What Are the Main Sources of Ozone in Industrial Manufacturing?
Ozone (O₃) is a highly oxidative gas that is widely encountered in industrial manufacturing. It can be intentionally generated for industrial applications or produced as a by-product during certain manufacturing processes. With increasingly strict environmental, safety, and occupational health requirements, the sources and control of industrial ozone have become increasingly important.
In industrial applications, ozone sources can generally be divided into two categories: intentionally generated ozone and by-product ozone generated during industrial processes.
The most common source of industrial ozone is ozone generators. Industrial ozone is mainly produced through high-voltage corona discharge technology. When oxygen or air passes through a high-voltage electric field, some oxygen molecules (O₂) are split into oxygen atoms, which then combine to form ozone.
The reaction process is as follows:
3O2→2O3
This method is widely used in:
- Water treatment
- Air purification
- Food sterilization
- Medical disinfection
- Semiconductor cleaning
- Printing and packaging industries
Among these systems, oxygen-fed ozone generators can produce higher ozone concentrations, while air-fed systems are generally more cost-effective.
In addition, ozone can also be generated as a by-product during the operation of many industrial devices. Especially under high-voltage discharge, ultraviolet radiation, or high-energy electron exposure, oxygen in the air can naturally form ozone. Common equipment that generates ozone includes:
- Corona treaters
- UV curing systems
- Laser equipment
- Electrostatic precipitators
- X-ray equipment
- High-voltage electrical systems
In the film, coating, and printing industries, corona treatment systems are one of the major sources of ozone emissions. While improving surface tension and material adhesion, these systems also generate significant amounts of ozone. Without proper control, ozone can corrode equipment and negatively affect worker health.
Furthermore, ozone is intentionally used in wastewater treatment and municipal water disinfection systems for oxidation and sterilization purposes. If the exhaust gas from these systems is not properly treated, ozone emissions can also become an environmental issue.
Due to its strong oxidative properties, high concentrations of ozone can be harmful to the human respiratory system and may damage rubber materials and electronic components. Therefore, industrial facilities typically install ozone decomposition catalysts or ozone destruction systems to rapidly convert ozone back into oxygen, ensuring compliance with environmental and safety standards.
As industrial environmental regulations continue to tighten, ozone control and ozone exhaust treatment have become increasingly important across many manufacturing industries.
