On ion exchange through porous membrane Wang, Qiming


In this talk we discuss ion exchange through porous membrane as a model for hemodialysis. A simplified one-dimensional problem has been derived based on matched asymptotic analysis and we present results to show the effect of the electric fields and membrane porosity on the solute transport between blood and dialysate regions. The resulted equations appear to be of mixed types and fully-coupled. Numerical simulations are carried out to probe the nonlinear structure of the partial differential equations (PDE) system and insight is gained on the control of solute distribution and transport across the membrane via a number of system parameters.
