(Universidade da Coruña, 2007)[Abstract] In this study, a biotrickling filter reactor was set up and used to treat high concentrations of gaseous H2S. Inoculation was carried out at an inlet H2S concentration of 1,000 ppmv (27.8 g H2S m-3 h-1) and ... -
Study of NH3 removal by gas-phase biofiltration: effects of shock loads and watering rate on biofilter performance
(Universidade da Coruña, 2007)[Abstract] Ammonia biofiltration performance under shock loads episodes was studied in a reactor packed with coconut fiber as carrier material. Periodical gas and leachate samplings were analyzed and used to characterize ... -
Degradation of solvent mixture vapors in a biotrickling filter reactor: impact of hydrophilic components loading and loading release dynamic
(Universidade da Coruña, 2007)[Abstract] Interactions amongst the degradation rates of toluene, xylenes, methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK), n-butyl acetate (n-BA), and acetone (Ac) were investigated in a biotrickling filter ... -
A statistical perspective on biofilter performance in relation to the main process parameters and characteristics of untreated flows
(Universidade da Coruña, 2007)[Abstract] A large number of olfactometric measurements of odour removal efficiency of municipal waste organic fraction and green waste composting installations were compiled and analysed graphically. The number of ... -
Gasoline biofiltration: an analytic model
(Universidade da Coruña, 2007)[Abstract] We present an analytical method of solution for a pair of models representing the removal of gasoline from air by biofiltration. The experimental data showed that the aromatic components of the gasoline were ... -
Characterization of a biotrickling filter treating methanol vapours
(Universidade da Coruña, 2007)[Abstract] 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 ... -
Desulfurisation of biogas by biofiltration
(Universidade da Coruña, 2007)[Abstract] A biofiltration system to eliminate volatile fatty acids (VFAs) and hydrogen sulfide (H2S), using a microbial consortia, was established. The characterization of lava rock, vermiculite and glass rings, as potential ... -
Traetment of the confined air of a spacecraft cabin
(Universidade da Coruña, 2007)[Abstract] A test bench at scale 1/15 has been implemented in order to evaluate the performance of photocatalysis and membrane bioreaction to treat the polluted air of a spacecraft cabin containing 30 mice. Ten pollutants ... -
Effect of various factors to ammonia biodegradation by two stage biofiltration system
(Universidade da Coruña, 2007)[Abstract] An autotrophic ammonia-biodegrading PNNS association was isolated from the biological activated sludge of the fish factory wastewater treatment plant and used in the two-stage biofiltration system with the ammonia ... -
Improving odour management and abatement performance using Olfactory GC-MS
(Universidade da Coruña, 2007)[Abstract] The measurement of odorous emissions is usually assessed either as odour concentrations (OC) by dilution olfactometry or by the chemical analysis of the odorous compounds such as hydrogen sulphide or the separation ... -
Ammonia transformation in a biotrickling air filter
(Universidade da Coruña, 2007)[Abstract] A simple, tubular biotrickling filter was designed for optimal removal of ammonia and odour in ventilation air from a pig house. The removal and transformation of ammonia was studied in detail by analysis and ... -
Gas-phase toluene biodegradation by Burkholderia vietnamiensis G4 in a biofilm membrane reactor
(Universidade da Coruña, 2007)[Abstract] A laboratory-scale biofilm membrane bioreactor inoculated with Burkholderia Vietnamiensis G4 was examined to treat toluene vapors from a synthetic waste gas stream. The gas feed side and nutrient solution were ... -
