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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Long-term stability of Pseudomonas putida cultures suring the off-gas treatment of toluene
(Universidade da Coruña, 2007)[Abstract] The long term stability of Pseudomonas putida mt-2 and Pseudomonas putida F1, bacteria harbouring the genes responsible for toluene biodegradation in the plasmid pWW0 and in the chromosome, respectively, was ... -
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 ... -
Microbial solvent regeneration in biotreatment of air contaminated by styrene
(Universidade da Coruña, 2007)[Abstract] In this study, the biodegradation of a styrene-polluted waste gas in a reactor containing 5 L of a biphasic mixture (10:90% v/v) of organic solvent (silicone oil) – water – biomass was investigated to establish ... -
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 ... -
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 ... -
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 ... -
Refurbishment of an odour collection and biofilter treatment system at a municipal solid waste composting facility in Perth, Western Australia
(Universidade da Coruña, 2007)[Abstract] This paper discusses a case study at a large, regional Municipal Solid Waste composting plant in Perth, Western Australia, where odour emissions from the facility have resulted in adverse odour impacts in the ... -
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 ...
