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 .

What are the benefits of poly aluminum chloride in water treatment?

One of the effective reasons for using poly aluminum chloride in water treatment is its availability and cost-effectiveness. Other notable benefits include: poly aluminum chloride is an inorganic compound found in the form of yellow solid powder and is one of the most important compounds in the water and wastewater treatment industries.

What is poly aluminum chloride?

Eventually, these particles are bonded together by poly aluminum chloride and possibly other auxiliaries and settled. Poly aluminum chloride has long been used as an effective and efficient material for the treatment of municipal water, wastewater, and industrial effluents.

How to remove colloidal materials and water impurities from poly aluminum chloride?

One of the materials used for this purpose is poly aluminum chloride. To remove colloidal materials and water impurities, two mechanisms must be used: engaging with sediment clots and stabilizing the electrical charges of the material.

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.
