Biofiltracja Iotnych zwia̧zków organicznych

A review with 42 refs. covering a modified Monod equation and its use to describe the rate of assimilation of VOCs by microflora. The biofilter operates in the dynamic and in the static regions where process efficiency falls and remains const., resp. The region extent is affected by contaminant concn. and linear gas flow velocity in the biofilter, nature of VOC, type of bed, temp., humidity of gas, bed porosity, etc. After the parameters have been detd. In individual studies (e.g., adsorption, bed hydraulics, lab.-scale deodorization), the process can be modeled. Comparison of simulated with exptl. data showed the model equation to describe well the dynamic and the static steps of the process.
