Tackle airborne organic vapors with biofiltration
- ERM, Inc., Exton, PA (United States)
The control of volatile organic compound (VOC) emissions has become a substantive issues for industrial operators, as a result of the implementation of many titles of the US 1990 Clean Air Act Amendments, and similar regulations in Europe. VOCs can be captures for destruction or collected for reuse using a variety of physical, chemical and biological treatment schemes. For years, air-pollution-control specialists have relied on the traditional physical and chemical approaches. However, recent advances in biotreatment systems have broadened the appeal and the practicality of microbial treatment for vapor streams. In many cases, they present a less capital- and maintenance-intensive approach to destroying VOCs. The use of biofilters for contaminated air streams is analogous to the use of biological-treatment systems for wastewater, or in situ bioremediation of contaminated soil and hazardous sludge. The principles of using biofiltration, and key requirements for optimizing biofilter operation are discussed.
