What is poly aluminum chloride (PAC)?

Poly Aluminium Chloride, commonly abbreviated as PAC, is an inorganic polymer that belongs to the family of aluminum salts. It is a compound primarily used as a coagulant and flocculant in water treatment processes.

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.

Why is PAC a good coagulant?

It serves as a highly effective coagulant and flocculant, aiding in the removal of suspended particles, colloids, and other impurities in water. PAC’s ability to form dense flocs helps in the efficient clarification and purification of wastewater, industrial effluents, and municipal drinking water.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

What is poly Aluminium chloride India?

As a prominent member of the aluminum salts family, Poly Aluminium Chloride India, or PAC, is extensively employed in water treatment, paper production, textiles, and many other sectors.

What are the advantages of Pac compared to inorganic flocculants?

Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed. The corrosivity of PAC is lower, easy to transfer, handle and operate. Drinking water and sanitary sewage.
