Description:
An advanced biofiltration system has been developed for the removal of trace organic contaminants in air. This bioscrubber uses activated carbon as a support for biogrowth. An advanced engineering design was incorporated into the bioscrubber to allow biomass removal and nutrient supplement if necessary. In a bench-scale study, >95% removal efficiency has been consistently demonstrated in an air stream containing 5 to 40 ppm of toluene for >11 mo. It shows a much higher degradation efficiency than the existing practice of using compost and other naturally occurring media under the same operating conditions. This bioscrubber also provides several operational advantages over conventional activated carbon adsorbers for soil, water, and air decontamination processes.
