A comparative study of the characteristics and physical behaviour of different packing materials commonly used in biofiltration
(Universidade da Coruña, 2007)
Conference report
Open AccessIn 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 and inorganic ... -
Aerobic desulfurization of biogas by acidic biotrickling filtration in a randomly packed reactor
(2014-09-15)
Article
Restricted access - publisher's policyBiotrickling filters for biogas desulfurization still must prove their stability and robustness in the long run under extreme conditions. Long-term desulfurization of high loads of H2S under acidic pH was studied in a ... -
Biological sweetening of energy gases mimics in biotrickling filters
(2008-03)
Article
Restricted access - publisher's policyRemoval of hydrogen sulfide from waste and energy-rich gases is required, not only because of environmental health and safety reasons, but also because of operational reasons if such gases have to be used for energy ... -

Biomass accumulation in a biofilter treating toluene at high loads – Part 2: Model development, calibration and validation
(Elsevier, 2012-10-15)
Article
Open AccessIn this work, a dynamic model describing volatile organic compounds abatement and the corresponding biomass accumulation is developed, calibrated and validated. The mathematical model is based on detailed mass balances ... -
Characterization of organic packing materials in the removal of ammonia gas in automated biofilters
(Consejo Superior de Investigaciones Científicas (CSIC), 2005)
Conference report
Open AccessA fully-automated pilot-scale biofilter filled with coconut fiber as packing material was investigatedfor treatment of ammonia-containing off-gas streams. Coconut fiber was completely characterized ... -
A comparative study based on physical characteristics of suitable packing materials in biofiltration
(2010-02-02)
Article
Open AccessIn the present work, 10 packing materials commonly used as support media in biofiltration are analysed and compared to evaluate their suitability according to physical characteristics. The nature of the packing material ... -
Comparison of organic packing materials for toluene biofiltration
(Universidade da Coruña, 2005)
Conference report
Open Accesshe paper focuses on the operation of a pilot plant with four biofilters operated in parallel for determining the suitability of coconut fiber, peat, compost from the digested sludge of a wastewater treatment plant and pine ... -
DEPUR: a knowledge-based tool for wastewater treatment plants
(1993-11)
Research report
Open AccessA malfunction of a wastewater treatment plant is a big social and biological problem. A poorly treated waste water outside the plant could provoke dangerous consequences for human beings as well as the nature itself. The ... -
Development of a kinetic model for elemental sulfur and sulfate formation from the autotrophic sulfide oxidation using respirometric techniques
(2009-04-01)
Article
Open AccessA kinetic model for the elemental sulfur and sulfate production from the autotrophic sulfide oxidation has been proposed. It is based on two kinetic equations able to describe the simultaneous microbial consumption of ... -
Dynamic modelling of ammonia biofiltration from waste gases
(Consejo Superior de Investigaciones Científicas (CSIC), 2005)
Conference report
Open AccessA dynamic model to describe ammonia removal in a gas-phase biofilter was developed. The math-ematical model is based on discretized mass balances and detailed nitrification kinetics that includeinhibitory ... -
Evaluation of mass transfer coefficients in biotrickling filters: experimental determination and comparison to correlations
(2009-09)
Article
Open AccessOverall mass transfer coefficients (KGa and KLa) were determined experimentally for four different-nature packing materials used in gas-phase biotrickling filters. A simple methodology based on overall mass balances and ... -

(Universidade da Coruña, 2007)
Conference report
Open AccessIn this study, a biotrickling filter reactor was set up and used to treat high concentrations of gaseousH2S. Inoculation was carried out at an inlet H2S concentration of 1,000 ppmv (27.8 g H2S m-3 h-1)and sludge from a ... -
Interaction between sorption and biodegradation in a biofilter packed with activated carbon
(2012)
Article
Open AccessThe main objective of this study is to evaluate qualitatively and quantitatively the effect of starvation periods in the biodegradation capacity of microorganisms when the support media is a material with high sorption ... -
