What are the health problems caused by adding sodium chloride to the water?
…..There are no health problems caused by ion exchange water softening. The chloride ions are not added to the water. They merely pass through the resin bed during the regeneration cycle and are discharged with the regeneration waste as calcium chloride and magnesium chloride. …..Sodium ions are added to softened water in place of the calcium and magnesium that has been removed—but at an inconsequential, minute rate. …..Each 1 mg/L of calcium carbonate water hardness removed adds only 0.46 mg/L of sodium. Water with over 1200 mg/L of total water hardness would still be classified after ion exchange softening as a “Low Sodium” beverage by the U.S. Food and Drug Administration food labeling regulations because of the trivial amount of added sodium. What is the process of resin interaction with the salt? …..When the sodium chloride salt is dissolved in water to make brine, it splits into sodium (Na+) cations and chloride (Cl-) anions. The inert strong acid cation exchange resin us
