Pore Scale Modelling for a Porous Membrane

If I do pore scale modelling in a confined space for small plants or a reservoir, by direct pore space, reservoir modelling or network modelling using Navier-Stokes, Boltzmann method - is that valid for contaminant removal by using a porous membrane or can it be effective in water treatment? Is it viable to succeed in near future in wastewater treatment areas as well?
