Biodegradation of styrene laden waste gas stream using a compost-based biofilter.
Biological treatment of waste gas styrene vapor was investigated in a three-stage bench-scale biofilter. Yard waste compost mixed with shredded hard plastics in a 25:75 v/v ratio of plastics:compost was inoculated with thickened municipal activated sludge. Microbial acclimation to styrene was achieved by exposing the system to an inlet concentration (C(In)) of 0.25 gm(-3) styrene and an empty b...
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 کاملTreatment of styrene- laden waste gas stream using compost-based biofilter
Biofiltration of air containing styrene vapor was investigated using a three-stage bench scale biofilter. The biofilter was packed with yard waste compost using hard plastics as a bulking agent in a 75:25 v/v mix of plastics: compost. The feed concentration was made by bubbling air through a styrene stock solution. The system was inoculated with thickened activated sludge and the effects of loa...
متن کاملBiodegradation of toluene in a membrane biofilter
A membrane biofilter is used to biodegrade toluene in the gas phase. Active microorganisms are immobilized on the outside of a hollow fiber membrane cartridge and air containing toluene as the contaminant is passed through the membrane fibers. A porous polysulfone membrane containing water in the pore is used through which both toluene and oxygen are diffused to the biofilm attached to the outs...
متن کاملMeasurement of biosolids compost odor emissions from a windrow, static pile, and biofilter.
A pilot study was conducted to compare odor emissions from a windrow process and an aerated static pile and to determine the odor reduction efficiency of a pilot two-phase biofilter for odor control of biosolids composting. Chemical compounds identified as responsible for odors from biosolids composting include ammonia, dimethyl disulfide, carbon disulfide, formic acid, acetic acid, and sulfur ...
