What is poly Aluminium chloride (PAC)?

In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.

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 .

Why is poly Aluminium chloride used in water treatment?

The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

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.
