چکیده
|
The removal of xylene vapors was studied in a biofilter packed with a new hybrid (scoria/compost) packing material atvarious inlet loads (il) and empty bed residence times (ebrt) of 90, 60, and 40s. the best performance was observed forebrt of 90s, where a removal efficiency of 98% was obtained under steady state condition for inlet xylene concentrationof 1.34 g m?3, while a maximum elimination capacity of 97.5 g m?3 h?1 was observed for il of 199.5 g m?3 h?1. carbondioxide production rates and the microbial counts for xylene-degraders followed xylene elimination capacities. overalllook to the results of this study indicates that the scoria/compost mixture could be considered as a potential biofiltercarrier, with low pressure drop (here < 4 mm h2o), to treat air streams containing vocs.
