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 ...
Co-treatment of hydrogen sulfide and methanol in a single-stage biotrickling filter under acidic conditions
(Elsevier, 2007-06)
Biofiltration of waste gases is cost-effective and environment-friendly compared to the conventional techniques for treating large flow rates of gas streams with low concentrations of pollutants. Pulp and paper industry ...
Effect of phenol on the biological treatment of wastewaters from a resin producing industry
(Elsevier, 2008-06)
The effect of phenol on the biological treatment of wastewaters from a resin producing industry was analyzed in a pre-denitrification system. First, the effect of phenol overloads on the removal of organic matter and ...
Partial Nitrification of Wastewater from an Aminoplastic Resin Producing Factory
(IWA Publishing, 2005)
Nitrification via nitrite was studied in two aerobic reactors treating wastewater from an aminoplastic resin producing factory at HRT varying between 1.37-1.89 and 2.45-3.63 days. Both reactors were fed with concentrations ...
Simultaneous nitrification and formaldehyde biodegradation in an activated sludge unit
(Elsevier Sciencie lted, 2005-11)
The simultaneous removal of formaldehyde and ammonium in a lab-scale activated sludge unit was investigated. The unit was operated at a hydraulic retention time of 2.4 days with an ammonium concentration in the influent ...
Autotrophic deodorization of hydrogen sulfide in a biotrickling filter
(Wiley-Blackwell, 2005-09)
The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter (BTF) packed with plastic Pall rings operating with counter-current flows of the air and liquid streams. Experiments were performed ...
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 ...
Optimization of nutrient supply in a downflow gas-phase biofilter packed with an inert carrier
(Springer, 2002-01)
Several methodologies were tested to supply nutrients to a downflow biofilter packed with perlite and used to treat toluene-polluted air. Despite the presence of an inorganic carrier, elimination capacities of up to around ...
