How Does an Ozone Generator Work?

Ozone (O3) is a molecule composed of three oxygen atoms. It is a gas with special chemical properties and a strong odor. In the atmosphere, ozone exists in the form of the ozone layer, located in the Earth’s stratosphere, which is able to absorb and shield ultraviolet radiation from the sun, protecting life on Earth from harmful ultraviolet radiation. An ozone generator, also referred to as an ozone machine, functions as a tool that transforms oxygen sourced from different outlets like the ambient air, dry air, or concentrated oxygen, into ozone. By adding energy into oxygen molecules (O2), ozone generators generate ozone (O3), prompting the oxygen atoms to disassociate and temporarily combine with other oxygen molecules. This ozone is then used for water disinfection and air purification.

Ozone is a strong oxidizing agent with strong oxidation capacity and is therefore widely used as a strong oxidizing agent in many applications to eliminate organic pollutants, bacteria and viruses. When it comes to air purification, ozone is used as a powerful oxidizer that effectively removes odors, harmful gases and bacteria from the air. Through ozone oxidation, it can decompose and degrade organic and inorganic pollutants, improve indoor and outdoor air quality, and provide people with a fresher and healthier breathing environment. In water treatment field, ozone also plays an important role in purifying water, removing organic matter, killing bacteria and viruses. Its high oxidizing property can quickly break down organic compounds in water, improving the smell and taste of water and ensuring a clean and safe drinking water supply.

The use of ozone provides many benefits in a wide range of applications, but at the same time, safety issues need to be carefully addressed. Ozone is a powerful oxidizing agent and it is potentially dangerous. When using ozone generators or other ozone generating equipment, strict operating guidelines must be followed to ensure the safety of the operator and the environment. High concentrations of ozone may cause irritation to the human respiratory system, especially for sensitive people. Therefore, when using ozone for air purification, water treatment or medical applications, appropriate control measures must be taken to ensure that ozone concentrations do not exceed safety limits Appropriate ventilation and protective measures must be taken to minimize potential risks.
