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.

Is there an alternative preparation procedure for polyaluminium chloride (PAC)?

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper.

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.

Why are Pac solutions acidic?

PAC solutions are acidic due to the presence of hydrolyzed aluminum species. The effectiveness of PAC can be influenced by various factors such as pH, temperature, and the concentration of contaminants in the water. The production of Poly Aluminium Chloride involves a series of chemical reactions.

Why is PAC a good choice for water treatment?

The PAC chemical formula and structure make it an excellent choice for water treatment, where it aids in the removal of contaminants and impurities, ensuring cleaner and safer water for various purposes.
