Abstract

Simulation of Fluoride Transport through Fine Sand Column Experiments

In this study, an attempt was made to estimate linear sorption, Freundlich and Langmuir isotherms of fluoride through fine sand via batch sorption. These sorption isotherms were used to simulate fluoride transport through fine sand column experiments. Subsequently, implicit finite difference numerical technique was used to solve one-dimensional advection-dispersion transport equation. Transport of fluoride through a porous bed was simulated with linear and nonlinear sorption models. Results show that fluoride breakthrough curves simulated by using the Freundlich nonlinear sorption model reveal good agreement with experimental observed data. Further, it was also seen that the Freundlich nonlinear isotherm model gives best fit of concentration profiles as compared to Langmuir sorption model.
