In a biofilter, the waste gas is blown through a reactor which is filled with an organic carrier material, as e.g. wood root, bark or mixtures. During the start-up of the biofilter, the presence of pollutants in the waste gas will result in a shift from the natural microbial flora on the carrier material towards a predominance of the most suited groups of microorganisms that efficiently metabolise the target pollutants. Only in exceptional cases, inoculation with selected microorganisms is needed in order to minimize the start-up period. Crucial with regard to the biofilter is the correct dimensioning of the reactor in correspondence to the air flow/pollutant load and the correct preconditioning of the incoming air. Regarding the latter, a nearly 100% humidification of the incoming air is crucial.
