Material balances will not be developed here, as each stage of the plant can be represented by the diagram shown in figure 1 for a counter-current exchange. Material transfers can then be presented in the form of a distribution diagram, with the solute concentration in the wash liquid (x) on the abscissa and the solute concentration in the cake interstitial liquid (y) on the...
