Ozone Destractor

Ozone Destructor

Although ozone is one of the most effective and environmental friendly disinfection and oxidation alternatives, it is crucial to decimate the excess or residual ozone to ensure safe working environment nearby the installation as it is highly toxic and can be very harmful to people and other living organisms since it is accused to be genotoxic. Occupational Safety and Health Administration (OSHA) sets a maximum threshold value for ozone concentration in air at 0.1 ppm for 8h of exposure. Ozone destruct units are designed to efficiently convert high levels of ozone into oxygen, decreasing it, in order to comply with the relevant legislation.
The catalytic destruction of ozone is the most promising process as it is an economically robust and easy to install on either new or existing ozone generating systems utilizing high ozone concentrations. A catalytic destructor, built with an amalgam of manganese dioxide and copper oxide (MnO2/CuO), converts ozone to oxygen, and controversy to activated carbon, neutralizes the risk of combustion since the temperature is not increased. The material functions through a continuous oxidation-reduction cycle. Although, MnO2 life time is indefinite since it transforms ozone to oxygen without being consumed, independent on the ozone concentration that goes through, the catalytic ability is reduced, due to impurities which are contained in the air stream. Thus, pre-filters are recommended to capture these compounds in prior to contact with the main catalyst.
