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 ...
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 ...
Two‐stage gas‐phase bioreactor for the combined removal of hydrogen sulphide, methanol and α‐pinene
(Taylor & Francis, 2009)
Biological treatment systems have emerged as cost‐effective and eco‐friendly techniques for treating waste gases from process industries at moderately high gas flow rates and low pollutant concentrations. In this study, ...
Optimization of the treatment of carbon monoxide-polluted air in biofilters
(Elsevier, 2009-01)
This work is the first extensive study on the removal of carbon monoxide from polluted air in biofilters. It compares the performance of two packing materials, namely lava rock alone and a mixture of peat and lava rock. ...
Removal of dichloromethane from waste gases in one- and two-liquid-phase stirred tank bioreactors and biotrickling filters
(Elsevier, 2009-01)
The removal of dichloromethane (DCM) from polluted air was studied both in biotrickling filters and in continuous stirred tank bioreactors, using either a single-liquid aqueous phase or a combination of an aqueous–organic ...
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 ...
Experimental and neural model analysis of styrene removal from polluted air in a biofilter
(Wiley-Blackwell, 2009-07)
BACKGROUND: Biofilters are efficient systems for treating malodorous emissions. The mechanism involved during pollutant transfer and subsequent biotransformation within a biofilm is a complex process. The use of artificial ...
