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 poly aluminum chloride (PAC)?

Poly Aluminum Chloride (PAC) is a highly efficient coagulant widely used in water treatment processes, particularly for drinking water and industrial wastewater. Known for its superior flocculation properties, PAC has emerged as one of the most effective and environmentally friendly solutions for purifying water.

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.

Can a cationic polymer predominate PAC solution?

It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated. The mode of preparation has a dramatic effect on the composition of PAC preparation.

Should cationic organic flocculants be more effective?

In principle, cationic organic flocculants should be more effective in dealing with negatively charged contaminants or particle suspensions, such as clay and dye.

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.
