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 polyaluminium chloride (PAC)?

Polyaluminium Chloride (PAC) is a versatile chemical used extensively in water treatment and various industrial processes. Its growing importance across multiple sectors underscores its effectiveness in treating wastewater, purifying drinking water, and meeting the stringent environmental standards required today.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Can PAC be used as coagulant for water treatment?

The ZPD value of PAC was also revealed that the flocculation tendency of PAC particles was very high in water, and the PAC could be used as coagulant for water treatment. Fig. 5.

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 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.
