A mathematical model presented in this paper describes the dispersion and concentration ofcontaminants (fine and coarse) in porous medium with the effect of chemical reaction. Solutetransport in porous media is discussed by means of advection-dispersion equation. The effectof particle mass parameter and reaction rate parameter on the dispersion coefficient and meanconcentration of a chemical so...

Contaminants of emergent concern (CECs) in aquatic ecosystems entail a potential risk for the environment, due to their persistent behavior and adverse effect on living organisms during long-term exposition, even at residual concentrations. Conventional Wastewater Treatment Plants (WWTPs) are not designed eliminate CECs properly because treatment technologies enough remove these contaminants, w...
