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.

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.

Does PAC coagulate?

PAC acts primarily as a coagulant, helping in the aggregation of suspended particles into larger clumps that can be easily settled or filtered from water. Is poly aluminium chloride hazardous?

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 poly Aluminium chloride?

This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.

Why is poly aluminum chloride a coagulant?

Poly Aluminium Chloride exhibits several essential chemical properties that contribute to its effectiveness as a coagulant. It is highly soluble in water and capable of generating a wide range of polymeric species based on its degree of polymerization. PAC solutions are acidic due to the presence of hydrolyzed aluminum species.
