A critical solution for safe exhaust gas treatment
Ozone (O₃) plays an important role in oxidation, disinfection, and water treatment processes. However, excessive ozone must not be released directly into the atmosphere. It is a strong oxidant and a regulated greenhouse gas, capable of irritating the respiratory tract and even causing long-term damage to the lungs at high exposure levels.
Therefore, safe decomposition of ozone before emission is not just a best practice—it is a regulatory and safety necessity.
DEAI CHEM’s Ozone Decomposition Catalyst is specifically engineered to convert ozone into oxygen reliably and continuously without external heating and without generating secondary pollutants. It serves as a passive safety layer for ozone treatment systems across industrial, environmental, and laboratory applications.
1. Working Mechanism
The catalyst facilitates a surface-based redox reaction under ambient conditions. As ozone molecules contact the catalyst, they are decomposed into harmless oxygen through a two-step reaction pathway:
• O₃ converts to O₂ and atomic oxygen
• The catalyst regenerates its active surface without degradation
• External energy is not required during operation
This passive reaction enables continuous treatment of ozone-containing exhaust streams with low maintenance requirements.
2. Major Application Fields
Ozone Decomposition Catalyst is commonly used wherever ozone is generated as a by-product or exhaust component. Typical installation scenarios include:
• Exhaust gas from ozone-based water disinfection systems
• Laboratory exhaust, ozone generators, and test chambers
• Corona discharge and dielectric barrier discharge equipment
• Non-thermal plasma reactors requiring end-of-line cleanup
• HVAC systems and dedicated exhaust purification units
In these environments, safe ozone removal is essential for compliance with emission standards and workplace safety regulations.
3. Product Forms & Integration
The catalyst is available in multiple physical formats to suit system design requirements:
Granular and pellet forms are commonly used in:
• Packed bed reactors
• Filter cartridges
• Gas scrubber canisters
They offer stable performance, low pressure drop, and long service life with minimal maintenance.
Powder form is designed for coating applications, particularly for OEM system integration. It can be applied onto various carriers, including:
• Metallic honeycomb substrates – recommended for high-durability and flame-rated systems where low pressure drop is critical
• Cellulose foams – offer high surface area and cost-efficiency for large-volume air treatment
• Non-woven fabric layers – suitable for lightweight HVAC and air filtration formats
This coating-based customization allows engineers to design compact and efficient ozone removal modules tailored to new technologies and emerging industries.
4. Industry Adoption
Municipal water treatment facilities are widely adopting ozone decomposition catalysts to purify ozone-laden off-gas before venting. The catalyst operates with zero external energy input, which significantly reduces maintenance and operational costs.
Additionally, the growing adoption of non-thermal plasma and advanced oxidation processes has resulted in increased demand for ozone treatment solutions. As these technologies evolve, catalyst-based ozone removal is becoming a standard requirement in system design.
5. Engineering Considerations
When implementing an ozone decomposition system, the following parameters must be evaluated:
• Concentration and airflow profile of ozone
• Reactor configuration and available space
• Acceptable pressure drop across the filter bed
• Humidity levels and material compatibility
• Target service life and maintenance schedule
DEAI CHEM provides technical support for system configuration, including particle size selection, substrate coating development, and performance verification for both new installations and retrofit applications.
Conclusion
Ozone cannot remain in exhaust gas streams unchecked. With increasing regulatory oversight and the rise of advanced oxidation technologies, ozone decomposition is not optional—it is essential.
DEAI CHEM’s Ozone Decomposition Catalyst offers a secure, passive, and proven method to eliminate ozone without producing harmful by-products.
