Ozone destruction is the main goal of an ozone destructor. Although the application of ozone is one of the most environmentally friendly ways of disinfection and oxidation, it is crucial to destruct any excess or residual ozone in a safe way.
At this moment the US OSHA requires that the indoor "threshold limit value" (TLV) of an eight hour exposure be limited to 0,05 part per million (0,05 ppm). Worldwide tightening of ozone emissions will intensify within the next several years, forcing many operations to install control systems to destroy off-gas ozone to meet the new standards.
Ozone can be thermally destroyed (reduced to oxygen) but also catalytically. The catalytic destruction of ozone is the most used process, because it is easy to install on new and existing ozone generating systems and it is cost effective. Caution must be taken with the design and dimensions of the destructor to make sure the pressure drop and temperature rise is not too much.
