What is polyaluminium chloride?

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant. It is a yellow solid powder that is widely used in water treatments. 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.

Which is better PAC or other aluminum salts?

It is a yellow solid powder that is widely used in water treatments. 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 poly Aluminium chloride?

Poly aluminium chloride is a yellow to brown powder with a slight chlorine odor. It is corrosive and causes irritation upon contact with skin, eyes, and if inhaled or ingested. Proper precautions and personal protective equipment should be used when handling. 1. Product Identification and Company

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

Can PAC be applied to water with broad pH range?

It can be applied to water with broad pH range. 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.

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.
