ABSTRACT:
A process for purifying polluted air includes passing the polluted air through a fluidized bed of micro-organism-containing particulate media. As the polluted air passes through the fluidized bed, organic pollutants therein are decomposed by the micro-organisms. Purified air containing a lower level of the organic pollutants than the polluted air that enters the fluidized bed, emerges from the fluidized bed.
