2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   A study found the mean concentration of sodium in softened water to be 278 mg/L. [23] In 2 liters of water—the amount of drinking water typically suggested for an average adult, this constitutes about 22% of the recommended sodium intake by the US CDC and may make a difference to those who need to significantly limit their sodium consumption.

3. Dealkalization of water - Wikipedia

   en.wikipedia.org/wiki/Dealkalization_of_water

   Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...

4. Backwashing (water treatment) - Wikipedia

   en.wikipedia.org/wiki/Backwashing_(water_treatment)

   The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline or when the differential pressure across the filter exceeds a set value. Water treatment filters that can be backwashed include rapid sand filters, water softening systems, pressure filters and granular activated ...

5. Drinking water quality in the United States - Wikipedia

   en.wikipedia.org/wiki/Drinking_water_quality_in...

   The Safe Drinking Water Act requires the US EPA to set standards for drinking water quality in public water systems (entities that provide water for human consumption to at least 25 people for at least 60 days a year). [3] Enforcement of the standards is mostly carried out by state health agencies. [4]

7. Total dissolved solids - Wikipedia

   en.wikipedia.org/wiki/Total_dissolved_solids

   When measuring water treated with water softeners, high levels of total dissolved solids do not correlate to hard water, as water softeners do not reduce TDS; rather, they replace magnesium and calcium ions, which cause hard water, with an equal charge of sodium or potassium ions, e.g. Ca 2+ ⇌ 2 Na +, leaving overall TDS unchanged [9] or even ...
