2. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings.

3. Nanofiltration - Wikipedia

   en.wikipedia.org/wiki/Nanofiltration

   Nanofiltration is a membrane filtration process that uses nanometer sized pores through which particles smaller than about 1–10 nanometers pass through the membrane. Nanofiltration membranes have pore sizes of about 1–10 nanometers, smaller than those used in microfiltration and ultrafiltration, but a slightly bigger than those in reverse ...

4. Ion-exchange resin - Wikipedia

   en.wikipedia.org/wiki/Ion-exchange_resin

   The most common examples are water softening and water purification. In many cases, ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites. Also, ion-exchange resins are highly effective in the biodiesel filtration process.

5. Zeolite - Wikipedia

   en.wikipedia.org/wiki/Zeolite

   Zeolites are widely used as ion-exchange beds in domestic and commercial water purification, softening, and other applications. Evidence for the oldest known zeolite water purification filtration system occurs in the undisturbed sediments of the Corriental reservoir at the Maya city of Tikal , in northern Guatemala.

6. 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).

7. Polystyrene sulfonate - Wikipedia

   en.wikipedia.org/wiki/Polystyrene_sulfonate

   Polystyrene sulfonate. Polystyrene sulfonates are a group of medications used to treat high blood potassium. [1] Effects generally take hours to days. [1] They are also used to remove potassium, calcium, and sodium from solutions in technical applications. Common side effects include loss of appetite, gastrointestinal upset, constipation, and ...
