“…It follows that biodegradation could only occur in compounds that are both biodegradable and readily adsorbable. These results are in agreement with that obtained by Pandey et al [28] who studied the biofilter for the treatment of waste gas containing diethyldisulphide for a period of more than two months, and the results of the performance indicated that diethyldisulphide removal efficiency was 94 ± 5%. Babbitt et al [29] also used activated carbon in biofilter to remove methanol from air, with a removal efficiency of 100%.…”

Biofiltration technology has been recognized as a promising biotechnology for treating the volatile organic compounds (VOCs) present in polluted air. This study aims to investigate the performance of a biofiltration system of Streptomyces griseus sp. DSM-40759 immobilized on activated carbon (PICA S23) towards the adsorption and degradation of toluene vapour as well as to regenerate the activated carbon in situ. The batch studies were performed using nutrient agar medium and basal salt medium (BSM) for microbial growth. Initially the pre-cultures were incubated at a temperature of 28°C on a rotary shaker at 150 rpm. After two days, the strain S. griseus DSM-40759 was immobilized on a known weight of activated carbon (12 g). The results of biofilter performance showed three different stages with a quick adsorption phase with approximately 95% of toluene removal after 70 min, a slow biotransformation phase by immobilized cells. In the later, the removal efficiency decreased significantly with the extension of time and reached 60% during this stage. Moreover, a final quick removal phase by the immobilized cells had an average removal efficiency of toluene around 95% after 500 min. The toluene degradation was found to be more than 84% after the second cycle and the biofilter was still capable of removing additional toluene. Thus, the results demonstrated the feasibility and reusability of a new biofilter system for toluene removal as well as extending the activated carbon's capacity and this could be a potential solution to reuse the activated carbon in industrial application.

“…Additionally, with biological treatment under optimal conditions, the biodegradable contaminants can be converted to harmless endproducts without the accumulation of intermediates or dead-end metabolites [12]. A number of VOSCs, such as methanethiol [13,14], dimethyl disulfide [15,16], diethyl disulfide [17], and dimethyl sulfide [18] have been found to be biologically degradable. However, ethanethiol cannot be effectively degraded in anaerobic conditions [19].…”

“…At the same time, the emitted compounds are often malodorous. The main approaches to limiting atmospheric emissions are based on the encapsulation of technological processes and fume removal through air extraction, followed by further neutralization using a variety of operations. − Such processes often result in the formation of effluents, which should be subjected to further treatment to reduce their toxicity and malodorousness. Analytical procedures determining the effectiveness of VOC removal processes and quantifying their emissions to the atmosphere play an important role in such efforts. − …”

This article presents the results of investigations on the use of headspace analysis and gas chromatography with pulsed flame photometric detection (HSA-GC-PFPD) to evaluate the effectiveness of oxidation of postoxidative effluents from the production of bitumens. Samples of effluents from the bitumen oxidation unit were used in the experiments. In addition, the kinetics of effluent oxidation was also investigated. The content of volatile sulfur compounds (VSCs) was determined using HSA-GC-PFPD. The results were correlated with chemical oxygen demand (COD). The changes in concentration of individual volatile sulfur compounds in the course of effluent oxidation were measured, which enabled the determination of the order of the oxidation reactions. The usefulness of the determination of VSCs in the headspace as a reliable technique for evaluating the reduction in emissions of volatile malodorous compounds was demonstrated. The developed method is also useful for process control of the oxidation of postoxidative effluents. The procedure ensures an objective evaluation of the effectiveness of the removal of volatile sulfur compounds from postoxidative effluents. The experimental results revealed that the effectiveness of the oxidation of organosulfur compounds was much higher than that of other classes of organic compounds. Furthermore, the order of oxidation reactions along with the rate constants of thiophenol, p-thiocresol, and hydrogen sulfide were determined. An advantage of the developed procedure is that it can be automated.
