The elimination capacity (EC) is defined as the ratio of gas flow rate (Qg) to the bed volume (V), multiplied by the difference between the pollutant concentration in the influent and the effluent waste gases (Cgo — Cgo), it indicates a measure of the biofilter ability in removing the pollutants. From this definition it is evident that, because removal efficiency is expected to be close to 100%, the elimination capacity also ranges between 10 and 160 g m—3 h—1 (1). In addition, this parameter also is higher close to the inlet side, as happens for mass loading. The elimination capacity increases with mass loading and inlet pollutant concen tration and decreases with residence time, the limiting value depending not only on the pollutant degradability, but also on the support material and the operating conditions. Beyond this value it is nearly constant (20).
