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.

Is polyaluminum chloride a stable product?

Stable product. No AlOH formation Polyaluminum chloride (PAC) and aluminum sulfate make use of agglutinative properties in the treatment of water for municipal water supplies, sewage wastewater, and industrial wastewater to adsorb (flocculate) and precipitate the fine particles and suspended solids in the processing of suspensions.

What is poly aluminum chloride (PAC)?

Poly Aluminum Chloride (PAC) is a coagulant widely used in water treatment processes. It is available in both powder and liquid forms, offering flexibility and ease of use in various applications. PAC is a chemical compound composed of aluminum and chlorine, known for its excellent coagulation and flocculation properties.

What is the chemical formula for polyaluminium chloride?

Polyaluminium Chloride is a yellow colored, water soluble solid with the chemical formula [Al2 (OH)nCl6-n]m. The chemical comes in the forms Polyaluminium Chloride (PAC) 28% and Polyaluminium Chloride (PAC) 30%. Polyaluminium Chloride has many industrial uses but primarily it is used in the processes of flocculation in water treatment industries.

How to test polyaluminum chloride PAC solution?

Test Solution Configuration according to the weight ratio (W/W), generally with 2 ~ 5%. For example, prepare 3% solution: weigh 3g of polyaluminum chloride PAC solid, put it in a 200ml measuring cylinder, add about 50ml of clear water, dilute it to 100ml scale after it is dissolved, and shake it well.

What is polyaluminium chloride (PAC) used in paper sizing?

For polyaluminium chloride (PAC) used in paper sizing, the dosage is one of three parts of aluminium sulfate, which is calculated as 2-3% according to absolute dry paper, and is used in decolorization and clarification of sugar industry.
