Proposing a new batch method for assessment of biological activity in H2S degrading biotrickling filters
(Universidade da Coruña, 2007)[Abstract] The proposed batch method consists on measuring the sulfate production rate (SPR) at maximum rate of a set of polyurethane cubes extracted from an ongoing pilot-scale biotrickling filter (BTF) for hydrogen sulfide ... -
Styrene degradation in perlite biofilter: the overall performance characteristics and dynamic response
(Universidade da Coruña, 2007)[Abstract] Styrene’s degradation in a perlite biofilter including the long-term operation, dynamic response to step-changes in inlet concentration and non-use periods were tested. The study was performed in a bench-scale ... -
A comparative study of the characteristics and physical behaviour of different packing materials commonly used in biofiltration
(Universidade da Coruña, 2007)[Abstract] In this study, the characteristics and physical behaviour of 8 different packing materials were compared. The materials were selected according to previous works in the field of biofiltration including organic ... -
Biofiltration systems for the treatment of waste gas from industrial plants
(Universidade da Coruña, 2007)[Abstract] Bord na Móna Environmental Ltd. has gained valuable experience over the years with the installation of over 500 biofilters, primarily in municipal and industrial wastewater treatment plants, food processing and ... -
Suitability of dust and bioaerosols from a pig stable as inoculum for biological air filters
(Universidade da Coruña, 2007)[Abstract] Biofiltration for removing ammonia and odour compounds from ventilation air of pig stables is a promising approach. In order to reduce the time for starting up a well-functioning biofilter a good inoculum suited ... -
Mathematical modeling and simulation of volatile reduced sulfur compounds oxidation in biotrickling filters
(Universidade da Coruña, 2007)[Abstract] The odour generated by industrial gaseous emissions causing nuisances generally is due to the presence of volatile reduced sulfur compounds (VRSC) Although a number of microorganisms are known for degrading VRSC, ... -
Treatmet of gas phase styrene in a biofilter under steady-state conditions
(Universidade da Coruña, 2007)[Abstract] Preliminary studies on the performance of a laboratory scale perlite biofilter inoculated with a mixed culture taken from petrochemical refinery sludge was evaluated for gas phase styrene removal under various ... -
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 ... -
Monitoring and characterization of bacterial populations of two biological air filters during the start up phase
(Universidade da Coruña, 2007)[Abstract] This study aimed to monitor and characterize bacterial populations of two biological air filters during their start up phase (four months). The main objective of this work was to assess the potentiality of a ... -
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 ... -
Characterization and performance evaluation of a two-phase partitioning bioreactor for volatiles organic compounds treatment in off-gas
(Universidade da Coruña, 2007)[Abstract] The treatment of the industrials off-gas strongly evolves with change of the environmental legislation on a worldwide scale. Biotechnics existing for their treatment sometimes present limits for some volatile ... -
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 ... -
Biodegradation of BTXS and substrate interactions on a Bioactive Foam Reactor
(Universidade da Coruña, 2007)[Abstract] A bioactive foam reactor (BFR), using surfactant-driven bubbles and suspended microorganisms, has emerged as a potential alternative to packed-bed biofiltration systems for the treatment of volatile organic ... -
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 ... -
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 ... -
Biofilter response to biomass reactivation for VOC treatment
(Universidade da Coruña, 2007)[Abstract] This research has undertaken a comparative study on using a fresh activated sludge or a refrigerated/ reactivated sludge as active biomass source for biofiltration purposes. A sludge sample was initially selected ... -
Odour and H2S degradation in a full scale biofilter with a mineral based organic coated filter media
(Universidade da Coruña, 2007)[Abstract] In order to minimize the odorous emissions from sludge storage tanks on the waste water treatment plant «Niederrad» of the city of Frankfurt/Main, about 12.000 m3/h of foul air has to be treated. Due to high ... -
