چکیده انگلیسی


- The effect two synthetic packing media on isoprene biofiltration was evaluated.
- The bioreactors showed 90% removal efficiency at 404 g m−3 h−1 inlet loading rate.
- Comparison showed superior efficacy of synthetic packing media over natural ones.
- Polyurethane foam was the most suitable packing media for isoprene abatement.

The efficacy of wood charcoal (WC) and nutrient-enriched wood charcoal (NWC) as biofilter packing media were assessed for isoprene biodegradation in a bioreactor comprising bioscrubber and a biofilter connected in series and inoculated with Pseudomonas sp. The bioreactors using WC and NWC exhibited >90% removal efficiency and around 369 g m−3 h−1 elimination capacity at around 404 g m−3 h−1 inlet loading rate. In both the bioreactors, the biofilter component showed better degradation capacity compared to the bioscrubber unit. The kinetic parameters, maximum elimination capacity, ECmax; substrate constant, Ks and ECmax/Ks for Michaelis-Menten model were evaluated. The lower Ks for the WC packed bioreactor indicated that ECmax achieved, was faster compared to others, while higher ECmax and ECmax/Ks for the NWC packed bioreactor suggests its superiority in isoprene abatement in the continuous mode. A comparison of the available published information on biofiltration of isoprene reflected polyurethane foam as the superior packing media.
