Apparatus for controlling odors

摘要: A method of treating air containing odoriferous substances both large and small molecular weights includes the step establishing a flow substances. The stream flowing is exposed to bath in form fine spray or mist concentrated solution potassium permanganate at first treatment zone primarily oxidize having smaller wash air. then passed through an adsorbing medium bed activated carbon second substantially adsorb remove remaining larger weights. Advantageously, droplets are removed from subsequent movement prior into zone. With method, free upon removal advantageously recycled purified so that same may be efficiently utilized more than once provide for apparatus carrying out described.
