What is polyaluminum chloride (PAC)?

Physical Details and Properties Polyaluminum Chloride (PAC) is a versatile chemical compound used in various industrial applications. It is an inorganic polymer with the chemical formula Aln (OH)mCl₃n-m, where n represents the degree of polymerization and m represents the number of hydroxyl groups.

Why is Pac better than other aluminum salts?

PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC. Manufacturing Process

What is polyaluminum chloride used for?

Industrial Applications Polyaluminum Chloride finds extensive use in various industries across Europe due to its exceptional coagulation and flocculation properties. Some key applications include: Water and Wastewater Treatment: PAC is widely used as a coagulant in water treatment processes.

Why is polyaluminium chloride used in water treatment?

This is the rationale behind the treatment of sewage, industrial water treatment and purification of wastewater. Polyaluminium Chloride is also used in beverage and water bottling firms to eliminate impurities in water. Natural water has several minerals that it collects in the course of flowing.

How long does polyaluminium chloride take to precipitate?

Stable PAC needs at least 9 weeks at 30o to precipitate. The presence of water during the process will be evaporated in the reactor that produces steam. Finally, Polyalumunium chloride contains more than 50% Al2O3. Polyaluminium chloride is used in the treatment of drinking portable water and wastewater treatment.

What is PAC used for?

Some key applications include: Water and Wastewater Treatment: PAC is widely used as a coagulant in water treatment processes. It effectively removes suspended solids, organic matter, and contaminants from water, making it suitable for drinking water purification, municipal wastewater treatment, and industrial wastewater treatment.
