The rapid increase of the potent greenhouse gas methane in the atmosphere creates great
urgency to develop and deploy technologies for methane mitigation. One approach to …

Mass transfer and kinetic limitations are two obstacles to the removal of a pollutant from the
gas phase in a biofilter (BF) or a biotrickling filter (BTF). The issue becomes more …

The on-going annual increase in global methane (CH 4) emissions can be largely attributed
to anthropogenic activities. However, as more than half of these emissions are diffuse and …

In Canada, the piggery industry is an essential part of the agricultural sector, but the
anaerobic storage conditions of swine slurry lead to the emission of methane (CH4), an …

The use of biofilters (working bed volume of 7.85 L) for the oxidation of CH 4 at low
concentrations (from 0.17% v/v to 3.63% v/v, typically in waste gas from anaerobic sewage …

Sewage from residents and industries is collected and transported to wastewater treatment
plants (WWTPs) with sewer networks. The operation of WWTPs results in emissions of …

The effect of non-ionic surfactants on the biofiltration of methane (CH4) was analyzed. Two
biofilters (BF) treating CH4 were operated for one year at fixed CH4 concentration of 4.8 …

Using hybrid packing materials in biofiltration systems takes advantage of both the inorganic
and organic properties offered by the medium including structural stability and a source of …
