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 .

Do polyalu-minum chloride and polyacrylamide remove turbidity?

The study compares the eficacy of polyalu-minum chloride and polyacrylamide in removing turbidity, representing the number of suspended solids, under varying pH, mixing time, temperature, oil, and suspended solids con-ditions. Optimizing these parameters is crucial for enhancing the coagulation treatment’s eficiency.

Is polyaluminum chloride a coagulation-flocculation process?

In a study by Zarei Mahmudabadi et al. (2018) on wastewater treatment from the ceramic-tile industry, a modified coagulation–floccula-tion process involving polyaluminum chloride (PAC) with anionic (A300), cationic polymer (C270), and nonionic pol-ymers was investigated.

Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .

What is anionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).

What is aluminium chloride used for?

ATERIAL & FUNCTIONPOLYALUMINIUM CHLORIDE is a slightly acidic source of aluminium used (with soda ash) as a flocculating agent for the clarifica ion of bore water. It is sold as the powder (solid) in 25 kg bags, and in liquid form (20, 30, 40% solution).POLYALUMINIUM CHLORIDE does not flocculate until the pH of the water has
