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. Uniform Plumbing Code - Wikipedia

   en.wikipedia.org/wiki/Uniform_Plumbing_Code

   Designated as an American National Standard, the Uniform Plumbing Code (UPC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of plumbing systems as a means of promoting the public's health, safety and welfare.

5. Ion exchange - Wikipedia

   en.wikipedia.org/wiki/Ion_exchange

   Ion exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening).

6. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs . If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus ...

7. 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 ...
