Dealkalizers are most often used as pre-treatment to a boiler and are usually preceded by a water softener. Alkalinity is a factor that most often dictates the amount of boiler blowdown . High alkalinity promotes boiler foaming and carryover and causes high amounts of boiler blowoff.
The source says: "much of the groundwater in Kansas is hard or extremely hard, softening can add significant amounts of sodium.", "If the liquids you drink each day have less than 100 mg/L of sodium, it probably adds less than 5 percent of the sodium content of the average adult’s diet.", plus the example they give is for very hard water ...

Water softeners are usually regenerated with brine containing 10% sodium chloride. [7] Aside from the soluble chloride salts of divalent cations removed from the softened water, softener regeneration wastewater contains the unused 50–70% of the sodium chloride regeneration flushing brine required to reverse ion-exchange resin equilibria.
