Hydrodynamics of a Laboratory Scale Rotating Biological Contactor and its Application for Decolorization of Textle Dyes by White Rot Fungus Irpex Lacteus

Popis výsledku v původním jazyce

Residence time distributions of the liquid phase in the rotating biological contactor were measured to obtain hydrodynamic characteristics. The measurements were carried out at various liquid volumetric flow rates and at different rotational speeds of the discs uncovered with the biomass. The measured data were used to determine the liquid mean residence time and parameters of the gamma distribution model and of the model of the stirred tanks in series with the back-flow. The residence time distributions were also measured after 36 days of the reactor operation, i.e., with the discs covered with the Irpex lacteus mycelium biofilm. The flow behavior of the reactor without the fungus was close to the ideally stirred reactor behavior. The presence of thebiomass in the reactor brought about deviations from the ideal mixing. Continuous decolorization experiments with the textile dye Remazol Brilliant Blue R and with a sample of industrial textile waste water were performed.
