Hydrazine hydrate is widely used as a reducing agent or an intermediate of synthesis in various industrial sectors like water treatment (effluents, industrial boilers), chemical treatment process (metals, mine extraction) or active ingredients synthesis (pharmaceuticals and agrochemicals). Desoxidant for boiler descaling, upstream product of Methylhydrazine and many other hydrazine or Pyrazole derivatives.

A new type of water purification material, known as an inorganic polymer coagulant and commonly abbreviated as polyaluminum or PAC (Polyaluminum Chloride), is a water-soluble inorganic polymer with a chemical composition intermediate between AlCl₃ and Al(OH)₃. Its general chemical formula is expressed as [Al₂(OH)ₙCl₆₋ₙ]ₘ, where m represents the degree of polymerization and n denotes the basicity (or degree of neutralization) of the PAC product.
