“…Wright et al found that acclimation in compost biofilters is faster in treating gasoline vapors when the biofilters are inoculated with culture grown on gasoline (Wright et al, 1997). Leson and Smith reached a similar conclusion, suggesting that inoculation hastens acclimation but does not affect the ultimate removal efficiency (Leson and Smith, 1997).…”

a b s t r a c tMicroorganisms in a biofilter play important roles in the gas contaminants treatment process. In this study, thermophilic desulfurization bacteria were inoculated in a thermophilic biofilter for SO 2 treatment after acclimation and enrichment. Molecular biology techniques were applied to detect temporal variation of microbial population during acclimation and biofilter start-up period. The acclimation temperatures were 50, 55, and 60 C. Desulfurization bacteria dominated the enrichments. During acclimation, desulfurization bacteria and thermophilic bacteria increased from 36.84% to 78.95%e52.94% and 88.24%, respectively. In addition, the microbial diversity indices of these enrichments decreased with time. Substrate species and acclimation temperature influenced the microbial structure of the enrichments. The thermophilic biofilter inoculated with enrichments could achieve a rapid start-up, and over 80% of removal efficiency could be obtained within two weeks. The maximum elimination capacity was 38.71 g m À3 h À1 at 152 mg m À3 inlet concentration. The total sulfur bacteria proportion increased obviously during the start-up period. Moreover, desulfurization bacteria that originally existed in inocula, e.g., Pseudomonas putida, Bacillus thioparans, Microbacterium sp., and Thermoanaerobacteriaceae, were abundant in the thermophilic biofilter for SO 2 removal.

“…Yet only a few papers on the biofiltration of gasoline and other diverse hydrocarbon mixtures are available (Leson and Smith, 1997;Barton et al, 1997;Wright et al, 1997;Morales et al, 1998;Namkoong and Park, 2003;Namkoong and Park, 2004;Paca et al, 2007). Even fewer studies have tackled the interactions of aliphatic and more biodegradable aromatic compounds in their mixtures (Schindler and Friedl, 1995;Holubar et al, 1999;Lu et al, 2001;Kim, 2003;Hassan and Sorial, 2010;Halecky et al, 2012).…”

“…The intermediate fraction, kerosene or jet fuel, contains lighter alkanes than diesel, allowing the fuel to remain in the liquid state at lower temperatures. All gasoline and diesel components are considered biodegradable, that is., amenable to biofiltration, a technology that presents a viable alternative to traditional physical and chemical air treatment methods for the remediation of a number of substrates (Leson and Smith, 1997;McGrath et al, 1997;Devinny et al, 1999).…”

The ability of a biofilm to switch between the mixtures of mostly aromatic and aliphatic hydrocarbons was investigated to assess biofiltration efficiency and potential substrate interactions. A switch from gasoline, which consisted of both aliphatic and aromatic hydrocarbons, to a mixture of volatile diesel n-alkanes resulted in a significant increase in biofiltration efficiency, despite the lack of readily biodegradable aromatic hydrocarbons in the diesel mixture. This improved biofilter performance was shown to be the result of the presence of larger size (C 9 -C 12 ) linear alkanes in diesel, which turned out to be more degradable than their shorter-chain (C 6 -C 8 ) homologues in gasoline. The evidence obtained from both biofiltration-based and independent microbiological tests indicated that the rate was limited by biochemical reactions, with the inhibition of shorter chain alkane biodegradation by their larger size homologues as corroborated by a significant substrate specialization along the biofilter bed. These observations were explained by the lack of specific enzymes designed for the oxidation of short-chain alkanes as opposed to their longer carbon chain homologues.Implications: Biological removal of petroleum hydrocarbons from contaminated air has not become a widely used technology due to its low efficiency. This paper presents the analysis of this problem using bench-scale experiments and provides several reasons for the low biodegradation efficiency of gasoline. The results reported suggest that gasoline removal efficiency strongly depends on the substrate composition, with aromatic hydrocarbons being removed preferentially. The study also opens up a new perspective for the efficient biofiltration of diesel hydrocarbons as opposed to gasoline, as higher molecular weight n-alkanes of diesel were removed readily. By contrast, low-molecular-weight n-alkanes of gasoline turned out to be poor substrates for biofiltration, and the biological reasons for this phenomenon were suggested.

“…The hydrocarbon load produced from the SMZ regeneration step is far below this value and thus high removal efficiencies are expected. In fact, VPBs were originally developed to treat waste gas streams containing low concentrations of VOCs and this is considered the ideal application for the VPB technology (Leson and Winer, 1991;Leson and Smith, 1997;van Groenestijn and Hesselink, 1993.). Several VPB configurations are possible for the SMZ application including a biofilter configuration with a stationary liquid film containing nutrients and biomass.…”

Treatment of Produced Waters Using a Surfactant Modified Zeolite/Vapor Phase Bioreator System

Co-produced water from the oil and gas industry is by some estimates the largest single waste stream in the country, aside from nonhazardous industrial wastes.Characteristics of produced water include high total dissolved solids content, dissolved organic constituents such as benzene and toluene, an oil and grease component, and chemicals added during the oil-production process. While most of the produced water is disposed via reinjection, some of them must be treated to remove organic constituents before the water is discharged. An efficient, cost-effective treatment technology is needed to remove these constituents. Surfactant-modified zeolite (SMZ) has been used successfully to treat contaminated ground water for organic and inorganic constituents.In addition, the low cost of natural zeolites makes their use attractive in water-treatment applications. Our previous DOE research work (DE-AC26-99BC15221) demonstrated that SMZ could successfully remove BTEX compounds from the produced water. In addition, SMZ could be regenerated through a simple air sparging process. The primary goal of this project is to develop a robust SMZ/VPB treatment system to efficiently remove the organic constituents from produced water in a cost-effective manner. to treat the off-gas from the SMZ regeneration process. These columns will be used both in the laboratory and in the proposed field testing to be conducted next year. Innocula for the columns that degrade all of the BTEX columns have been developed.
