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 ...
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 ...
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 ...
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 ...
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 ...
FT-IR characterization of biofilms formed on engineered biofiltration media treating volatile organic emissions for the forest products industry
(Universidade da Coruña, 2007)
[Abstract] The gaseous emissions from hardboard mill presses at lumber plants contain both volatile and condensable organic compounds, as well as fine wood and other very small particulate material. Biological emissions ...
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 ...
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 ...
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 ...
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 ...
