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 ...
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 ...
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 ...
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 ...
Biological treatment of industrial wastewater containing formaldehyde and formic acid.
(South African Water Research Comission, 2006-01)
The biological treatment of wastewater from an aminoplastic resin-producing industry was studied in a pre-denitrifica- tion system. This study reports results on the removal of organic matter and nitrogen compounds from ...
Formaldehyde biodegradation and its inhibitory effect on nitrification
(Wiley-Blackwell, 2004-05)
The simultaneous removal of formaldehyde and ammonium in aerobic cultures and the inhibitory effect of formaldehyde on ammonium oxidation were investigated. The influence of a co-substrate, methanol, on formaldehyde ...
Biodegradation and effect of formaldehyde and phenol on the denitrification process
(Elsevier, 2005)
Formaldehyde and phenol biodegradation during the denitrification process was studied at lab-scale, first in anoxic batch assays and then in a continuous anoxic reactor. The biodegradation of formaldehyde (260 mg l−1) as ...
Biofiltration of waste gases containing a mixture of formaldehyde and methanol
(Springer, 2004-04)
Several biofilters and biotrickling filters were used for the treatment of a mixture of formaldehyde and methanol; and their efficiencies were compared. Results obtained with three different inert filter bed materials (lava ...
