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.

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.

Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

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

Is PAC a good flocculant?

The floc function valid in water of pH 5 to pH 9 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.

Is Pac powder soluble in water?

PAC powder is easily soluble in water, allowing for convenient dosing and application in water treatment plants, wastewater treatment facilities, and other purification processes. PAC Liquid Form PAC in liquid form offers advantages in certain applications. It is often preferred when continuous dosing or automated dosing systems are required.
