What is poly Aluminium chloride?

This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.

Why is poly aluminum chloride a coagulant?

Poly Aluminium Chloride exhibits several essential chemical properties that contribute to its effectiveness as a coagulant. It is highly soluble in water and capable of generating a wide range of polymeric species based on its degree of polymerization. PAC solutions are acidic due to the presence of hydrolyzed aluminum species.

Is poly Aluminium chloride safe?

While Poly Aluminium Chloride is generally safe for use in the prescribed concentrations, excessive exposure to PAC can have adverse effects. Long-term exposure to high levels of aluminum compounds may lead to neurological issues, bone disorders, and other health concerns.
