Biologische Reinigung organisch verschmutzter Abluftströme

Biological Exhaust Air Cleaning. Production and refining of oils and fats from vegetable and animal raw materials generate –sometimes to a serious extent – organically polluted exhaust gases. Relatively new compared to conventional physico-chemical methods for air purification is the conversion of undesired impurities with the help of microorganisms within the scope of Biological Exhaust Air Cleaning. Depending on the objectives one of the systems biofilter. bioscrubber or biological trickling bed reactor can be chosen. This paper describes the present state of technology and the latest developments in the field of biological air refining and elucidates working principle and potential applications of the systems mentioned above. A procedure is presented aiming at a systematic election of an optimal air refining process.
