Artificial neural network based model for evaluating performance of immobilized cell biofilter
(Universidade da Coruña, 2007)[Abstract] Artificial neural networks (ANNs) are powerful data driven modelling tools which has the potential to approximate and interpret complex input/output relationships based on the given sets of data matrix. In this ... -
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, ... -
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 ... -
Modeling of fungal biofilter for the abatement of hydropic VOCs
(Universidade da Coruña, 2007)[Abstract] This work describes the growth of filamentous fungi in biofilters for the degradation of hydrophobic VOCs. The study system was n-hexane and the fungus Fusarium solani B1. The system is mathematically described ... -
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 ... -
Performance of peat biofilters treating ethyl acetate and toluene mixtures under non-steady-state conditions
(Universidade da Coruña, 2007)[Abstract] This paper presents the response of peat biofilters to loading changes corresponding to industrial practices such as overnight and weekend shutdowns, intermittent emission or inlet concentration peaks. Three ... -
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 ... -
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 ... -
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 ... -
Menbrane inlet mass spectrometry (MIMS) as a tool for evaluating biological air filters in agriculture
(Universidade da Coruña, 2007)[Abstract] Membrane inlet mass spectrometry (MIMS) is presented as a new tool for monitoring the removal efficiency of biofilters with respect to odour compounds. The MIMS technique is based on the separation of volatile ... -
Removal of odour and ammnia in ventilation air from growing-finishing pig units using vertical biofilters
(Universidade da Coruña, 2007)[Abstract] The aim of this study was to investigate the removal of odour and ammonia from outlet air using vertical biofilters in two units with growing-finishing pigs in the winter. Woodchips were used as media in the ... -
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 ... -
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, ... -
Study of a desulfurization process to convert dibenzothiophene to 2-hydroxybiphenyl by Rhodococcus rhodochrous NRRL (B-2149)
(Universidade da Coruña, 2007)[Abstract] Actually, a great effort is being given to research on biodesulfurization processes, i.e., processes in which sulfur can be removed selectively from sulfur-compound moities without altering its British thermal ... -
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 ... -
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 ... -
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 ... -
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 ... -
Co-treatment of benzene and toluene vapours in a biofilter: A factorial design approach
