Dynamic Modelling And Simulation of Rotating Biological Contactors
Rotating Biological Contactor is a remediation technology used in the secondary treatment of wastewater (domestic and biodegradable industrial wastes). In this work, a mathematical model for rotating biological contactors (RBC) is presented, which encapsulates the consumption of soluble substrate in the developed bio-film attached to the disk of a rotating biological contactor. The model describes the consumption of the substrate and oxygen in the bio-film, and in the trough assuming the liquid in the trough is completely mixed, and the rates of substrate and oxygen utilization within the bio-film follow Monod kinetics. The numerical solution of the model agrees with the experimental data reported by other workers. The simulation also predicts the performance of RBCs in the event of any fluctuations in the flow rate and concentration of the soluble BOD5 in the influent wastewater stream. The developed model can be used in the future to aid in the optimization of the performance of RBCs.
