“…Most biofilter studies have been operated at room temperature of 20-35 • C, typical of mesophilic microorganisms [6]. However, many industrial streams emitting from the processes such as pulp and paper manufacturing, coating process (i.e.…”

“…Highly enriched sludge from a membrane bioreactor treating landfill leachate was used as inoculum for these two filters. Although similar loads were used in both filters, the acclimation period was much higher in the case of the thermophilic biotrickling filters, around 25 days to reach removal efficiency exceeding 80% at EBCT of 100 seconds, and shorter in the case of mesophilic system, around 17 days to reach removal efficiency exceeding 98% at the same EBCT (Luvsanjamba et al, 2008). He also employed the same inoculum to remove mixture of isobutyraldehyde and 2-pentanone from high temperature inlet air (52°C) and from ambient temperature inlet air (22°C).…”

Experiments were carried out to test the capacity for a laboratory-scale biofilter operated at an elevated temperature level (∼50°C) to remove an air stream containing β-caryophyllene, a naturally occurring sesquiterpene of environmental concern emitted from wood-related industrial facilities. A water jacket was used to maintain high temperatures in a laboratory-scale biofilter. Inocula, pollutant loading and nutrient supply rate effects were evaluated over 84 days of biofilter operation. The start-up process took over two months when citrus peels were used as inocula while a relatively short start-up period was achieved after introducing forest compost products. While using a sparged-gas bioreactor to cultivate an enrichment culture for 97 days, removal efficiencies in excess of 80% were observed after 18 days. At empty bed contact times of 50 s and at a pollutant loading rate of 3.05 mg C/L/hr, removal efficiency levels reached 90% and the elimination capacity level reached 2.29 mg C/L/hr, corresponding to an elimination capacity of 2.60 mg β-caryophyllene/L/hr. Collectively, these results demonstrate that β-caryophyllene can be successfully removed from contaminated air using a biofilter operated at a high temperature (∼50°C), expanding the temperature range within which biofilters are known to biodegrade sesquiterpenes.

“…An additional explanation could be related to the increase in the temperature of the circulation water of the BTF that might have created favourable conditions in the BTF. However, this hypothesis is not supported by the scarce number of scientific papers in the literature [27]. To prove this hypothesis, the concentration of DMS should be measured in B.…”

A chemical scrubber followed by a biotrickling filter (BTF) was integrated in the air treatment line of a composting plant, originally equipped with an open-bed biofilter. Such integration is motivated by the poor performance of the biofilter in the removal of odorants like ammonia (NH3), sulphides and volatile organic compounds (VOCs). The scrubber and BTF units were monitored during two summer periods in two consecutive years (08.
