Abstract
The biological waste air purification is state of art and used in many cases. But not all problems in this field are solved and there is a big potential for process optimisations. Longer startup periods are frequent problems of plants using the biochemical capacity of microorganisms. A microbial culture needs a more or less long period for the adaptation to the wastes. The specific inoculation with selected microorganisms is a decisive advantage.
