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 ... -
A statistical perspective on biofilter performance in relation to the main process parameters and characteristics of untreated flows
(Universidade da Coruña, 2007)[Abstract] A large number of olfactometric measurements of odour removal efficiency of municipal waste organic fraction and green waste composting installations were compiled and analysed graphically. The number of ... -
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 ... -
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 ... -
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 ... -
Behaviour and optimization of a novel monolith bioreactor for wasre gas treatment
(Universidade da Coruña, 2007)[Abstract] Treatment of waste gases in bioreactors is cost-effective and environmental-friendly compared to the conventional techniques used for treating large flow rates of gas streams with low concentrations of pollutants. ... -
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 ... -
Biodegradation of methyl ethyl ketone and methyl isopropyl ketone in a composite bead biofilter
(Universidade da Coruña, 2007)[Abstract] Biodegradation of methyl ethyl ketone (MEK) and methyl isopropyl ketone (MIPK) in a composite bead biofilter was investigated. Both microbial growth rate kg and biochemical reaction rate kd would be inhibited ... -
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 ... -
Biofiltration of bitumen vapours - Operational aspects
(Universidade da Coruña, 2007)[Abstract] This study was carried out in response to odour problems around a bitumen mixing and storage plant. The general objective of this study was to determine the potential of biofiltration for the treatment of air ... -
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 ... -
Biological waste gas purification using membranes: opportunities and challenges

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 ... -
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 ... -
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 ...
