Performance evaluation of a scoria-compost biofilter treating xylene vapors
The removal of xylene vapors was studied in a biofilter packed with a new hybrid (scoria/compost) packing material at various inlet loads (IL) and empty bed residence times (EBRT) of 90, 60, and 40s. The best performance was observed for EBRT of 90s, where a removal efficiency of 98% was obtained under steady state condition for inlet xylene concentration of 1.34 g m(-3), while a maximum elimin...
متن کاملBiodegradation of BTX Vapors In a Compost Medium Biofilter
Removal of benzene, toluene, and xylenes (BTX) from waste gases was studied in a 50-L laboratory-scale biofilter (25.2 cm I.D. and 100 cm H). A commercial blend of composted chicken manure and peat moss was used as the filter bed. The composted organic material was selected due to its relatively high microbial diversity and for its nutritive value (i.e. presence of N-sources and essential miner...
متن کاملA biofilter for treating toluene vapors: performance evaluation and microbial counts behavior.
A lab-scale biofilter packed with mixed packing materials was used for degradation of toluene. Different empty bed residence times, 148.3, 74.2 and 49.4 s, were tested for inlet concentration ranging from 0.2 to 1.2 g/m(3). The maximum elimination capacity of 36.0 g/(m(3) h) occurred at an inlet loading rate of 45.9 g/(m(3) h). The contribution of the lower layer was higher than other layers an...
متن کاملChanges in physical properties of a compost biofilter treating hydrogen sulfide.
A technique is presented that can be used to estimate the changes in physical structure in a natural biofilter packing medium, such as compost, over time. The technique applies information from tracer studies, grain size distribution, and pressure drop analysis to a model that estimates the number of channels, average channel diameter, number of particles, and specific surface area of the mediu...
متن کاملBiofilter media mixture ratio of wood chips and compost treating swine odors.
Biofilter media mixtures were compared in 18 pilot-scale biofilters treating pit gases from a swine facility. The compost and wood chips mixtures ranged from 100% wood chips to a 50-50 blend in 10% increments. The effect of three media moisture contents (low, medium, and high) on biofilter performance was also evaluated. Odor and hydrogen sulfide reduction did not change significantly for mixtu...
