In a typical biofiltration system, contaminated air is drawn through a bed of activated carbon at a controlled velocity to ensure adequate contact time. The air stream diffuses into the carbon pores, where pollutants are trapped. Clean air exits the bed, while the adsorbed compounds are held until they can be broken down by microbial activity. The rate of adsorption is influenced by the concentration of pollutants in the air: higher concentrations increase the driving force for adsorption, but they also lead to faster saturation of the carbon. System designers must balance these factors to achieve optimal performance, often using multiple carbon beds in series or parallel configurations to handle varying loads.

Factors Affecting Adsorption Performance

Several key variables influence how effectively carbon performs in a biofiltration system. Temperature plays a signitant role, as adsorption is an exothermic process that is favored at lower temperatures.
