Mixed Bed Ion-exchange Modeling for Divalent Ions in a Ternary System

Film controlled mixed bed simulations for divalent ions in a ternary system were studied in this work. The presence of divalent ions influences the electric field produced as a result of difference in ionic mobilities of the ions. Flux expressions, particle rates, and column material balances are combined and appropriate numerical methods applied to analyze the column effluent concentrations for all the ionic impurities. The model is tested for wide range of conditions. Mathematical modeling was complex and a generalized theoretical model was developed with assumptions where necessary
