Abstract

An odor removal system includes an odorous gas inlet, a treated gas outlet and a gas treatment flow path from the odorous gas inlet to the treated gas outlet. A mixer is coupled in series with the gas treatment flow path and has an ozone inlet coupled to an ozone outlet of an ozone generator. A non-thermal plasma reactor is also coupled in series with the gas treatment flow path.
