These figures illustrate that the predictions by both models get worse for more com- plex electrolytes, though nothing changes about the trends observed above. If we ig- nore the lower bound on the boundary layer theory, both models specifically struggle with intermediate current ranges, which is likely where mixing due to electro-osmotic flow becomes important. We can see that the simulation which already includes several more complex features, such as a simple treatment of electro-osmotic flow, already does better at predicting the experimental data than the boundary layer model. Also, something that becomes very apparent in these figures is that the water recovery in the model only starts increasing significantly once the current at which electro-osmotic flow becomes similar in magnitude to pressure-driven flow is reach, whereas the water recovery starts increasing immediately in experiment. This ob- servation either means that our estimate of the electro-osmotic flow is incorrect (the magnitude is wrong or the way it is incorporated in the model is too simplistic) or that another phenomenon is causing the water recovery to start increasing from the start in experiment. Another interesting aspect of how these models fare is whether the same scaling for current will collapse theoretical data onto a single curve as it does the experimental data. Figure 3-16 shows the theoretical data for various electrolytes obtained via the boundary layer model plotted against the same dimensionless current that allowed collapse of the experimental data. As shown in the figure, the theoretical data does not collapse on a single curve using this scaling. In fact, we can again see the minimum ion removal imposed by the assumption of zero concentration at the lower boundary. The most obvious additional discrepancy is the fact that the scaling with flow rate appears to be incorrect. In fact, by inspecting equation 3.2, we observe that the √ equation predicts that the ion removal would scale with as observed in the experimental data. Q and not linearly with Q In addition to investigating the collapse for the boundary layer model, we have also investigated it for our simulation. Figure 3-17 shows the simulation data for various electrolytes at various dimensionless currents, using the scale that allowed collapse of the experimental data. We can clearly see that this scale does not lead 92PDF Image | Shock Electrodialysis for Water Purification and Electrostatic Correlations
