Mathematical model of decolourization in a rotating disc reactor

Popis výsledku v původním jazyce

This work presents a mathematical model of the biodegradation of an organic dye in a rotating disc reactor operated in a batch mode with discs coated with a mycelium of a white-rot fungus. The two-dimensional model domain represents the surface of one half of a disc. The disc is considered to be covered with two layers (biofilm, liquid film) and is partially immersed in bulk liquid. The biofilm is assumed to maintain a constant thickness in time over the entire domain. The enzyme laccase is presumed toplay the main role in the decolourization. The regular disc rotation is described using the radial coordinate with the immersion process simulated by a step-like function of the angular coordinate. Using experimental data, we identified values of principal model parameters. Considering the Michaelis-Menten constant value of 0.005 kg mMINUS SIGN 3, we found suboptimal values of the reaction rate constant (0.003 mol mMINUS SIGN 3 sMINUS SIGN 1), proportionality constant influencing the thi
