“…Concentrations of individual pollutants are in general much lower than those of substances used in the laboratory studies (Table 1), especially those of the VOCs. For this reason and the fact that gas flow rate values are much more vari- [55], and Wolstenholme & Finger [57]). These seem to indicate that biofilters for H 2 S and odor treatment are also capable of removing a broad range of VOCs.…”

“…[1][2][3] However, the absence of a free liquid makes it sometimes difficult to control key environmental parameters such as pH and moisture content. [4][5][6][7] Bioscrubbers are reactors in which a pollutant-containing waste airstream is contacted with a scrubbing solution. The most promising bioscrubber setup is the biotrickling filter, in which absorption and biodegradation of the pollutants is achieved in a single packed bed column reactor.…”

The design and the construction of an actual 8.7-m 3 pilot/ full-scale biotrickling filter for waste air treatment is described and compared with a previous conceptual scale-up of a laboratory reactor. The reactor construction costs are detailed and show that about one-half of the total reactor costs ($97,000 out of $178,000) was for personnel and engineering time, whereas ~20% was for monitoring and control equipment. A detailed treatment cost analysis demonstrated that, for an empty bed contact time of 90 sec, the overall treatment costs (including capital charges) were as low as $8.7/1000 m 3 air in the case where a nonchlorinated volatile organic compound (VOC) was treated, and $14/ 1000 m 3 air for chlorinated compounds such as CH 2 Cl 2 . Comparison of these costs with conventional air pollution control techniques demonstrates excellent perspectives for more field applications of biotrickling filters. As the specific costs of building and operating biotrickling filter reactors decrease with increasing size of the reactor, the cost benefit of biotrickling filtration is expected to increase for full technical-scale bioreactors. IMPLICATIONSWith interest in biological techniques for air pollution control increasing, the true costs associated with the construction and operation of full-scale biological trickling filters are a fundamental criteria to evaluate the competitiveness of biotrickling filtration over more conventional air pollution control technologies. The present paper compares costs that were evaluated from a conceptual scaleup with actual numbers from the construction and operation of a pilot/full-scale biotrickling filter. The results are placed in a general perspective for the deployment of large biotrickling filters.

“…Typically biotechnology has not purposefully been used to treat other air emissions, but incidental air emissions removal often occurs in these same devices as they treat odors. Some researchers have seen as great as 90% air emission reductions in units specifically designed for air emission biotechnology applications [1][2][3]. A bioscrubber vendor also has data that shows both high odor (>95% odor removal) and lower air emissions removals (in the range of 40-83% removal that is VOC compound-dependent) [4].…”

“…Biofilters have been successfully tested and commercially installed in industrial applications to remove solvent VOC emissions such as toluene and ethanol [10]. Studies have indicated that biofilters may be more suitable for removing both VOC and odor emissions than other technologies, such as wet scrubbers [2].…”
