Description The present work describes the biofiltration of mixture of n-propanol (as a model hydrophilic volatile organic compound
(VOC)) and toluene (as a model hydrophobic VOC) in a biofilter packed with a compost–woodchip mixture. Initially,
the biofilter was fed with toluene vapours at loadings up to 175 gm−3 h−1 and removal efficiencies of 70%–99% were
observed. The biofilter performance when removing mixtures of toluene and n-propanol reached elimination capacities of
up to 67 gtoluene m−3 h−1 and 85 gn-propanol m−3 h−1 with removal efficiencies of 70%–100% for toluene and essentially
100% for n-propanol. The presence of high n-propanol loading negatively affected the toluene removal; however, n-propanol
removal was not affected by the presence of toluene and was effectively removed in the biofilter despite high toluene loadings.
A model for toluene and n-propanol biofiltration could predict the cross-inhibition effect of n-propanol on toluene removal.
