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, ... -
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 ... -
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 ... -
Modeling of biomass accumulation and filter bed st6ructure change in biofilters for gaseous toluene removal
(Universidade da Coruña, 2007)[Abstract] In this study, a proper microbial growth model was established and analyzed to investigate the biomass accumulation process in biofilters. Four biofilters treating gaseous toluene were set up in parallel and ... -
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 ... -
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 ... -
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 ... -
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 ... -
Performance evaluation of fungal biofilters packed with Pall rings, lava rock, and perlite for a-pinene removal
(Universidade da Coruña, 2007)[Abstract] The most suitable packing material for biofiltration of a-pinene was selected among Pall rings, lava rock, and perlite. In the present study, several biofilters fed a-pinene-polluted air were inoculated with a ... -
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 ... -
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 ... -
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 ... -
