Abstract. Elimination of H2S in biogas was performed by bio-filtration, in which H2S degrading bacteria immobilized on the packing material inside a column. Bacteria was taken from the local area, while salak fruit seed was used as packing material because it has a quite large carbon content, porous and has a high water absorption capability. To obtain a quantitative description of the process, which is useful in the design of large-scale bio-filters, two kinetics models were proposed. Model 1 assumes intra-film gradient does not exist and the gas phase is quasi-steady-state. Model 2 assumes intra-film gradient exists and the gas phase is quasisteady-state. Comparison of the calculation results using the two models to the experimental data suggested the use of model 2. This conclusion is based on both the trend and the accuracy. The trend of model 1 is more conceivable. However, for rough calculation, model 1 could be used for the reason that it is simpler than model 2. The average absolute errors of model 1 and 2 are comparable, approximately 6 ppm. It can also be concluded that intra-film gradient significantly affects the overall rate processes, while the gas phase can be assumed to be quasi-steady-state.

“…Biogas is a gas produced by fermentation of organic material by microorganisms in anaerobic condition. This anaerobic process follows the stages of the hydrolysis, asidogenesis and methanogenesis [2]. According to Syed et al [3], biogas was composed of methane (CH4) 55-70%, carbon dioxide (CO2) 30-45% and hydrogen sulphide (H2S) 0-1.5%.…”

“…Particle size is not an important factor compared to other parameters such as pH and temperature. However, the size of the particles used affects the degradation and ultimately the biogas production rate [7,12,13]. The relationship between the amount of carbon and nitrogen present in organic materials is expressed by the carbon/nitrogen (C/N) ratio.…”

“…A pH range of 6.7 -7.4 is suitable for most methanogenic bacteria to function (Yadvika et al 2004;Hansen et al 1999;Gomec and Speece 2003). Jain and Mattiasson (1998) indicated that around this range of pH, the efficiency of methane production was at its optimum level.…”

“…The effective HRT is generally decreased with an increasing temperature of the slurry. For an optimum biogas yield, depending on the type of biomass and digestion temperature, a HRT of 30 to 50 days has been suggested (Yadvika et al 2004;Zennaki et al 1996;Garba 1996).…”

Doaguie, A.R., A. Ghazanfari and L.G. Tabil. 2012. Mesophilic anaerobic digestion of damask rose bagasse with different proportions of cattle manure. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 54:8.1-8.6. The flowers of damask rose plants (Rosa damascena Mill.) are utilized in hydro-distillation industries to produce concentrated rose water and essential oils. Rose bagasse is the main byproduct of these industries that are conventionally used as compost. The objective of this research was to investigate the potential and the kinetics of biogas production from this bagasse mixed with cattle manure with mass proportions of 95, 90, 85 and 80%. The anaerobic digestion process was carried out at two temperatures of 35 and 45°C for 30 days of hydraulic retention time. The daily pH, biogas production and generated methane were measured. The results indicated that biogas production rate increased with increase in the proportion of cow manure and temperature. Maximum cumulative biogas yield was 0.427 and 0.369 m 3 /kg of volatile solids in 45ºC and 35ºC, respectively. The volatile solids reductions in the various treatments ranged from 64.9 to 81.4%. The cumulative daily biogas yield for the treatments were modeled using a modified form of Gompertz equation with resulting R 2 values greater than 0.94.
