“…Systems are compact and mobile and can be configured to treat a wide range of feed stream flow rates and compositions. The separation of aromatic VOCs has been investigated over various gas membranes (Dingemans et al, 2008;Obuskovic et al, 2003;Sohn et al, 2000;Wang et al, 2005). However, there is scarce studies on utilization of gas membrane separation in maintain biofilter performance during transient VOC loadings.…”

a b s t r a c tBiofiltration for volatile organic compound control in waste gas streams is best operated at steady contaminant loadings. To provide long-term stable operation of a biofilter under adverse contaminant feeding conditions, an integrated bioreactor system with a gas separation membrane module installed after a biofilter was proposed for styrene treatment. Styrene was treated effectively, with average styrene effluent concentrations maintained at less than 50 mg m À3 and a total removal efficiency of over 96% achieved when the biofiltration column faced fluctuating loads. The maximum elimination capacity of the integrated bioreactor system was 93.8 g m À3 h À1, which was higher than that obtained with the biofiltration column alone. The combination of these two processes (microbial and chemical) led to more efficient elimination of styrene and buffering of the fluctuating loads. The factors on gas membrane separation, microbial characteristics in the integrated bioreactor and membrane fouling were also investigated in this study.
