Abstract: A method of treating air containing odoriferous substances of both large and small molecular weights includes the step of establishing a flow of the air containing the odoriferous substances. The stream of flowing air is exposed to a bath in the form of a fine spray or mist of a concentrated solution of potassium permanganate at a first treatment zone to primarily oxidize the odoriferous substances having the smaller molecular weights and wash the air. The air is then passed through an adsorbing medium in the form of a bed of activated carbon at a second treatment zone to substantially adsorb and remove the remaining odoriferous substances having the larger molecular weights. Advantageously, the mist or droplets of the spray solution are removed from the air subsequent to movement from the first treatment zone and prior to movement into the second treatment zone. With the method, the air is substantially free of odoriferous substances upon removal from the second treatment zone.
