Choosing the Right Ozone Decomposition Catalyst for Reliable Emission Control
When ozone is used as a powerful oxidant for disinfection, oxidation, or surface treatment, managing residual ozone is no longer optional—it is a regulatory, operational, and safety necessity. From municipal water treatment plants to industrial process exhausts and laboratory systems, uncontrolled ozone emissions pose serious health risks and compliance challenges.
This is where DEAI CHEM’s Ozone Decomposition Catalyst solutions play a critical role. Designed for passive, ambient-temperature operation, our catalysts provide a proven and maintenance-friendly method to convert ozone into oxygen before release—without secondary pollutants or complex energy input.
Why Ozone Destruction Requires a Purpose-Built Catalyst
Ozone (O₃) is highly effective but inherently unstable and toxic at low exposure levels. Air emission standards in many regions impose strict limits on allowable ozone concentrations, particularly in enclosed or occupied environments.
However, ozone off-gas conditions are rarely uniform. Real-world systems must account for:
• Variable ozone concentrations
• High humidity and fluctuating temperatures
• Limited installation space
• Continuous or intermittent operation
A generic solution often fails under these conditions. Catalyst composition, geometry, and particle size directly determine efficiency, pressure drop, and service life.
DEAI CHEM Ozone Decomposition Catalyst: Engineered for Practical Performance
DEAI CHEM’s ozone decomposition catalysts are based on manganese oxide–copper oxide (MnO₂–CuO) active systems, a formulation widely recognized for its high ozone destruction efficiency and long-term stability.
Key Functional Advantages
✅Ambient-temperature operation – no external heating required
✅High catalytic activity for rapid ozone conversion
✅No harmful by-products – ozone is decomposed into oxygen only
✅Passive and maintenance-light design
✅Proven performance across industrial and municipal applications
These characteristics make the catalyst suitable for continuous operation in safety-critical environments.
Catalyst Forms and Mesh Sizes for System-Level Optimization
Ozone destruction performance is not solely determined by chemistry—it is equally dependent on physical configuration. DEAI CHEM offers multiple catalyst forms to integrate seamlessly into different system designs:
Available Catalyst Configurations
4 × 8 mesh
8 × 14 mesh
Optimized for packed beds and low pressure drop designs
Suitable for fixed-bed reactors and confined housings
Uniform flow distribution and mechanical strength
Designed for coating onto metal honeycomb, ceramic, or fibrous substrates
This flexibility allows engineers to balance contact time, pressure drop, durability, and footprint based on real operating constraints.
Typical Applications Across Industries
DEAI CHEM ozone decomposition catalysts are deployed globally in systems where reliability and compliance are non-negotiable:
• Municipal drinking water and wastewater treatment
Destruction of ozone off-gas from disinfection processes
• Industrial ozone generators
Corona discharge and non-thermal plasma systems
• Laboratory and medical facilities
Controlled exhaust treatment for occupational safety
• Office and electronic equipment
Residual ozone removal from copiers and printing systems
• Chemical processing exhaust
Protection of downstream equipment and ventilation systems
In all cases, the catalyst operates passively, converting ozone to oxygen before discharge.
Designing an Effective Ozone Destruction System
For optimal performance, ozone catalyst selection should consider:
• Ozone concentration and gas flow rate
• Humidity and temperature conditions
• Available reactor volume
• Target pressure drop
• Integration with existing exhaust or scrubber systems
DEAI CHEM supports customers with application-driven catalyst selection, ensuring the correct mesh size and geometry are matched to system requirements rather than forcing a one-size-fits-all solution.
A Practical, Long-Term Approach to Ozone Emission Control
Effective ozone destruction is not about short-term compliance—it is about long-term operational stability, safety, and cost control. By combining proven MnO₂–CuO chemistry with configurable catalyst forms, DEAI CHEM delivers ozone decomposition solutions that work reliably under real-world conditions.
As ozone applications continue to expand across water treatment, industry, and advanced oxidation processes, selecting the right catalyst partner becomes a strategic decision—not just a technical one.
