Combined post-ozonation and biological treatment of recalcitrant wastewater from a resin-producing factory
(Elsevier, 2007-05)
In this study, effluent from the biological treatment of wastewater from a resin-producing factory containing recalcitrant compounds was ozonated under different conditions. Afterwards, the biodegradability of the ozonated ...
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 ...
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 ...
Mesophilic and thermophilic biotreatment of BTEX-polluted air in reactors
(Wiley-Blackwell, 2007-08)
This study compares the removal of a mixture of benzene, toluene, ethylbenzene, and all three xylene isomers (BTEX) in mesophilic and thermophilic (50°C) bioreactors. In the mesophilic reactor fungi became dominant after ...
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 ...
