also used for therapeutic purposes in the health sector.

Ozone Generation

In the corona discharge method, while passing an electric current through the oxygen molecule O2 is fragmented, it is converted into reactive free oxygen atoms. When faced with free oxygen atoms of molecular oxygen is extremely unstable ozone molecules (O3) occurs. Ozone rapidly with molecular oxygen (O2) and free oxygen atoms (O), it is transformed into. Then re-other free oxygen atoms can combine with the free oxygen atoms can be converted to molecular oxygen. These reagents can react with other molecules in the environment. Therefore, ozone is a highly reactive component.

Ozone, elemental fluorine, chlorine trifluoride, atomic oxygen and hydroxyl radicals, which is the highest thermodynamic oxidation potential 5. the component is stated to be.

In the corona discharge method, one high current low current electrodes, two electrodes are used. Sufficient kinetic energy in the case of the electrodes of the oxygen molecule parses, each oxygen Atom and an ozone molecule consists of. In the case of air passing from the generator, 1-3% ozone produced from pure oxygen is used, this value is 6%. To break down ozone into oxygen atoms spontaneously, it is not possible to be stored.

Pure ozone is soluble in water and other gasses, such as, as temperature increases, solubility decreases. Ozone is a molecule with high energy which, at room temperature the half-time of 20 mins and at the end of this period it is stated to break down into oxygen without leaving a residue.

Ozone is used in applications equipment; generators, in contact with the product gas tanks, gas purification systems, ozone destruction units, filters and exhaust systems.
