Mathematical modeling of wastewater decolorization in a trickle-bed bioreactor
Original language description
This work focuses on mathematical modeling of removal of organic dyes from textile industry waste waters by a white-rot fungus Irpex lacteus in a trickle-bed bioreactor. We developed a mathematical model of biomass and decolorization process dynamics. The model comprises mass balances of glucose and the dye in a fungal biofilm and a liquid film. The biofilm is modeled using a spatially two-dimensional domain. The liquid film is considered as homogeneous in the direction normal to the biofilm surface. The biomass growth, decay and the erosion of the biofilm are taken into account. Using experimental data, we identified values of key model parameters: the dye degradation rate constant, biofilm corrugation factor and liquid velocity. Considering the dye degradation rate constant 1 x 10(-5) kg m(-3) s(-1), we found optimal values of the corrugation factor 0.853 and 0.59 and values of the liquid velocity 5.23 x 10(-3) m s(-1) and 6.2 x 10(-3) m s(-1) at initial dye concentrations 0.09433 kg
