Dynamical Behaviour of As(V) and Se(IV) Adsorption in Biofilters: Analysis of Dimensions, Flux and Removal Percentage

In this work, we study the dynamical behaviour of As(V) and Se(IV) absorption in a biofilter through a mathematical simulation, comparing dimensions, flux, and removal percentage in packed columns. From the numerical simulation we obtained breakthrough curves. When comparing the experimental and numerical breakthrough curves, the best correlation gives \(R^{2}=0.9825\). A set of columns with different dimensions and feed streams were simulated. “The higher and lower” calculated values in the adsorption of selenium (IV) were 3 and 17 %, respectively, whereas the corresponding values for arsenic (V) adsorption were 6 and 17 %, respectively.
