Co-treatment of hydrogen sulfide and methanol in a single-stage biotrickling filter under acidic conditions
(Elsevier, 2007-06)
Biofiltration of waste gases is cost-effective and environment-friendly compared to the conventional techniques for treating large flow rates of gas streams with low concentrations of pollutants. Pulp and paper industry ...
Autotrophic deodorization of hydrogen sulfide in a biotrickling filter
(Wiley-Blackwell, 2005-09)
The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter (BTF) packed with plastic Pall rings operating with counter-current flows of the air and liquid streams. Experiments were performed ...
Removal of methanol from air in a low-pH trickling monolith bioreactor
(Elsevier, 2008-09)
A novel ceramic monolith bioreactor colonized by a methanol-degrading culture was investigated in order to assess its suitability for waste gas treatment. The acidotolerant yeast Candida boidinii was identified as dominant ...
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. ...
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 ...
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 ...
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 ...
Development of a Novel Monolith-Bioreactor for the Treatment of VOC-polluted Air
(Taylor & Francis, 2006)
A novel bioreactor packed with ceramic monolith colonized by a toluene-degrading culture was investigated in order to assess its suitability for waste gas treatment. Operational parameters that were considered included ...
