“…It has been shown that an inoculation protocol and a continuous supply with actively growing Hyphomicrobium VS can strongly influence the biofilm microbial community of a biotrickling biofilter, allowing very rapid start-up and prolonged dimethyl sulfide-degrading activity. 26 Rhodococcus erythropolis, which contains a large set of enzymes capable of performing various bioconversions or degradations, is an excellent candidate in the same field. 27 More specifically, an alcohol dehydrogenase has been purified from R. erythropolis, 28 and the activity of whole cells of Rhodococcus ruber has been employed as an efficient biocatalytic redox system for cofactor regeneration of the NADH/NAD + system using ethanol as substrate.…”

BACKGROUND: In the framework of biological processes used for waste gas treatment, the impact of the inoculum size on the start-up performance needs to be better evaluated. Moreover, only a few studies have investigated the behaviour of elimination capacity and biomass viability in a two-phase partitioning bioreactor (TPPB) used for waste gas treatment. Lastly, the impact of ethanol as a co-substrate remains misunderstood.

“…Biodegradation of SO 2 was documented in a recent publication (Zhang et al, 2015) where a biofilter, operating with EBRT of 18 s degraded SO 2 in an air stream at 100-200 ppm, showing a removal efficiency > 93% and a maximum elimination rate of 50.67 g m -3 h -1 . DMS removal was the object of a study on a BTF application operating with EBRT of 120 s, which achieved a removal efficiency > 90% and a maximum elimination rate of 7.2 g m -3 h -1 , from an initial concentration of 117 ppm (Sercu et al, 2005 …”

A pilot plant for the treatment of Sulphur-based odorous gases was installed in a line of a phosphoric acid plant located in Skhira, Tunisia. The air pollution control system train consisted of a first stage, including a chemical scrubber operating with an alkaline solution containing caustic soda, followed by a two-stage biotrickling filter (BTF) filled with Mytilus edulis shells. This study evaluated the performance of the dual-stage BTF in removing hydrogen sulphide (H 2 S), sulphur dioxide (SO 2 ) and dimethyl sulphide (DMS) from the phosphoric acid reactor's exhaust air current. Concentrations of H 2 S, SO 2 and DMS at the inlet of the two-stage BTF were 10-30 ppm, < 1-20 ppm and 16-30 ppm, respectively. All of the respective concentrations at the outlet of the biological step were < 1 ppm, except for the H 2 S in the outlet during the first day of operation (10 ppm). Removal efficiencies were generally higher than 95% for all compounds, and remained high even with an increase of the off-gas flow rate. Mass-removal capacity was at least 2.0 g m -3 h -1 , 0.5 g m -3 h -1 and 6.2 g m -3 h -1 , for H 2 S, SO 2 and DMS, respectively. The removal efficiencies of the process were satisfactory, especially considering the already low inlet concentrations, due to the high quality of the raw phosphate used.Keywords: hydrogen sulphide, odor abatement, phosphoric acid production. Remoção de odores de compostos sulforosos de gases industriais por filtros biotrickling RESUMOUma estação piloto para o tratamento de gases odoríferos à base de enxofre foi instalado em uma linha de uma fábrica de ácido fosfórico localizada em Skhira (Tunísia). A estação piloto é constituída por um primeiro estágio que inclui um scrubber químico que usa uma e 6,2 g m -3 h -1 , respectivamente. Apesar das baixas concentrações de entrada, principalmente devidas à alta qualidade do fosfato bruto, a instalação piloto mostrou resultados satisfatórios, tendo em vista o seu redimensionamento e a sua aplicação a uma escala maior.Palavras-chave: abatimento de odores, ácido sulfídrico, produção de ácido fosfórico.

International audienceBACKGROUND: This study deals with the potential of biological processes combining biofiltration and a biotrickling filter to treat a mixture of sulphur reduced compounds (SRC) including dimethylsulfide (DMS), dimethyldisulfide (DMDS) and hydrogen sulphide (H2S). The first step in this work is to evaluate the influence of pH on SRC biodegradation in microcosms seeded with planktonic biomass from activated sludge of a rendering facility. In a second step, for each tested pH, evaluation of the influence of pH on total bacterial community diversity and structure has been investigated using denaturing gradient gel electrophoresis (DGGE). RESULTS: At pH 7 and 5, H2S, DMS and DMDS were completely removed. In return, the abatement of DMS and DMDS is low, around 20%, for pH 3 and pH 1 microcosms. The selective pressure imposed in the microcosms (concentration and pH) is sufficient to influence strongly the community diversity and composition. The inoculum community seems to make a significant contribution to the 67-day community in the considered pH microcosms. CONCLUSION: These results suggest that distinct communities from different inocula can achieve high and stable functionality. The results obtained provide relevant information for improving the treatment of different SRC using biotrickling filter/biofilter combination. Copyright (c) 2012 Society of Chemical Industr
