Water purifiion is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purifiion may also be carried out for a variety of other purposes, including medical, pharmacological, chemical
Calcium chloride is used as a drying and dehydrating agent for organic liquids and gases and for solids in desicors. Common appliions include brine for refrigeration plants and ice and dust control on roads. Use of calcium chloride and urea has been reported

Since calcium acetate has an acetate-to-calcium ratio of 2:1, double the stoichiometric amount was used, as was found necessary by Chiang et al. 5 In order to limit the presence of undesired impurities in the generated PCC, the leachate solution should be subjected to further purifiion before being carbonated; this is another novelty of the proposed syiotic process.
Dr. Ms. Guixin (Susan), Ph.D (Switzerland-Institute for Inorganic Chemistry, Zurich, Switzerland) Calcium Sulfate Submicron: Calcium sulphate (CaSO4) occurs in nature in both the anhydrous and the hydrated form. It is found firstly as the mineral known as anhydrite, however the latter is apparently best known as alabaster or gypsum..

The present invention relates to a solid bleach containing form comprising a tablet wherein said tablet is comprised of calcium hypochlorite and one or more calcium sequestering agents. A laundry process using a solid bleach containing form comprising calcium
Calcium is an alkaline-earth metal that is an important component of the cell walls of aquatic plants, and of the bones and shells of aquatic animals. Calcium ions find their way into water as it flows over rocks that contain calcium, such as limestone and gypsum.
The amplitude analysis of Ca 2+ transients can be used to study the influence of various substances on the calcium entry that participates in neurotransmitter release 33. Figure 2 : The averaged Ca 2+ transient measured in the frog NMJ.

Other high quality greases use metal to metal to generate the temperature 90 to 130 C necessary to activate the chemical E.P. used in boundary lubriion protection. Grease’s E.P. solids offer the advantage of giving a continuos E.P. action irrespective of temperature and long before boundary lubriion conditions occur.
metal ions in cells will prefer Mg over Ca ions. Neutral 0 species will select Ca2+ over Mg2+ ions because of their low polarizability and low electric field strength. Coordination chemistry has been used to describe the ability of the Mg2+ ion to form multidentate
