Co-treatment of benzene and toluene vapours in a biofilter: A factorial design approach
(Universidade da Coruña, 2007)[Abstract] Biofiltration has now become an indispensable treatment technique for the removal of low concentrations of Volatile Organic Compounds (VOCs) from process vent streams. This study involves performance evaluation ... -
Comparison of three pilot plants filled with organic materials for the treatment of air pollutants from a composting plant
(Universidade da Coruña, 2007)[Abstract] This study has compared the efficiency of 3 mixes of organic materials [peat + coco fibre; branches (1 vol) + wood (1vol) + peat (1 vol.); + branches (5 vol) + wood (2vol) + peat (1 vol.)] used in biofiltres ... -
Continuous monitoring of odours at a biofilter outlet
(Universidade da Coruña, 2007)[Abstract] The experience matured in the field of biofiltration applied to odour removal enabled to study the correlation between some of the characteristic parameters of the biofilter bed (e.g. T, RH, ?P) with the emitted ... -
Control of methane emissions issuing from lanffills: the Canadian case
(Universidade da Coruña, 2007)[Abstract] During their storage in landfills, wastes are biodegraded, which results in the production of biogas and leachate. Over recent years, the handling of the leachate product has become one of major concern. However, ... -
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 ... -
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 ... -
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
