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 the treatment capacity of polyaluminium chloride?

Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing.

What is PAC (Polyaluminium chloride)?

The PAC (Polyaluminium Chloride) enjoys wide-range adaptability for different-temperature source water and a good solubility. PAC is slightly corrosive and easy for operation, and it is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

Is Pac better than aluminum sulfate & aluminum chloride for removing turbidity & nom?

Moreover, the performance of synthesized PAC was also very much higher as compared with aluminum sulfate and aluminum chloride for removing turbidity and NOM from synthetic water samples. The coagulant dose and the lime required of synthesized PAC were reduced more than two folds relative to aluminum sulfate and aluminum chloride doses.

What is the performance of synthesized PAC compared with aluminum sulfate?

The performance of synthesized PAC compared with aluminum sulfate, aluminum chloride and commercial PAC for water treatment. 4. Conclusion The synthesis of PΑC results revealed that the low concentration of aluminum chloride favored to the formation of Αl b species of PΑC and the high concentration preferred to the formation of Αl c species of PΑC.

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].
