Applications for Catalytic Ozone Destruct Units

Vent-gases containing trace levels of unreacted ozone must be passed through a catalytic or thermal type vent ozone destruct unit before being released to the atmosphere. Catalytic ozone destruct units are meant to be used in all main applications of ozone.

This includes especially:

  • Drinking water treatment
  • Industrial oxidation processes
  • Process water disinfection
  • Advanced oxidation processes

The Ozonia cVOD units are also applicable for wastewater applications, when the ozonation step intervenes as a final treatment.


  • Very high ozone destruct efficiency
  • Low power consumption
  • Long service life
  • Virtually maintenance-free
  • Easy integration
  • Compact footprint
  • Oxygen or air-based feed gas
