What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.

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 effective is PAC in water treatment?

PAC’s effectiveness in water treatment begins with its remarkable coagulation and flocculation properties. Upon introduction into the water, PAC undergoes a series of chemical reactions that lead to the formation of larger flocs. These flocs act as molecular nets, efficiently trapping suspended particles, and colloids.

How effective is a molecular ballet PAC in water treatment?

1. Coagulation and Flocculation: A Molecular Ballet PAC’s effectiveness in water treatment begins with its remarkable coagulation and flocculation properties. Upon introduction into the water, PAC undergoes a series of chemical reactions that lead to the formation of larger flocs.

Can polymeric PAC be used for water treatment?

Several researchers have investigated the synthesis, of PAC and its performance for water treatment. The results shows that various polymeric species of PAC yield (Al b species) are obtained and different performance efficiencies for water treatment are reported in the literature [21, 24].

Is PAC a sustainable coagulant?

Reduced Sludge Generation: A Sustainable Advantage In comparison to conventional coagulants like aluminium sulfate (alum), PAC offers a sustainable advantage with its reduced sludge generation. The formation of sludge during water treatment is a concern both environmentally and economically.
