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 ... -
Removal od hydrogen sulfide using upflow and downflow biofilters
(Universidade da Coruña, 2007)[Abstract] The objective of this study was to determine the efficiency of different types of biofilters for hydrogen sulfide removal. The study consisted of two parts. The first part compared the hydrogen sulfide removal ... -
Removal of a mixture of oxygenated VOCs in a biotrickling filter
(Universidade da Coruña, 2007)[Abstract] Laboratory scale-studies on the biodegradation of a 1:1:1 wt mixture of three oxygenated volatile organic compounds (VOCs), ethanol, ethyl acetate and methyl-ethyl ketone (MEK) in a biotrickling filter were ... -
Removal of ammonia by immobilizaed Nitrosomonas europaea in a biotrickling filter packed with polyurethane foam
(Universidade da Coruña, 2007)[Abstract] A chemolithoautrotrophic microorganism Nitrosomonas europaea has been utilized to remove gaseous ammonia in a biotrickling filter packed with polyurethane foam. The optimal pH for removing was 7.5 and the ... -
Removal of dichloromethane from waste gases using a fixed-bed biotrickling filter and a continuous stirred tank bioreactor
(Universidade da Coruña, 2007)[Abstract] A laboratory scale fixed bed biotrickling filter (BTF) and a continuous stirred tank bioreactor (CSTB) have been studied and compared for the elimination of dichloromethane from waste gases. The DCM removal ... -
Removal of dimethyl sulfide in a thermophilic membrane bioreactor
(Universidade da Coruña, 2007)[Abstract] In this study, the removal of dimethylsulfide was investigated in a flat composite membrane bioreactor (MBR) at elevated temperature (52°C). A composite membrane with a 2 µm polydimethylsiloxane (PDMS) coating ... -
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 ... -
Solid-Liquid two-phase partitioning bioreactors for the treatment of gas.-phase VOCs
(Universidade da Coruña, 2007)[Abstract] Two-Phase Partitioning Bioreactors (TPPBs) consist of a cell-containing aqueous phase and a separate, biocompatible and immiscible phase that partitions toxic substrates to the cells based on their metabolic ... -
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 ... -
Study of NH3 removal by gas-phase biofiltration: effects of shock loads and watering rate on biofilter performance
(Universidade da Coruña, 2007)[Abstract] Ammonia biofiltration performance under shock loads episodes was studied in a reactor packed with coconut fiber as carrier material. Periodical gas and leachate samplings were analyzed and used to characterize ... -
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 ... -
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 ... -
