What is polyaluminum chloride (PAC)?

Sci.882 012014DOI 10.1088/1755-1315/882/1/012014 Polyaluminum chloride (PAC) is commonly used as a chemical in the water treatment industry, deodorant and paper-making. The PAC is a complex inorganic substance between hydroxyl and aluminum ions that gradually takes place chlorination with its general formula of Al x (OH) y Cl 3x-y.

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 PAC in chemistry?

The PAC is a complex inorganic substance between hydroxyl and aluminum ions that gradually takes place chlorination with its general formula of Al x (OH) y Cl 3x-y. It has the ability to coagulate suspended solid or dispersed colloid within water perform easily precipitated flock.

Which raw materials are used to make liquid PAC?

It has the ability to coagulate suspended solid or dispersed colloid within water perform easily precipitated flock. The raw materials used for manufacturing liquid PAC consists of hydrated alumina (Al (OH) 3), hydrochloric acid (HCl), sulfuric acid (H 2 SO 4) and calcium carbonate (CaCO 3).

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 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.
