87. Styrene degradation in perlite biofilter: the overall performance characteristics and dynamic response - Halecky, Martin; Paca, Jan; Gerrard, Andrew Mark; Soccol, C. R.
Styrene�s degradation in a perlite biofilter including the long-term operation, dynamic response to step-changes in inlet concentration and non-use periods were tested. The study was performed in a bench-scale biofilter with ID 100 mm and a bed height of 1 m. Perlite with a particle size of 2 � 4 mm was used as a packing material. An enrichment mixed culture was immobilized on the packing. The inoculum was obtained from a styrene biofilter. Two different loading conditions were tested: (1) Loading with a high inlet concentration and a high residence time. (2) Loading with a low inlet concentration and...

89. Performance evaluation of fungal biofilters packed with Pall rings, lava rock, and perlite for a-pinene removal - Yaomin, Jin; Veiga Barbazán, María del Carmen; Kennes, Christian
The most suitable packing material for biofiltration of a-pinene was selected among Pall rings, lava rock, and perlite. In the present study, several biofilters fed a-pinene-polluted air were inoculated with a new fungal isolate of Ophiostoma stenoceras. The biofilters were packed either with lava rock or Pall rings alone or with a mixture of perlite and Pall rings. During the approximately 9 months operation, a-pinene�s removal efficiency, pressure drops, pH dependence and removal profile were evaluated. a-Pinene removal efficiencies were above 93.8%, 79.4% and 58.6% at an inlet loading rate of 100 g.m-3.h-1 in the biofilters packed with Pall rings,...

91. Characterization of a biotrickling filter treating methanol vapours - Avalos Ramírez, A.; Jones, J. P.; Heitz, M.
The aim of this research is to characterize a biotrickling filter (BTF) treating methanol vapour emissions. The parameters studied were the nitrogen concentration in the nutrient solution and the empty bed residence time (EBRT). The effect of continuously recycling the nutrient solution was also analyzed. At nitrogen concentrations as low as 0.001 gN L-1, the BTF presented removal efficiencies higher than 70 % for an inlet load of 110 g m-3 h-1. A nitrogen concentration of 0.005 gN L-1 was used to study the effect of EBRT and the continuous recirculation of nutrient solution. At a constant methanol inlet concentration...

92. Performance of peat biofilters treating ethyl acetate and toluene mixtures under non-steady-state conditions - Álvarez-Hornos, F. J.; Gabaldón, C.; Martínez-Soria, V.; Marzal Doménech, Paula; Penya-Roja, J. M.
This paper presents the response of peat biofilters to loading changes corresponding to industrial practices such as overnight and weekend shutdowns, intermittent emission or inlet concentration peaks. Three laboratory-scale reactors fed with air contaminated with ethyl acetate, toluene or a 1:1 mixture of ethyl acetate and toluene were operated under 65 g m-3 h-1 inlet load and 60 s EBRT during 16 h/day, 5 days/week. Dynamic behavior after feed resumption after night and weekend closures showed a 1-2 h period of transient response to recover stable CO2 production values. No increase in VOC emission was observed, except for biofilters treating...
