Description
This lecture introduces the modeling of kinetics in water quality using PHREEQC software. It covers the comparison of reaction time scales, Damköhler numbers, and the use of KINETICS and RATES keywords. The lecture explains the need for kinetic modeling based on transport time scales and reaction time scales, emphasizing the importance of equilibrium reactions and the consideration of diffusion and advection-dominated transport. It also delves into the detailed syntax and parameters of the KINETICS keyword, providing examples of kinetic biodegradation models. The presentation concludes with common pitfalls and examples showcasing the numerical solutions of kinetic reactions in PHREEQC.
