Treatment of gas-phase methanol in conventional biofilters packed with lava rock
(Elsevier, 2005-06)
The performance of laboratory scale methanol-degrading biofilters packed with lava rock was checked during almost 1 yr under different conditions. The biomass concentration and biomass adaptation of the inoculum dramatically ...
Effect of key parameters on the removal of formaldehyde and methanol in gas-phase biotrickling filters
(Elsevier, 2006-12)
The effect of some important operation parameters, as pH, pollutant load and composition of the nutrient media, on the biodegradation of a mixture of formaldehyde and methanol in a gas-phase biotrickling filter was studied. ...
Steady- and transient-state operation of a two-stage bioreactor for the treatment of a gaseous mixture of hydrogen sulphide, methanol and α-pinene
(Wiley-Blackwell, 2010-03)
A two-stage bioreactor, comprising a biotrickling filter (BTF) as the first stage and a biofilter (BF) as the second stage, operated under steady- and transient-state conditions, was tested to remove gas-phase hydrogen ...
Optimization of nutrient supply in a downflow gas-phase biofilter packed with an inert carrier
(Springer, 2002-01)
Several methodologies were tested to supply nutrients to a downflow biofilter packed with perlite and used to treat toluene-polluted air. Despite the presence of an inorganic carrier, elimination capacities of up to around ...
A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters
(MDPI, 2011-08)
After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ...
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, ...
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. ...
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 ...
Parameters affecting performance and modeling of biofilters treating alkylbenzene-polluted air
(Springer, 2001-03)
Both short-term and long-term biofiltration experiments were undertaken with a biofilter inoculated with a defined microbial consortium and treating an alkylbenzene mixture. The results obtained with such a biofilter in ...
