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 polyalumium ferric chloride (PAFC)?

Polyalumium ferric chloride (PAFC) is a kind of composite coagulant, which has been developed by the prehydrolyzation of AlCl 3 and FeCl 3, or prepared from hydrochloric pickle liquor or blast furnace dust .

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

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).

Does polyaluminum chloride remove turbidity?

The study compares the efficacy of polyaluminum chloride and polyacrylamide in removing turbidity, representing the number of suspended solids, under varying pH, mixing time, temperature, oil, and suspended solids conditions. Optimizing these parameters is crucial for enhancing the coagulation treatment’s efficiency.

How does polymeric aluminum chloride achieve destabilization?

Polymeric aluminum chloride (PAC) achieves the destabilization process by adsorbing onto the surface of colloidal particles and facilitating bridging. Consequently, when PAC executes both destabilization mechanisms concurrently, the process becomes more rapid and results in superior separation.
