The process expanded in use as the other benefits of the process were discovered. Lime softening greatly expanded in use during the early 1900s as industrial water use expanded. Lime softening provides soft water that can, in some cases, be used more effectively for heat transfer and various other industrial uses.

An alternative water treatment is called water conditioning, in which minerals remain in the water, but are altered so they do not form scale. Although the United States has standards for measuring the minerals in water, it does not have standards for measuring scale forming ability of water. Instead, US researchers use the German DVGW-W512 ...
An 1836 lithograph of tortilla production in rural Mexico Bowl of hominy (nixtamalized corn kernels). Nixtamalization (/ ˌ n ɪ ʃ t ə m ə l ɪ ˈ z eɪ ʃ ən / nish-tə-mə-lih-ZAY-shən) is a process for the preparation of maize (corn), or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates), [1 ...

The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, [8] thus the complex and varied physical nature of lime products. An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes.
Rotary lime kiln (rust-colored horizontal tube at right) with preheater, Wyoming, 2010 Traditional lime kiln in Sri Lanka. A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is: CaCO 3 + heat → CaO + CO 2
The exact chemical reaction leading to the synthesis of lime sulfur is generally written as: Ca(OH) 2 + x / 8 S 8 → CaS x + by-products (S 2 O 2− 3, SO 2− 3, SO 2− 4) as reported in a document of the US Department of Agriculture (USDA).
