Biological Odor Control

Biological oxidation is a process by which the micro-organisms consume dissolved oxygen and organic/inorganic substances in foul air streams, using the energy released to convert carbon into carbon dioxide and cellular materials. Biological systems achieve odor removal by a two - step process; 1) Mass Transfer Absorption via contact of the air stream with biofilm on the packing material in the vessel, followed by 2) Biological Oxidation of the odor compounds by the biomass.
