“…4 Still another set-up composed of a bioscrubber-biofilter in series was evaluated for the treatment of odours released at composting facilities. 151 The exact nature of the pollutants was not reported, but it was observed that only a small fraction, less than 30%, of the pollutants was removed in the bioscrubber. Most of the remaining odour load was eliminated in the biofilter.…”

Bioprocesses have been developed as relatively recent alternatives to conventional, non-biological technologies, for waste gas treatment and air pollution control in general. This paper reviews major biodegradation processes relevant in this field as well as both accepted and major innovative bioreactor configurations studied or used nowadays for the treatment of polluted air, i.e. biofilters, one-and two-liquid phase biotrickling filters, bioscrubbers, membrane bioreactors, rotating biodiscs and biodrums, one-and two-liquid phase suspended growth bioreactors, as well as hybrid reactor configurations. Some of these bioreactors are being used at full-scale for solving air pollution problems, while others are still at the research and development stage at laboratory-or pilot-scale.

“…It has to be taken into account that possible effects derived from masking or synergies between the evaluated compounds are not considered, and that the total odour units (OU) determined by olfactometry could differ in a certain way [5][6][7][8]. However, it has also to be considered that OU calculated using the presented methodology in a previous study were in the range of 1200-28,000 OU [3], in accordance with OU calculated using dynamic olfactometry (5000-30,000 OU m -3 ) in similar facilities [9,10]. Additionally, several studies have demonstrated good correlations between olfactometrically determined OU and VOC concentrations [5,10,11].…”

“…They also found that the bed becomes more acidic with the production of sulfuric acid as a result of biodegradation of H 2 S and that this influenced the MEK biodegradation bacteria. Schlegelmilch et al (2005) determined terpene compounds such as a-pinene, camphene, b-phellandrene, b-pinene, b-myrcene, 3-carene, limonene, and others in waste gas from composting process. They presented odor reduction efficiencies of biological waste gas treatment systems at various scales by carrying out experiments with a combination of different biofilter materials.…”

Composting is widely used for the treatment of solid organic wastes; however, emissions from composting are becoming a threat to humans due to the release of toxic volatile organic compounds (VOCs). VOCs from composting operations are characterized by high flow rates and, normally, low pollutant concentration. Typical VOCs include a large amount of terpenes ($65% of total VOCs). This study was to investigate the efficiency of biofiltration in controlling terpene emissions from composting operations using a laboratory-scale unit. The performance of a biofilter was investigated as a function of inlet flow rate, inlet concentration, and bed length/bed diameter (L/D) ratio of bed. At the lowest total inlet flow rate, removal efficiency of limonene and b-pinene was more than 90%. With the decrease in inlet concentration and increase in L/D ratio, the removal efficiency was effectively increased. Removal efficiency of more than 85% for Limonene and 45% for b-Pinene was attained at a loading rate of 55 g/m 3 -hr. The maximum elimination capacity was found for 109.7 g/m 3 -hr for limonene and 10.3 g/m 3 -hr for b-pinene at a critical loading of 150.1 g/m 3 -hr. Based on this study, the compost bed could function as a biofilter for controlling terpene odors during the composting process.Implications: The purpose of this research project is to investigate the efficiency of biofiltration in controlling limonene and b-pinene emissions from composting operations using a laboratory scale. In addition, the performance of a biofilter as a function of inlet flow rate, inlet concentration, and L/D ratio of bed was evaluated. Establishing a nexus between the operational parameters and efficiency would be useful in design and operation of compost bed as a biofilter for controlling terpene odors during the composting process.
