POLY ALUMINIUM CHLORIDE

Product Description

Poly Aluminium Chloride (PAC) is a water-soluble polymeric coagulant that contains aluminum (Al), chlorine (Cl), and oxygen (O). It is typically used in water treatment processes to remove impurities such as suspended particles, organic matter, and other contaminants from water. The exact chemical composition of PAC can vary depending on the manufacturing process, but in general, it is described by the following formula:

Aln(OH)mCl(3n-m)

Aln(OH)mCl(3n-m)

Where:

• Al (Aluminum) is the central metal atom.
• Cl (Chlorine) is part of the structure.
• OH (Hydroxide) groups are present.
• n and m represent the variable number of aluminum atoms and hydroxide ions.

Components of Poly Aluminium Chloride:

1. Aluminum oxide (AlO): Typically around 40-50% by mass.
2. Chlorine (Cl): Present as part of the chloride ion (Cl»).
3. Water (HO): Often present in hydrated form, contributing to the structure and properties of PAC.
4. Hydroxide groups (OH»): Vary in number depending on the specific formulation of PAC.

The exact ratio of aluminum, chlorine, and hydroxide ions in PAC varies depending on the specific grade or formulation, but typically, PAC contains around 10“18% aluminum oxide (AlO) by weight.

Poly Aluminium Chloride is used primarily as a flocculant in water treatment, as it is highly effective in coagulating suspended particles, making them easier to remove from water
