Co-treatment of single, binary and ternary mixture gas of ethanethiol, dimethyl disulfide and thioanisole in a biotrickling filter seeded with Lysinibacillus sphaericus RG-1

Modeling the effects of biomass accumulation on the performance of a biotrickling filter packed with PUF support for the alkaline biotreatment of dimethyl disulfide vapors in air

“…In this sense the observed DMDS elimination capacities during the experiments reported here ( fig. 3), are comparable with previous reports of DMDS treatment in BTF at neutral pH (Ramirez et al 2011, Wan et al 2011). However it is important to consider that in our case the effective gas residence time was reduced approximately to half of that initially calculated (40 s), due to biomass accumulation and liquid hold-up presence.…”

Pollution profiles, health risk of VOCs and biohazards emitted from municipal solid waste transfer station and elimination by an integrated biological-photocatalytic flow system: A pilot-scale investigation

“…However, some conventional physico-chemical techniques, such as masking, incineration, absorption and adsorption are often unsatisfactory because these hazards may still not be fully destroyed [6]. Comparatively, biological treatment has been validated as a promising technology for odoriferous VOCs removal from gas due to its relatively low investment and operating costs, small energy requirements as well as efficient conversion of biodegradable contaminants to harmless end-products [7][8][9]. A number of VOCs were found to be biologically degraded using different bioreactors, for example synthetic H 2 S and VOCs mixture (butanone, toluene and ␣-pinene) by a biofilter and an air diffusion bioreactor [10], trichloroethylene and toluene mixture by a hollow fiber membrane reactor [11], single, binary and ternary mixture gas of ethanethiol, dimethyl disulfide and thioanisole by a biotrickling filter (BTF) [12,13].…”

Efficient bio-deodorization of thioanisole by a novel bacterium Brevibacillus borstelensis GIGAN1 immobilized onto different parking materials in twin biotrickling filter

“…For instance, ethanethiol and dimethyl disulfide could be effectively biodegraded by a new Lysinibacillus sphaericus RG-1 and Bacillus cereus GIGAN2 (Liang et al, 2015), respectively. Further, extensive literatures were also focused on using BTF to control various odorants, such as inorganic odor H 2 S (Mannucci et al, 2012;Zhang et al, 2009), and organic odor like dimethyl sulfide, ethanethiol, dimethyl disulfide, and methanethiol (Arellano-Garcia et al, 2009;Lebrero et al, 2012;Wan et al, 2011b). However, only two papers were focused on the abatement of thioanisole-containing odorous vapors by BTF inoculated with commercialized B350 or self-isolated L. sphaericus RG-1 (Wan et al, 2011a,b).…”
