It is found that the DBL near an ionexchange membrane is formed quasi-instantly under natural convection and follows the variation in solution concentration drop through the DBL (Dc): d ~ (Dc)–0.2. The fact that the value of power differs from the value predicted by Levich (–0.25) is explained by th

Although both models were observed to be able to predict solute rejection, the DSPM makes better predictions. This result can be explained as

With respect to the gravimetric methods (in which the vessel is weighed empty and then filled with a liquid of known density), the main advantages of the proposed procedure are the

In Fig. 1, experimental and predicted results for a crossflow velocity of 1 ms–1 and four TMPs are shown. For long-time scales, the permeate fluxes predicted by the model are lower than those experimentally observed. However, the shapes of the curves for flux decline with time estimated by the model

The steric, electric and dielectric exclusion (SEDE) model has been developed with the aim of investigating transport through nanofiltration (NF) membranes. The distribution of ions at the membrane/solution interfaces is described as being the result of size effects, Donnan exclusion and dielectric
