ABSTRACT
The use of biofilters for air treatment is a common method since decades. Science has the duty to examine existing technologies and find new concepts. This has to be done with regard to the roots and basics of biofiltration and to actual and future demands. Hence, research and development firstly have to conduct performance analysis under laboratory and large-scale conditions with special regard to the use of surrogate parameters suitable or at least promising concerning process control as well to real load parameters. In addition, science has to explain the phenomena observerd, resulting in a better process understanding and, if possible, modelling of processes. Derived from that, predictions for possible future applications are needed as a guideline for the commercial biofilter market development. This paper shows different approaches to fulfil these demands. Results from large-scale applications as well as laboratory scale applications will be shown.
