An antiscalant is a chemical or pre-treatment chemical that prevents the formation of scale, or crystallized mineral salts, commonly used in water purification systems, pipelines and cooling tower applications. Antiscalants are also known as scale inhibitor agents. Scale formation occurs when the concentration of dissolved salts in water ...

An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Sodium hexametaphosphate (SHMP) is a salt of composition Na 6 [(PO 3) 6]. [3] Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO 3), of which the hexamer is one, and is usually the compound referred to by this name.
Antiscalant prevent scale formation by three mechanisms, namely threshold inhibition, crystal modification and dispersion. [10] Threshold inhibition is when antiscalant molecules adsorb on crystal nuclei and halt their nucleation process, whereas crystal modification and dispersion are the ability of antiscalants to stop the growth and/or ...
DTPMP is normally delivered as salts, because the acid form has very limited solubility in water and tends to crystallize in concentrated aqueous solutions.
[4] [1] In addition, it is a degradation product of other aminophosphonates, which have applications as antiscalant and water treatment. [5] AMPA was found in the final effluent of some wastewater treatment plants at concentrations of up to 10μg/l. [6] AMPA can be detected after membrane filtration. [7]
Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.
