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.

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 .

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.

How does polymeric aluminum chloride destabilize colloidal particles?

Polymeric aluminum chloride (PAC) achieves the destabi-lization 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 separa-tion.

What is the most effective dosage for polyaluminum chloride (PAC) & aluminum sulfate (FEC?

The findings revealed that the most effective dosages for polyaluminum chloride (PAC), aluminum sulfate (Al 2 (SO 4) 3), and ferric chloride (FeCl 3) were 20, 10, and 20 mg/L, respectively.

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.
