2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.

3. 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 ...

4. Magnetic water treatment - Wikipedia

   en.wikipedia.org/wiki/Magnetic_water_treatment

   As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental testing and is thus disproven. Any products claiming to utilize magnetic water treatment are absolutely fraudulent. [1]

5. Water treatment - Wikipedia

   en.wikipedia.org/wiki/Water_treatment

   Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

6. 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.
