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 ...
Formaldehyde biodegradation and its inhibitory effect on nitrification
(Wiley-Blackwell, 2004-05)
The simultaneous removal of formaldehyde and ammonium in aerobic cultures and the inhibitory effect of formaldehyde on ammonium oxidation were investigated. The influence of a co-substrate, methanol, on formaldehyde ...
Optimization of the landfill leachate treatment by the Fenton process
(Wiley-Blackwell, 2013-03)
The Fenton process was used with the objective of improving the biodegradability of the leachate pretreated biologically up to a value compatible with a subsequent biological treatment. The optimum reaction and settlement ...
Biofiltration of waste gases in a reactor with a split-feed
(Wiley-Blackwell, 2003-06)
The efficiency of using different feed strategies was evaluated in the case of a gas-phase biofilter packed with an inert carrier material. During a preliminary control-period, the biofilter was first fed with a single ...
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, ...
Performance of a fungal monolith bioreactor for the removal of styrene from polluted air
(Elsevier, 2010-04)
Gas-phase styrene removal using the fungus, Sporothrix variecibatus was evaluated in a
novel monolith bioreactor, receiving a continuous supply of nutrients from the trickling
liquid phase. During the start-up process, ...
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 ...
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 ...
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 ...
