Problem in electrodialysis process (separation process under electric field)

I have some problems with this process. This process is about separation under electric field. For my case, NaCl solution is fed in the the channel applied electrical power then Na+ and Cl- will move through te membrane to the opposite charge. For this process we can separate Na+ or Cl- out of the initial solution.

For my question,

1. I suspect that if we use Nernst-Planck equation, How do I define the voltage drop in the cell (Just only for two electrode. lets say the potential drop is 6 volts, the potential I define in anode is 6 and cathode is 0 right?)

2. If I would like to model this process in recirculation process, I will define the outlet concentration of the 1st loop as the inlet concentration of 2nd loop << Do I think in the right way? and if it's ok for this solution how can I define for this problem


Thank you everybody for your help
