Development of a family of large-scale biothechnological processes to desukphurise industrial gases
(Universidade da Coruña, 2007)[Abstract] In this paper an overview is given of a new biotechnological process to remove hydrogen sulphide from gas streams. This process is jointly developed by Wageningen University, Delft University of Technology, ... -
Development of a novel bioscrubbing process for complete treatment of NOx from flue gases
(Universidade da Coruña, 2007)[Abstract] In this study, a novel bioscrubber was developed for the complete treatment of NOx from flue gases. As a first step, an autotrophic ANNAMOX system was developed using ammonia as the electron donor and nitrate ... -
Development of a reliable extraction method for the recovery of total genomic DNA from woodchip colonizing biofilm involved in gas biofiltration
(Universidade da Coruña, 2007)[Abstract] This preliminary study focused on a critical step for the characterization of microbial ecosystem involved in biofiltration. Two aspects of nucleic acid recovery were explored: (i) cell dispersion (three methods ... -
Dichloromethane removal using mixed cultures in a biofilter and a modified rotating biological contactor -start up studies
(Universidade da Coruña, 2007)[Abstract] Dichloromethane (DCM) is a widely used organic solvent which is considered to be hazardous air pollutant. Regulatory standards in many countries require its removal from waste gas streams. Biological waste gas ... -
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 ... -
FT-IR characterization of biofilms formed on engineered biofiltration media treating volatile organic emissions for the forest products industry
(Universidade da Coruña, 2007)[Abstract] The gaseous emissions from hardboard mill presses at lumber plants contain both volatile and condensable organic compounds, as well as fine wood and other very small particulate material. Biological emissions ... -
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 ... -
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 ... -
High H2S concentrations abatement in a biotrickling filter: start-up at controlled pH and effect of the EBRT and O2H2S supply ratio
(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 ... -
High throughput biofiltration for odour control at water purification plant
(Universidade da Coruña, 2007)[Abstract] A high throughput trickling biofilter for odour control was designed basing on the principles of biotrickling filter technology developed in Moscow Bakh Institute of Biochemistry. All the necessary blocks except ... -
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 ... -
