Biofiltration is a biological air pollution control technology for vol
atile organic compounds (VOCs). This paper summarizes the fundamentals
, design and operation, and application of the process. Biofiltration
has been demonstrated to be an effective technology for VOCs from many
industries. Large and full-scale systems are in use in Europe and the
United States. With proper design and operation, VOC removal efficien
cies of 95-99% have been achieved. Important parameters for design and
performance are empty-bed contact time, gas surface loading, mass loa
ding, elimination capacity, and removal efficiency. Key design and ope
ration factors include chemical and media properties, moisture, pH, te
mperature, nutrient availability, gas pretreatment, and variations in
loading.
