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 ...
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 ...
