What is polyaluminium chloride?

Polyaluminium Chloride is a water purification material, inorganic polymer coagulant, also referred to as Poly aluminum, abbreviated as PAC, an inorganic polymer water treatment agent having a relatively large molecular weight and a relatively high charge is produced due to bridging action of hydroxide ions and polymerization of polyvalent anions.

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

Is polyaluminium chloride water soluble?

Polyaluminium Chloride is a water chemical made up of the elements aluminium, oxygen, hydrogen, and chlorine. Polyaluminium Chloride is also known as Aluminium Chloride Hydroxide and is abbreviated as PAC. Polyaluminium Chloride is a yellow colored, water soluble solid with the chemical formula [Al2 (OH)nCl6-n]m.

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 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.
