2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   As water is heated, minerals will crystallize on these seeds, instead of the plumbing system. The dissolved minerals become insoluble solid particles in suspension, passing through the system without binding to plumbing surfaces. [18] Alternatives to ion-exchange water softeners exist, see table below.

3. Lime softening - Wikipedia

   en.wikipedia.org/wiki/Lime_softening

   Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process) [1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation.

4. 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 ...

5. Ion exchange - Wikipedia

   en.wikipedia.org/wiki/Ion_exchange

   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.

6. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Permanent water chlorination began in 1905, when a faulty slow sand filter and a contaminated water supply led to a serious typhoid fever epidemic in Lincoln, England. [44] Alexander Cruickshank Houston used chlorination of the water to stem the epidemic. His installation fed a concentrated solution of chloride of lime to the water being treated.
