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 ...
Performance optimization of the fungal biodegradation of α-pinene in gas-phase biofilter
(Elsevier, 2006-08)
A Ophiostoma species using α-pinene as the sole source of carbon and energy converted it into biomass, carbon dioxide and water. The strain was inoculated in a biofilter fed α-pinene polluted air, and it remained the ...
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 ...
Biodegradation of gas-phase styrene using the fungus Sporothrix variecibatus: Impact of pollutant load and transient operation
(Elsevier, 2010-03)
Biofiltration of gas-phase styrene was studied using a newly isolated fungus Sporothrix variecibatus, in a perlite biofilter, at inlet concentrations and gas-flow rates ranging from 0.13 to 14 g m−3 and 0.075 to 0.34 m3 ...
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 ...
Bioprocesses for the removal of nitrogen oxides from polluted air
(Wiley-Blackwell, 2005)
Nitrogen oxides (NOx) of environmental concern are nitrogen monoxide (NO) and nitrogen dioxide (NO2). They are hazardous air pollutants that lead to the formation of acid rain and tropospheric ozone. Both pollutants are ...
Effects of pH, CO2, and flow pattern on the autotrophic degradation of hydrogen sulfide in a biotrickling filter
(Wiley-Blackwell, 2005-11)
In this study, the effects of pH, CO2, and flow pattern on the performance of a biotrickling filter (BTF) packed with plastic Pall rings and treating a H2S-polluted waste gas were investigated to establish the optimum ...
Application of Anaerobic and Ozonation Processes in the Landfill Leachate Treatment
(IWA Publishing, 2006)
The optimization of leachate treatment was investigated as well as the configuration of a biological-ozonation process. The leachate used for the experiments was diluted to 1/5 with tap water and treated anaerobically. The ...
Fungal biofiltration of α-pinene: Effects of temperature, relative humidity, and transient loads
(Wiley-Blackwell, 2007-02)
Over the past decade much effort has been made to develop new carrier materials, more performant biocatalysts, and new types of bioreactors for waste gas treatment. In biofilters fungal biocatalysts are more resistant to ...
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, ...
