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.

How does poly Aluminium chloride work?

Poly Aluminium Chloride is a highly efficient water treatment chemical where it works as a coagulant to extract and clump together contaminants, colloidal and suspended matter. This results in the formation of floc (flocculation) for removal via filters. The below image showing coagulation in action illustrates this process.

Why are polymeric flocculants used in industrial effluent treatment?

Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).

What is a polymeric flocculant?

In most cases, they are derived from oil-based and non-renewable raw materials (Suopajärvi et al., 2013). Commonly used polymeric flocculants include polyacrylamide, polyacrylic acid, poly (diallyl dimethyl ammonium chloride) (DADMAC), polyamine and others (Singh et al., 2000).

What is poly Aluminium chloride?

Poly Aluminium Chloride on the other hand, has been developed as an alternative. PAC hydrolyses with greater ease, obtains better coagulation, and rapidly forms flocs making this a much more efficient product. It also possesses lower doses of aluminium therefore leaving significantly fewer aluminium residuals and sludge waste product.

Why is PAC a good choice for water purification?

Known for its superior flocculation properties, PAC has emerged as one of the most effective and environmentally friendly solutions for purifying water. In this article, we explore why PAC is the preferred choice for both municipal water treatment plants and industrial wastewater management, highlighting its advantages and key applications.
