A Coupled Model for Transport, Geochemistry and Redox Processes

Zusammenfassung
A reactive multicomponent chemical transport model to describe redox processes during bank-filtration dealing with equilibrium chemistry and Kinetics of biodegradation is presented. The model approach considers hydrodynamic transport, biodegradation kinetics and equilibrium chemistry speciation. Due to their different mathematical character the transport and reaction model subsets are coupled by a two step procedure (“operation splitting”). The multi species hydrodynamic advection-dispersion subset is a partial differential equation system, the Kinetics subset are ordinary differential equation systems, and the equilibrium subset is a nonlinear algebraic equation system. The model was set up using user friendly software tools as ModelMaker 3 an MATLAB4 which offer powerful tools to solve partial differential and ordinary differential equation systems. The model is demonstrated to three test-cases typical for river bank-filtration and verified by available geochemical software. Topic: Modelling and simulation of environmental systems
