WebIon exchange is a water treatment method where one or more undesirable ionic contaminants are removed from water by exchange with another non-objectionable, or less objectionable ionic substance. Both the contaminant and the exchanged substance must be dissolved and have the same type of electrical charge (positive or negative). Web15 dec. 2009 · There are many methods available to remove divalent metal ions from solutions, among which the ion exchange is the most simple and efficient one. …
Web28 nov. 2013 · The ion exchange process was developed to remove calcium and magnesium hardness from synthetic hard water solutions by using the resin of Amberlite IR 120 in H + form. The following reactions show that the resin matrix has been converted to the H + form from Na + and the exchange reaction of calcium and magnesium has … WebThe warm lime softening process operates in the temperature range of 120-140°F (49-60°C). The solubilities of calcium, magnesium, and silica are reduced by increased temperature. Therefore, they are more effectively removed by warm lime softening than by cold lime softening. This process is used for the following purposes:
