Ozone Static Mixer

An Ozone Static Mixer is a precision-engineered, stationary mixing element installed in ozone injection lines or contact chambers to promote thorough mixing and dispersion of ozone gas into water without mechanical energy or moving parts. In ozonation systems — whether for drinking water disinfection, wastewater oxidation, cooling tower sanitation, or food & beverage wash water — static mixers improve the mass transfer efficiency of ozone by generating controlled turbulence and increasing the gas–liquid interfacial area. This enhances the dissolution of ozone into water, supporting deeper oxidation, better contaminant removal, and more effective sanitation outcomes.

Eltech’s ozone static mixers are designed to integrate seamlessly with existing ozone injection systems, venturi injectors, contact tanks, and downstream processes, offering a robust solution for efficient ozonation in industrial, commercial, and municipal water applications.

Core Technology & Data

How Ozone Static Mixers Work

Static mixers are stationary flow devices inserted inline with the process piping. Unlike dynamic mixers, they do not require external power or moving parts. Instead, they consist of a series of specially shaped internal elements that divide and recombine the fluid streams as water and ozone gas pass through, creating:

• • Turbulent flow patterns
• • Increased gas–liquid contact surface area
• • Uniform mixing of ozone and water phases

When ozone gas is introduced upstream (e.g., through a venturi injector or gas injector), the static mixer’s internal geometry ensures that fine ozone bubbles are dispersed throughout the water stream, maximizing mass transfer and dissolution before the mixture reaches the contact or reaction zone.

Design & Material Considerations

Static mixers for ozone applications are typically made from materials with high resistance to ozone oxidation, such as:

• • PVDF (Polyvinylidene fluoride)
• • PTFE or Teflon-lined components
• • Ozone-resistant polymers
• • Stainless steel (where appropriate)

These materials withstand long-term exposure to ozone gas and ozonated water without degradation, ensuring reliable performance and longevity.

Static mixer designs vary by application, flow rate, and required turbulence intensity — with configurations optimized to match pipe diameters, ozone feed rates, and dissolved ozone targets.

Performance Data & Sizing

Static mixer performance depends on:

• • Flow velocity: Higher velocity promotes better mixing.
• • Mixer length and element design: Longer mixers with more internal elements generally yield increased turbulence and improved mixing quality.
• • Ozone feed rate and gas volume: Coordinating ozone dosage with mixer design ensures efficient ozone dispersion.

Proper mixer sizing ensures an adequate mixing length and residence time to optimize ozone dissolution before contact chambers or downstream oxidation processes.

Benefits & Performance Highlights

1. 1. Improved Ozone Dissolution & Mass Transfer
   Static mixers increase the efficiency of ozone dissolution into water by creating controlled turbulence and fine bubble dispersion — boosting gas–liquid contact without external energy input.
2. 2. No Moving Parts for Low Maintenance
   Because they are passive, mechanical-free devices, static mixers are highly reliable, require minimal upkeep, and reduce operating downtime compared to powered mixers.
3. 3. Enhanced Oxidation Performance
   By ensuring ozone is uniformly and efficiently distributed throughout the water stream, static mixers support deeper oxidation of contaminants, stronger disinfection, and better overall process performance.
4. 4. Energy-Efficient & Cost-Effective
   Static mixers use the existing flow energy of the system, eliminating the need for additional pumps or agitators — resulting in lower energy usage and reduced lifecycle costs.
5. 5. Versatile Integration
   

   Static mixers are compatible with:

   • • Venturi injectors and ozone feed lines
   • • Ozone contact tanks and chambers
   • • Inline water treatment loops
   • • Ozone measurement points for control feedback

   This flexibility makes them suitable for municipal, industrial, aquaculture, and process water ozonation systems.

6. 6. Durable Materials for Ozone Environments
   

   Constructed from ozone-resistant polymers or coated metals, Eltech static mixers withstand long-term exposure to ozone and water without corrosion or degradation.

7. 7. Uniform Mixing Reduces Ozone Waste
   By dispersing ozone more evenly and thoroughly, static mixers minimize off-gas and unused ozone, improving ozone utilization and lowering total oxidant costs.
8. 8. Consistent Contact Before Reaction Zones
   Static mixers prepare a well-mixed ozone–water phase before it enters contact chambers or reaction tanks, supporting measurable CT values and predictable treatment outcomes.

⚠️Installation & Safety Note
Static mixers must be properly sized and installed inline with system piping based on design flow rates and ozone feed volumes. Adequate provisions for degassing or ozone off-gas destruction should be included downstream to prevent ozone release into workspaces and comply with safety standards.
