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. ...
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 ...
Biofiltration of waste gases containing a mixture of formaldehyde and methanol
(Springer, 2004-04)
Several biofilters and biotrickling filters were used for the treatment of a mixture of formaldehyde and methanol; and their efficiencies were compared. Results obtained with three different inert filter bed materials (lava ...
Hydrodynamic behaviour and comparison of technologies for the removal of excess biomass in gas-phase biofilters
(Elsevier, 2004)
The hydrodynamic behaviour of a biofilter fed toluene and packed with an inert carrier was evaluated on start-up and after long-term operation, using both methane and styrene as tracers in Residence Time Distribution ...
Removal of formaldehyde, methanol, dimethylether and carbon monoxide from waste gases of synthetic resin-producing industries
(Elsevier, 2008-02)
The removal of mixtures of gas-phase pollutants released from formaldehyde- and formaldehyde resin-producing industries was studied in different bioreactor systems. The waste gases contained formaldehyde, methanol, ...
