“…The kinetic parameters were calculated to understand the kinetic behaviour of BTFs and the Michaelis-Menten equation was employed for this purpose. The maximum degradation rate (k 1 ) was 83.61 g m −3 s −1 (0.74 mmol L −1 min −1 ) for the BTF inoculated with a biomass suspension of Ralstonia pickettii L2 and an enriched activated sludge, whilst for the BTF inoculated only with the enriched activated sludge, k 1 = 36.64 g m −3 s −1 (0.33 mmol L −1 min −1 ); indicating that the introduction of Ralstonia pickettii L2 had a positive effect on the CB degradation rates of BTF [64]. Taking into account the results mentioned above and to the best of our knowledge, the degradation of CB in our anaerobic USPBR is the fastest biodegradation process ever reported.…”

“…The Michaelis-Menten model was used as the macrokinetic determination method and the kinetic parameters obtained were k 1 = 0.121 g m −3 s −1 (0.064 mmol L −1 min −1 ) and k 2 = 7.45 g m −3 (0.066 mmol L −1 ). Zhou et al [64] compared the performance and microbial communities of two differently inoculated biotrickling filters (BTFs) for treating CB. The kinetic parameters were calculated to understand the kinetic behaviour of BTFs and the Michaelis-Menten equation was employed for this purpose.…”

The present work explores the biodegradation of some emerging pollutants (EPs) in an anaerobic slowly-agitated up-flow packed-bed reactor (USPBR) filled with biological activated carbon (BAC). Chlorobenzene (CB) and 2,4-dichlorophenoxyacetic acid (2,4-D) were selected as volatile organic compounds (VOC) and major constituents of many pesticides. Experiments carried out in continuous operation showed that bioconversion up to 90% was achieved for CB and 2,4-D, at space times below 0.6 h and 1.2 h, respectively, at ambient temperature. Overall, removal rates of 0.89 g L−1 d−1 and 0.46 g L−1 d−1 were obtained for CB and 2,4-D, respectively. These results revealed that the degradation of CB and 2,4-D in this anaerobic configuration of bioreactor is an efficient and fast process. The Michaelis–Menten model properly describes the degradation process for CB. Above initial concentrations of 100 mg L−1, 2,4-D presented a considerable inhibitory effect over the biofilm. For this reason, a substrate inhibition factor was included in the Michaelis–Menten equation; the expanded model presented a good fitting to the experimental data, regardless of the inlet concentration. Therefore, USPBR-BAC combination showed to be a highly efficient system for the biodegradation of such compounds.

“…Among the treating methods, biotechnology is frequently used due to its advantages, such as no secondary pollutants and low operational and investment costs (Krzysztof et al, 2017;Zhou et al, 2016;Lebrero et al, 2014;Padhi and Gokhale, 2016). Bio-trickling filters (BTFs) are one of the effective ways treating VOCs or odour gases (Rachbauer et al, 2016;Goli et al, 2016).…”

Removal of n-butyl methacrylate from gas streams was studied in a bio-trickling filter packed with plastic ring coated with activated carbon fibre as a new material. This new material utilized the stronger adsorption capacity of the activated carbon fibre to help the microorganisms in the bio-system capture the contaminants more easily. The performance of the bio-trickling filter was investigated under various operational conditions to better understand the role of activated carbon fibre. Results of the comparison experiments indicated that the use of activated carbon fibre could greatly shorten the start-up time of BTF. The removal efficiency of the bio-trickling filter could maintained at higher than 95% under the empty bed residence time of 44s and inlet concentration of 400 mg•m-3 , with the corresponding removal loading of 54.3 g•m-3 •h-1 and 52.9 g•m-3 •h-1 , respectively. When the inlet loading of n-butyl methacrylate was lower than 42.7 g•m-3 •h-1 , a complete removal of n-butyl methacrylate could be achieved in the bio-trickling filter. The good performance of the bio-trickling filter demonstrated that the plastic ring coated with activated carbon fibre is an alternative as the packing material in the full application of the bio-trickling filter.
