Abstract - This study focuses on calcium sulfate (gypsum) and calcium carbonate (CaCO 3) simple and mixed precipitations. These forms of scaling are still an issue in several industrial applications such as cooling towers and water desalination, either by thermal-based or membrane-based processes.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in industry.
The CLP Regulation ensures that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union through classification and labelling of chemicals.
Calcium sulfate, silver sulfate and mercurous sulfate are slightly soluble in water, but calcium sulfate is rarely precipitated in reactions between the calcium and sulfate ions.

Calcium sulfate is only slightly soluble in water. When it does dissolve, the ions are spectator ions. This means that they do not interact with water molecules in a way that significantly changes the pH. The pH of a saturated solution of calcium sulfate is 7.7, close to that of pure water.
Gallium Sulfate is a moderately water and acid soluble Gallium source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.

Magnesium sulfate is an inorganic salt with the formula MgSO 4 (H 2 O) x where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO 4 ·7H 2 O), commonly called Epsom salt.The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority was used in agriculture.
