Performance and macrokinetic analysis of biofiltration of toluene and p-xylene mixtures in a conventional biofilter packed with inert material

► Knowledge of toluene and p-xylene interactions during in situ biofiltration to improve treatment of hydrophobic pollutants. ► Kinetic characterisation of VOC biodegradation and biomass production using real growth rates for in-situ biofiltration. ► The analysis of accumulated biomass in the packed bed by means of a carbon balance let to control and model the biofilter.
