“…30 The results obtained with the coupled system improved the performance considerably, so the RE increased up to 95% ( Figure 5) for an EBRT of 24 sec, and the VOC biotrickling emission was within the regulation requirements, with the VOC concentration level always below 40 mg-C/m 3 ( Figure 6, c and d, and Figure 7). These results were in good agreement with those previously reported for similar coupled systems (activated carbon prefilter plus biological reactor) on bench and industrial scales, 8,27,28 and it denoted that this coupled system was especially appropriate for the VOC removal of very uneven airstreams.…”

“…As previously reported, 8,27 to control the VOC concentration spikes arising from sudden variations in the paint operation, and to modulate the high and low pollutant loads, a filter of activated carbon can be used. Because biological treatments run better when inlet conditions are stable, the use of active carbon as a buffer unit usually improves the bioreactor performance.…”

“…8 • The limitations and problems of a field-scale BTF under cyclic and discontinuous operation, generally found in industrial setup, have been observed. 9 • In addition, the performance of a field-scale BTF for the treatment of styrene vapor released from a bathtub manufacturing process has been investigated with successful results and stable performance even under high variations of concentration, composition, and after a 3-day shutdown.…”

“…23,24 Successful reacclimation of toluene-degrading BTFs has been reported after periods of up to 9 days of non-use, 25 and ethyl acetate removal in a peat biofilter after a non-use period of as much as 15 days. 26 In addition, it has been reported 8,27,28 that a buffering carbon filter installed preceding biological reactor facilitates the treatment of sudden variations in concentration, spikes, and unstable loads of VOCs.…”

A 0.75-m 3 pilot-scale biotrickling filter was run for over 1 yr in a Spanish furniture company to evaluate its performance in the removal of volatile organic compounds (VOCs) contained in the emission of two different paint spray booths. The first one was an open front booth used to manually paint furniture, and the second focus was an automatically operated closed booth operated to paint pieces of furniture. In both cases, the VOC emissions were very irregular, with rapid and extreme fluctuations. The pilot plant was operated at an empty bed residence time (EBRT) ranging from 10 to 40 sec, and good removal efficiencies of VOCs were usually obtained. When a buffering activated carbon prefilter was installed, the system performance was improved considerably, so a much better compliance with legal constraints was reached. After different shutdowns in the factory, the period to recover the previous performance of the biotrickling reactor was minimal. A weekend dehydration strategy was developed and implemented to control the pressure drop associated with excessive biomass accumulation.

“…8 -12 Biotrickling filter technology has received increasing research attention. 7,[13][14][15][16] Many researchers adopted the process to treat the nitrogen oxides (NO x )-contaminated gas via denitrification. 17,18 This process relies on the maintenance of anoxic conditions so that NO x can be converted into inert N gas.…”

Abiotic and Biological Mechanisms of Nitric Oxide Removal from Waste Air in Biotrickling Filters

Nitric oxide (NO) may participate in the ozone layer depletion and forming of nitric acid. Abiotic and biological mechanisms of NO removal from waste gases were studied in a biotrickling filter. The abiotic NO removal rate in the biotrickling filter was estimated by a review of the literature. The abiotic and biological removals were also verified in the biotrickling filter. The result has shown that chemical oxidation and bionitrification were both involved in the NO removal. It was found that the NO removal in high concentration (ϳ1000 ppm or higher) was in large measure the result of abiotic removal in both gas-phase and liquid-phase reactions. When NO concentration is low (less than ϳ100 ppm), bionitrification was the main process in the NO removal process in the biotrickling filter.

The removal of a 1:1 by weight mixture of ethanol and ethyl acetate was studied in a gas phase biotrickling filter running under conditions that simulated industrial emissions from the flexographic sector, i.e. discontinuous loading (twelve hours per day and five days per week) and oscillating concentration of the inlet stream. Three sets of experimental conditions were tested in which empty‐bed residence time varied from 60 to 25 s (inlet loads from 50 to 90 g C m−3 h−1). The biotrickling filter reached a maximum elimination capacity of 48.5 g C m−3 h−1 (removal efficiency=68.9%) for an empty‐bed residence time of 40 s. A decrease in the residence time from 40 to 25 s adversely affected the elimination capacity (40.3 g C m−3 h−1, removal efficiency=46.6%). For the three tested residence times, outlet concentrations during pollutant feeding were above 100 mg C m−3 (EU legal limit for flexographic facilities). Then an activated carbon prefilter was installed to buffer the fluctuating concentration, enabling a more stable operation. The desorbed pollutant from the activated carbon during non‐feeding hours also served as an extra source of substrate, avoiding severe starvation. The use of the activated carbon prefilter with a volume 25 times lower than that of the bioreactor was shown to reach an average outlet emission concentration lower than 50 mg C m−3 operating the biotrickling filter at an empty‐bed residence time of 40 s, with a maximum elimination capacity of 59.6 g C m−3 h−1 (removal efficiency=92.0%).
