The method presented in parts 1 and 2 for the design of simple cyclic ion-exchange processes in fixed beds is extended to the case where Na', Mg\*' and Ca\*' are all present in the saturation solution. Two properties are established: firstly that the breakthrough curves corresponding to Ca" and Na'

✦ Synopsis
The method presented in Part I, for studying a simplified ion-exchange cycle, is extended to cover the usual case of the regenerant having a total concentration different from that of the saturant. This change in total concentration, as it propagates in the column, gives rise to interference phenomena with the exchange fronts. The study of these interferences allows, as in Part I, the detailed effluent history to be predicted.

Comparative advantages of fixed bed and batch ion exchange processing are discussed. When no complementary phenomena occurs, the choice of one of the two techniques is based on a comparison between their respective adsorption efficiency for equal values of process duration, phases amounts and ionic
