    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.

  3. Thomas Clark (chemist) - Wikipedia

    en.wikipedia.org/wiki/Thomas_Clark_(chemist)

    He became known for the discovery of the phosphate of soda, and the process of lime softening of hard water the 'Clark process'. A Clark degree (°Clark) of water hardness is defined as one grain (64.8 mg) of CaCO 3 per Imperial gallon (4.55 litres) of water, equivalent to 14.254 ppm. and 10^5 parts of water

  4. 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.

  5. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Precipitative softening: [4]: 13.12–13.58 Water rich in hardness (calcium and magnesium ions) is treated with lime (calcium oxide) and/or soda-ash (sodium carbonate) to precipitate calcium carbonate out of solution utilising the common-ion effect. Electrodeionization: [9] Water is passed between a positive electrode and a negative electrode.

  6. Soap scum - Wikipedia

    en.wikipedia.org/wiki/Soap_scum

    Soap scum or lime soap is the white solid composed of calcium stearate, magnesium stearate, and similar alkaline earth metal derivatives of fatty acids. These materials result from the addition of soap and other anionic surfactants to hard water .

    en.wikipedia.org/wiki/Carbonatation

    The carbonatation process is used in the production of sugar from sugar beets.It involves the introduction of limewater (milk of lime - calcium hydroxide suspension) and carbon dioxide enriched gas into the "raw juice" (the sugar rich liquid prepared from the diffusion stage of the process) to form calcium carbonate and precipitate impurities that are then removed.
