Pylnik, I. Dueck] A model for a rotating biological contactor is proposed. The model takes into account the influence of the submergence level and rotational speed of a disk on its capacity. The processing of a substrate is described by the Michaelis-Menten kinetics with allowance for the aerobic nature of the process. Mass transfer between an aqueous medium and a biofilm is taken into account by adding the diffusion resistances of both media. The model includes the consideration of the erosion of the biofilm due to the frictional stress on the surface of the biofilm that moves relative to water. The variability of the thickness of the biofilm along the radius of the disk is taken into account. At the given biokinetic parameters, the depth of the submergence of the disk and its rotational speed that are optimum for the capacity of the biofilter are found using numerical experimentation. Comparison of the results with the experimental data of other authors is performed. Pleiades Publishing, Ltd., 2011 Pylnik S. Tomsk State University, 634050, Tomsk, Russia aut Dueck I.
