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 ...
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 ...
Phenol biodegradation and its effect on the nitrification process
(Elsevier, 2005-08)
Phenol biodegradation under aerobic conditions and its effect on the nitrification process were studied, first in batch assays and then in an activated sludge reactor. In batch assays, phenol was completely biodegraded at ...
