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 ... -
Biofilter performance and characterization of a biocatalyst degrading alkylbenzene gases
(2009-06)A biofilter treating alkylbenzene vapors was characterized for its optimal running conditions and kinetic parame-ters. Kinetics of the continuous biofilter were compared to batch kinetic data obtained with biofilm samples ... -
Bioprocesses for air pollution control
(Wiley-Blackwell, 2009)Bioprocesses have been developed as relatively recent alternatives to conventional, non-biological technologies, for waste gas treatment and air pollution control in general. This paper reviews major biodegradation processes ... -
Effect of oil concentration and residence time on the biodegradation of α-pinene vapours in two-liquid phase suspended-growth bioreactors
(Elsevier, 2012-02-20)Recently, research on the use of binary aqueous–organic liquid phase systems for the treatment of polluted air has significantly increased. This paper reports the removal of α-pinene from a waste air stream in a continuous ... -
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 ... -
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 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 ... -
Kinetics of inhibition in the biodegradation of monoaromatic hydrocarbons in presence of heavy metals
(Elsevier Sciencie lted, 2001-06)The toxicity and inhibitory effects of heavy metals such as cadmium, nickel and zinc on alkylbenzene removal were evaluated with a Bacillus strain. The kinetics of alkylbenzene biodegradation with the different heavy metals ... -
Methanogenic and perchloroethylene-dechlorinating activity of anaerobic granular sludge
(Springer, 1998-10)The biodegradation and toxicity of tetrachloroethylene (C2Cl4) and trichloroethylene (C2HCl3) were studied with different anaerobic enrichment cultures using the following electron donors: acetate, propionate, butyrate, ... -
Parameters affecting performance and modeling of biofilters treating alkylbenzene-polluted air
(Springer, 2001-03)Both short-term and long-term biofiltration experiments were undertaken with a biofilter inoculated with a defined microbial consortium and treating an alkylbenzene mixture. The results obtained with such a biofilter in ... -
Two-liquid-phase mesophilic and thermophilic biotrickling filters for the biodegradation of α-pinene
(Elsevier, 2010-12)α-Pinene biodegradation was evaluated in mesophilic and thermophilic biotrickling filters. The potential of silicone oil for enhancing the removal was evaluated too, at both temperatures. Performance was studied at empty ...
