Abstract
The biomass accumulation effect on the performance of a biotrickling filter (BTF) has been assessed in termps of the hydrodynamics and the void space available to gas treatment changes. It was determined tht the available space for gas treatment inside the BTF had been reduced to almost half of that calculated initially when packing was biofilm free. Assuming that flow of liquid through a BTF can be described by the dispersion plug flow model, dispersion coefficients (Ddisp) of 0,12 and 0,33 m2 ...
The biomass accumulation effect on the performance of a biotrickling filter (BTF) has been assessed in termps of the hydrodynamics and the void space available to gas treatment changes. It was determined tht the available space for gas treatment inside the BTF had been reduced to almost half of that calculated initially when packing was biofilm free. Assuming that flow of liquid through a BTF can be described by the dispersion plug flow model, dispersion coefficients (Ddisp) of 0,12 and 0,33 m2 h-1 were determined when BTF was packed with clean and colonized packing respectively. These coefficients and other parameters assessed experimentally were used in a mathematical model to describe the dimethyl disulfide (DMDS) odors removal along the BTF height. The model that considered dispersion for the liquid flow fitted better to the experimental data, suggesting the importance of the axial dispersion which should be considered when modelling.
