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 ...
Removal of ammonia by immobilizaed Nitrosomonas europaea in a biotrickling filter packed with polyurethane foam
(Universidade da Coruña, 2007)
[Abstract] A chemolithoautrotrophic microorganism Nitrosomonas europaea has been utilized to remove gaseous ammonia in a biotrickling filter packed with polyurethane foam. The optimal pH for removing was 7.5 and the ...
An innovative biotrickling filter for H2S removal from biogas
(Universidade da Coruña, 2007)
[Abstract] A novel biotrickling filter system was developed to remove H2S from biogas. The aim was to remove 2000 ppmv of H2S to less than 3 ppmv in order to use biogas in combination with fuel cells, as vehicle fuel or ...
Removal of dimethyl sulfide in a thermophilic membrane bioreactor
(Universidade da Coruña, 2007)
[Abstract] In this study, the removal of dimethylsulfide was investigated in a flat composite membrane bioreactor (MBR) at elevated temperature (52°C). A composite membrane with a 2 µm polydimethylsiloxane (PDMS) coating ...
Modeling of biomass accumulation and filter bed st6ructure change in biofilters for gaseous toluene removal
(Universidade da Coruña, 2007)
[Abstract] In this study, a proper microbial growth model was established and analyzed to investigate the biomass accumulation process in biofilters. Four biofilters treating gaseous toluene were set up in parallel and ...
Removal od hydrogen sulfide using upflow and downflow biofilters
(Universidade da Coruña, 2007)
[Abstract] The objective of this study was to determine the efficiency of different types of biofilters for hydrogen sulfide removal. The study consisted of two parts. The first part compared the hydrogen sulfide removal ...
Modelling the absorption of styrene and acetone on activated carbon and perlite beds
(Universidade da Coruña, 2007)
[Abstract] Experimental data from the Institute of Chemical Technology, Prague were analysed to derive some simple models of the rate of adsorption of either styrene or acetone from dilute air mixtures on sterile beds of ...
Removal of a mixture of oxygenated VOCs in a biotrickling filter
(Universidade da Coruña, 2007)
[Abstract] Laboratory scale-studies on the biodegradation of a 1:1:1 wt mixture of three oxygenated volatile organic compounds (VOCs), ethanol, ethyl acetate and methyl-ethyl ketone (MEK) in a biotrickling filter were ...
