Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

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 .

Does polyaluminium chloride coagulant affect the structure and diversity of pollutants?

The polyaluminium chloride (PAC) coagulant was applied to determine the impact of the treatment process on the structure and diversity of these pollutants in urban drinking water.

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].

Which chemicals can be used as coagulants for water treatment?

There are a large number of chemicals that can be used as coagulants for water treatment, which include inorganic based coagulants, organic based coagulants and hybrid materials coagulants. Aluminum sulfate, ferric chloride, ferric sulfate and polyaluminum chloride are inorganic based chemicals which can be used for water treatment .

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.
