ABSTRACT:
A method of treating air containing odoriferous substances includes the step of introducing ozone into the contaminated air at a first treatment zone and exposing the contaminated air to the ozone for a predetermined time period. The ozone is maintained in contact with the odoriferous substances for a sufficient time to oxidize a substantial portion of the latter. The mixture of ozone and air is then transferred to a second treatment zone where the ozone remaining in the mixture not utilized in the oxidation process is converted into stable oxygen molecules. In this manner, the treated air is substantially free of odoriferous substances as well as ozone upon the removal thereof from the second treatment zone.
