What is poly Aluminium chloride (PAC)?

PAC is a range of versatile inorganic polymers, and it is characterized by strength & basicity. Poly aluminium chloride has more advantages than traditional coagulants, like alum or iron salts. It is pre-neutralized & has a charged density higher than traditional. In industry and municipal use for water treatment & purification process.

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 .

What is poly Aluminium chloride coagulant?

Poly aluminium chloride (PAC) coagulant is used in water and water waste treatment, and it is made by partial hydrolysis of acid aluminium chloride solution using a specific reactor. What is Poly aluminium chloride formula? Chemical formula for Poly-aluminium chloride is Aln (OH) mCl 3 n-m.

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

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Can PAC be used as coagulant for water treatment?

The ZPD value of PAC was also revealed that the flocculation tendency of PAC particles was very high in water, and the PAC could be used as coagulant for water treatment. Fig. 5.
