The effects of successive mixing (homogenization) packing material (peat), with or without water addition, on the removal toluene vapors in a biofilter were studied. Over period 50 days, an increase Elimination Capacity (EC) approximately 240% was obtained by and additions. After each mixing, high EC maintained only for short 3–4 days. this time, decreased performance observed, probably associated development dried and/or clogged zones. In long-term experiments, attenuation recovery observed...
The moisture content of biofilter media is a key parameter for its adequate performance. Control requires better understanding the drying support due to changes in inlet air temperature and relative humidity from metabolic heat production by pollutant oxidation. A dynamic one-dimensional model was developed describe effect on Mass energy balances were established an elementary representative volume. biological reaction term incorporated temperature, water content, concentration effects....
The widespread use of methyl tert ‐butyl ether (MTBE) as a gasoline additive has resulted in large number cases groundwater contamination. Bioremediation is often proposed the most promising alternative after treatment. However, MTBE biodegradation appears to be quite different from usual contaminants such benzene, toluene, ethyl benzene and xylene (BTEX). In present paper, characteristics consortium degrading liquid cultures are presented discussed. degradation rate was fast followed zero...
WOx/TiO2 catalysts were synthesized by impregnating aqueous (NH4)2WO4 on hydrous titania nanotubes. The materials annealed in air at 500 °C and characterized X-ray diffraction (XRD), Raman spectroscopy, high-resolution transmission electron microscopy (HRTEM), high-angle annular dark-field scanning (HAADF-STEM), photoelectron spectroscopy (XPS); their catalytic activity was evaluated the oxidation reaction of dibenzothiophene (DBT). After annealing °C, structure support transformed from...
A population of Desertifilum (Cyanobacteria, Oscillatoriales) from an oligotrophic desertic biotope was isolated and characterized using a polyphasic approach including molecular, morphological, ecological information. The initially assumed to be new species based on biogeographic separation other existing species, however, phylogenetic analyses sequences the 16S rRNA gene 16S–23S ITS region, placed this strain clearly within type tharense . Comparative analysis morphology, similarity,...
Biotechnological techniques, including biofilters and biotrickling filters are increasingly used to treat air polluted with VOCs (Volatile Organic Compounds). In this work, the start-up, effect of gaseous ammonia addition on toluene removal rate, problems heat accumulation performance a laboratory scale biofilter were studied. The packing material was sterilized peat enriched mineral medium inoculated an adapted consortium (two yeast five bacteria). Start-up showed short adaptation period...
Abstract The measurement of pressure drop(Δ P ) across an aerated fermentation bed is proposed as alternative on‐line sensor for the qualitative and, in some cases, quantitative, macroscopic changes a static solid state fermentor. An increase Δ correlated with evolution different phases Aspergillus niger growth: germination, vegetative growth, limitation, and sporulation, we observed microscope. For case where support not modified during water content remains constant, i.e., synthetic resin...
