Abstract The biological removal of hydrogen sulfide in biogas is an increasingly adopted alternative to conventional physicochemical processes because its economic and environmental benefits. In this study, a real-scale biotrickling filtration (BTF) process packed with polypropylene carrier was used investigate the high concentrations H2S from anaerobic digester. results show that entirely remo...

The effect of the partition coefficient on simulation operation a biotrickling filter treating mixture sulfur compounds was analyzed to evaluate pertinence using Henry’s law in determining its removal capacity. analysis consisted that bio-oxides hydrogen sulfide (H2S), dimethyl (DMS), methyl mercaptan (MM) and disulfide (DMDS) different types models for coefficient: pure water, adjusted from ex...

Methane anthropogenic diffuse emissions (below 1 % vv) are important, with a significant contribution of the waste management sector (estimatedaround 21%). Since biological alternatives are especially promising for the treatment of a wide number of gaseous pollutants, a biotrickling filter packed with polyurethane foam was employed to study the abatement of methane (0.2 – 1 % vv) in air emissio...

Laboratory scale biological trickling filters and three-phase airlift bioreactors have been studied for the elimination of methylene chloride (or dichloromethane) vapors from waste air, and the results used herein for the design of small industrial-scale reactors. The conditions chosen for scale-up were an air flow rate of 100 m3 h-1, a methylene chloride inlet concentration of 2 g m-3, and a t...

The present work investigated for the first time feasibility of anoxic biodegradation siloxanes (hexamethyldisiloxane, L2; octamethyltrisiloxane, L3; octamethylcyclotetrasiloxane, D4; and decamethylcyclopentasiloxane, D5) in a two-phase partitioning biotrickling filter (TP-BTF) using silicone oil as organic phase. influence ratio inlet concentration were also evaluated. highest removals obtaine...

Biological removal of reduced sulfur compounds in energy-rich gases is an increasingly adopted alternative to conventional physicochemical processes, because of economical and environmental benefits. A lab-scale biotrickling filter reactor for the treatment of high-H(2)S-loaded gases was developed and previously proven to effectively treat H(2)S concentrations up to 12,000 ppm(v) at gas contact...
