Formaldehyde biodegradation in the presence of methanol under denitrifying conditions
(Wiley-Blackwell, 2006)
Simultaneous formaldehyde and methanol biodegradation and also denitrification were studied in batch assays and in a continuous laboratory-scale reactor. In batch assays, high formaldehyde concentrations (up to 1360 mg ...
Combined post-ozonation and biological treatment of recalcitrant wastewater from a resin-producing factory
(Elsevier, 2007-05)
In this study, effluent from the biological treatment of wastewater from a resin-producing factory containing recalcitrant compounds was ozonated under different conditions. Afterwards, the biodegradability of the ozonated ...
Performance of a biofilter for the removal of high concentrations of styrene under steady and non-steady state conditions
(Elsevier, 2009-08-30)
The performance of a laboratory scale perlite biofilter inoculated with a mixed culture was evaluated for gas phase styrene removal under various operating conditions. Experiments were carried out by subjecting the biofilter ...
Treatment of gas-phase methanol in conventional biofilters packed with lava rock
(Elsevier, 2005-06)
The performance of laboratory scale methanol-degrading biofilters packed with lava rock was checked during almost 1 yr under different conditions. The biomass concentration and biomass adaptation of the inoculum dramatically ...
Formaldehyde biodegradation and its effect on the denitrification process
(Taylor & Francis, 2007)
Simultaneous formaldehyde biodegradation and denitrification in batch assays and in a continuous lab-scale reactor were studied. In batch assays, initial biodegradation rates between 0.7 and 3.3 g CH2O g VSS-1 d-1 were ...
Effect of key parameters on the removal of formaldehyde and methanol in gas-phase biotrickling filters
(Elsevier, 2006-12)
The effect of some important operation parameters, as pH, pollutant load and composition of the nutrient media, on the biodegradation of a mixture of formaldehyde and methanol in a gas-phase biotrickling filter was studied. ...
Energía y sostenibilidad : incidencia en el medio marino
(Netbiblo, 2003)
[Resumen] En un momento en el que la preocupacion mundial por la sostenibilidad del planeta esta presente ya de forma permanente en todos los foros, es importante reflexionar sobre cuales son las ideas fundamentales en las ...
Formaldehyde and urea removal in a denitrifying granular sludge blanket reactor
(Elsevier, 2004-09)
Simultaneous formaldehyde biodegradation, urea hydrolysis and denitrification in anoxic batch assays and in a continuous laboratory anoxic reactor were investigated. In batch assays, the initial formaldehyde biodegradation ...
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 ...
