Advantages

HiPOx Advantages

  • Superior ozone utilization/High mass transfer
    • Lower Applied Ozone Dose
    • Less Power Consumption
    • Less Oxygen Usage
  • Superior Mixing
    • Maximize reaction efficiency
    • Faster reaction
    • Smaller footprint
  • Capability for Bromate Control
  • Pre-packaged, pre-assembled systems
    • Lower installation costs

AOP Comparison of HiPOx vs. UV/H2O2

Typical Factors

  • Hydrogen peroxide utilization is poor for UV/H2O2 since only 10-15% of hydrogen peroxide is utilized = Higher hydrogen peroxide costs and higher quenching costs
  • UV lamp replacement and sleeve cleaning increases maintenance costs and downtime relative to ozone systems
  • Power requirements for UV in AOP mode are 3 -6 times higher than UV in disinfection mode
HiPOx (O3/H2O2) UV/H2O2
• UVT – not a factor, means HiPOx can be used as either pre-treatment or post-treatment
• Typically lower hydrogen peroxide dose (2.5-5 mg/l for MF effluent)
• Hydrogen peroxide utilization of 75-100%
• Ozone generally recognized as superior oxidant to UV for many trace organics
• Ozone and OH very effective at virus removal (no coliform in membrane treated effluent)
• Bromate formation may be controlled with HiPOx or bromate removed by RO
• Very sensitive to UVT, determines power consumption
• Typically higher hydrogen peroxide dose (5-10 mg/l for MF Effluent)
• Hydrogen peroxide utilization of 10-15%, increases quenching costs or chlorine demand
• UV Dose in AOP mode is 3 – 6 times greater than UV Dose in disinfection mode
• No bromate formation
