Combined biological and physicochemical waste-gas cleaning techniques
(Taylor & Francis, 2012-06)
This review presents a general overview of physical, chemical and biological waste-gas treatment techniques such as adsorption, absorption, oxidation and biodegradation, focusing more extensively on combined processes. It ...
Steady- and transient-state operation of a two-stage bioreactor for the treatment of a gaseous mixture of hydrogen sulphide, methanol and α-pinene
(Wiley-Blackwell, 2010-03)
A two-stage bioreactor, comprising a biotrickling filter (BTF) as the first stage and a biofilter (BF) as the second stage, operated under steady- and transient-state conditions, was tested to remove gas-phase hydrogen ...
Bioplastic production using wood mill effluents as feedstock
(IWA Publishing, 2011)
[Abstract] Fibreboard production is one of the most important industrial activities in Galicia (Spain). Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final ...
Valuable product production from wood mill effluents
(IWA Publishing, 2010)
Fibreboard production is one of the most important industrial activities in Galicia (Spain). Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final product and ...
Biofiltration of mixtures of gas-phase styrene and acetone with the fungus Sporothrix variecibatus
(Elsevier, 2010-12)
The biodegradation performance of a biofilter, inoculated with the fungus Sporothrix variecibatus, to treat gas-phase styrene and acetone mixtures under steady-state and transient conditions was evaluated. Experiments were ...
Use of Styrene as Sole Carbon Source by the Fungus Exophiala oligosperma: Optimization and Modeling of Biodegradation, Pathway Elucidation, and Cell Membrane Composition
(Springer, 2012-11)
Biodegradation of styrene by Exophiala sp. was tested at different initial concentrations (19.3–170.6 mg l−1), pH (2.8–8.7), and temperatures (19.8–45.1 °C), for 120 h according to a 23 full-factorial central composite ...
Effect of oil concentration and residence time on the biodegradation of α-pinene vapours in two-liquid phase suspended-growth bioreactors
(Elsevier, 2012-02-20)
Recently, research on the use of binary aqueous–organic liquid phase systems for the treatment of polluted air has significantly increased. This paper reports the removal of α-pinene from a waste air stream in a continuous ...
Biodegradation of BTEX in a fungal biofilter: Influence of operational parameters, effect of shock-loads and substrate stratification
(Elsevier, 2012-07)
The effect of relative humidity (RH: 30% to >95%) of a gas-phase mixture composed of benzene, toluene, ethylbenzene and para-, meta- and ortho-xylenes (BTEX), inlet concentrations (0.2–12.6 g m−3), and empty bed residence ...
Evaluation of the biomethane potential of solid fish waste
(Elsevier, 2012-07)
Manufacturing processes in fish canning industries generate a considerable amount of solid waste that can be digested anaerobically. The aim of this research was to study the biochemical methane potential of different solid ...
A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters
(MDPI, 2011-08)
After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ...
