What is polyaluminum chloride used for?

Industrial Applications Polyaluminum Chloride finds extensive use in various industries across Europe due to its exceptional coagulation and flocculation properties. Some key applications include: Water and Wastewater Treatment: PAC is widely used as a coagulant in water treatment processes.

What is polyaluminum chloride (PAC)?

Physical Details and Properties Polyaluminum Chloride (PAC) is a versatile chemical compound used in various industrial applications. It is an inorganic polymer with the chemical formula Aln (OH)mCl₃n-m, where n represents the degree of polymerization and m represents the number of hydroxyl groups.

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 concentration of aluminum in Pac solution?

The aluminum concentration in the PAC solution was diluted in the ranges from 5.4 to 10.8 mg L −1. The PAC solution to Ferron solution volume ratio was 10:1, which was mixed and immediately transferred to the cuvettes in the UV–vis spectrometer for absorbance measurement.

Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .

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.
