In the Literature 1 you can find the following values for selectivity coefficients and separation factors (Table 6). The resin has a standard exchange capacity of 1,4 eq/L and a density of 0,7 kg/L. We want to eliminate anions from the water so we have to use an anionic resin. Table 5: Composition of the water used in this example Anion Lets take water with the following composition: Determine the percentile distribution of the occupied sites in the resin by the different ions.Determine the maximum amount of water that can be treated per liter of resin before breakthrough occurs.Determine the equilibrium composition of the resin, thus calculating how much of the Exchange capacity is used by the different ions. Determine the separation factor for an ion with respect to the other ions in the water.The following points are treated in the example: You cannot send data if you don't give your name, country, Phone and Email.Įxample calculation to illustrate the equations used by the calculator: Please fill in the fields in the table Contact Information. You can send the values in the calculator to Lenntech to determine the best resin for your application. Table 4: Output table for equilibrium composition and percentile distributions for occupied sites on the resin Table 3: Table for some sizing parameters for an ion exchange installation Table 2: Input table for cation concentrations Cations Table 1: Input table for anion concentrations Anions There is an example under the calculation tables to show how the calculations are made by the calculator. But again be careful, the calculations are based on theoretical formulas and are not corrected with results from real ion exchange water treatment plants. The calculator also shows some calculations that are needed for the sizing of an ion exchange installation. This calculator is based on theoretical calculations and explains how to use selectivity coefficients, separation factors and how to determine the maximum volume of water that can be treated with a resin before breakthrough happens.
