As its use in the United States grows, there is a need for design and operating information, and functional and economic evaluations of different systems. A review of the published biofiltration literature and an evaluation of biofiltration's capabilities and limitations is needed by engineers and potential users of this innovative technology. Results Over 220 publications were reviewed. The literature indicates that biofiltration is a competitive air pollution control technology that has been used in numerous industries to control VOCs and odors. Its reliance on microorganisms requires an appreciation of ecological principles and an understanding of microbial growth, and nutritional and environmental requirements.
Microbial characterization is limited.
Limited economic information suggests that biofiltration is cost effective. Few studies addressed potential occupational and public health aspects of biofiltration. 1997 Regents of the University of Minnesota. All Rights Reserved.
