Research output : Chapter in Book/Report/Conference proceeding › Conference contribution

This paper summarizes a literature review on biofiltration and its capabilities for removing volatile organic compounds and inorganic pollutants from air. Biofiltration is an air pollution control technology that uses microorganisms to transform oxidizable vapors and gases into mostly innocuous end products. The reliance on microorganisms requires an appreciation of ecological principles and an understanding of microbial growth. Most biofilters treat air before it is exhausted to the atmosphere. Many of these systems have removal efficiencies greater than 90%. Biofiltration is cost competitive for removing biodegradable compounds at low concentrations. Costs increase as compound concentrations increase and treatability decreases. Potential occupational and public health aspects of biofiltration warrant further investigation. Biofiltration has been used as an air pollution control technology in numerous industries, including chemical, plastics, manufacturing, paper, food, wastewater treatment, and agricultural. Additional research is needed before considering its use for general air cleaning and removal of nonspecific contaminants.

Traditional air polllution control technologies for pollutant gases, such as adsorption, absorption and combustion, were developed to treat high concentration waste gas streams associated with process emissions from stationary point sources. Although these technologies rely on established physico-chemical principles to achieve effective control of gaseous pollutants, in many cases the control technique yields products which require further treatment before disposal or recycling of treatment materials. In the case of treatment of dilute waste gas streams, however, these traditional methods are relatively less effective, more expensive and wasteful in terms of energy consumption; and identification of alternative control measures is warranted. A suitable alternate air pollution control technology is biofiltration, which utilizes naturally occurring microorganisms supported on a stationary bed (filter) to continuously treat contaminants in a flowing waste gas stream. This application of aerobic biodegradation has received considerable attention and use in Europe, particularly in Germany and Holland during the last 15 years. 1–21 In the United States, however, relatively little attention 22–29 has been paid to this emerging, innovative and versatile ‘low’ technology approach to solving current environmental problems in air quality.

Waste gases biofiltration is an emerging technology, and has played important roles in air pollution control. In this paper, the structure of biofilter and biotrickling filter and their mechanisms in air pollution removal were introduced, with focus on the research advances in the isolation and identification of microbes in the filters, correlations between microbial abundance, activity and community diversity, influences of operation conditions on microbial community, spatiotemporal change patterns of microbial community structure during operation, development of biofilm, and biodegrading dynamic models. The research perspectives in microbial ecology during biofiltration of waste gases were discussed.
