“…For a 3-m 3 biotrickling filter, an investment of $184,000 was estimated and overall treatment costs were evaluated at $62/1000 m 3 of air treated. 13 In the present paper, the actual design and construction of an 8.7-m 3 pilot/full-scale biotrickling filter are described and the real treatment costs are discussed. The design of the reactor was based on the same design criteria and principles described previously.…”

“…The reason is that in biotrickling filters, environmental conditions can be better controlled. 8,10,12,13 Because full-scale applications of biotrickling filters are still relatively rare, there is a lack of information on the true costs associated with the construction and operation of biotrickling filters at industrial scale. Recently, the comparative scale-up of two innovative reactor setups for biological waste air treatment was described.…”

“…Recently, the comparative scale-up of two innovative reactor setups for biological waste air treatment was described. 13 The scale-up was essentially a design exercise using the results from a bench-scale biotrickling filter and three-phase airlift reactors to dimension technical-scale bioreactors. Both investment costs and operating costs were evaluated for the treatment of CH 2 Cl 2 -contaminated airstreams.…”

“…8 Biotrickling filters offer promise for the elimination of volatile organic compounds (VOCs) and chlorinated VOCs, odors, and reduced sulfur compounds. [9][10][11][12][13] At this time, only a few full-scale biotrickling filters have been implemented for industrial usage. 14,15 The main drawbacks of biotrickling filters are their higher costs than biofilters and possible clogging of the reactor over time by growing biomass.…”

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.

“…In general, increased liquid and gas velocities result in higher mass transfer, resulting in k L a values of up to 0.24 s −1 for bubble columns (Bredwell et al 1999), although such measures are accompanied with increased power demands, which is economically/commercially unattractive. Differences in treatment costs as evaluated by Zuber et al (1997) revealed a 50% cheaper treatment with a biotrickling filter compared to a gas lift reactor (Zuber et al 1997). When selecting a biotrickling filter, the maximal flux of CO could be determined assuming a k L a of 0.015 s −1 as determined for this reactor type in CO conversions at 37°C (Klasson et al 1992).…”

Desulfotomaculum carboxydivorans, recently isolated from a full-scale anaerobic wastewater treatment facility, is a sulfate reducer capable of hydrogenogenic growth on carbon monoxide (CO). In the presence of sulfate, the hydrogen formed is used for sulfate reduction. The organism grows rapidly at 200 kPa CO, pH 7.0, and 55°C, with a generation time of 100 min, producing nearly equimolar amounts of H 2 and CO 2 from CO and H 2 O. The high specific CO conversion rates, exceeding 0.8 mol CO (g protein) −1 h −1 , makes this bacterium an interesting candidate for a biological alternative of the currently employed chemical catalytic water-gas shift reaction to purify synthesis gas (contains mainly H 2 , CO, and CO 2 ). Furthermore, as D. carboxydivorans is capable of hydrogenotrophic sulfate reduction at partial CO pressures exceeding 100 kPa, it is also a good candidate for biodesulfurization processes using synthesis gas as electron donor at elevated temperatures, e.g., in biological flue gas desulfurization. Although high maximal specific sulfate reduction rates (32 mmol (g protein) −1 h −1 ) can be obtained, its sulfide tolerance is rather low and pH dependent, i.e., maximally 9 and 5 mM sulfide at pH 7.2 and pH 6.5, respectively.

Two protozoan species as well as an uncharacterized protozoan consortium were added to a toluene‐degrading biotrickling filter to investigate protozoan predation as a means of biomass control. Wet biomass formation in 23.6‐L reactors over a 77‐day period was reduced from 13.875 kg in a control biotrickling filter to 11.795 kg in a biotrickling filter enriched with protozoa. The average toluene vapor elimination capacity at 1 g/m3 toluene and 64 m3/(m3 · h) was 31.1 g/(m3 · h) in the control and 32.2 g/(m3 · h) in the biotrickling filter enriched with protozoa. At higher toluene inlet concentrations, toluene degradation rates increased and were slightly higher in the biotrickling filter enriched with protozoa. The lower rate of biomass accumulation after the addition of protozoa was due to an increase of carbon mineralization (68% as compared to 61% in the control). Apparent biomass yield coefficients in the control and enriched trickling filter were 0.72 and 0.59 g dry biomass/g toluene, respectively. The results show that protozoan predation may be a useful tool to control biomass in biotrickling filters, however, further stimulation of predation of the biomass immobilized in the reactor is required to ensure long‐term stability of biotrickling filters. © 1999 John Wiley & Sons, Inc.
