Optimization of Membrane Processes with Applications in Transport and Adsorption of Nitrate Ions

Abstract:

In the present work, the optimization of membrane processes used for the adsorption of nitrate ion, present in different concentrations, in drinking water, was approached. The adsorption was studied by help of some composite membranes with pores dimensions of 1.0mm. The transport and adsorption were numerically modeled using COMSOL program and laboratory practice. The results presented in this paper represents a possible answer to many challenges in terms of numerical models for the transport of pollutants in drinking water, through a particular methodology for estimating the velocity and dispersion coefficients. The aqueous solution transport and adsorption were performed using the program COMSOL for surface (2D) and volume (3-D). Keywords: membrane transport, diffusion process, adsorption, COMSOL program, dispersion coefficients
