What is poly Aluminium chloride (PAC)?

Poly Aluminium Chloride (PAC) has emerged as a highly effective and versatile water treatment chemical, playing a vital role in ensuring access to clean and safe water. This article provides a comprehensive overview of PAC, its properties, applications, benefits, and manufacturing process. What is PAC?

Why is polyaluminium chloride important during water treatment process?

Polyaluminium chloride has several features important during water treatment process, and the features are outlined in the following list:- PAC helps speeding up the process of flocs formation, and the settling of the flocs at the bottom. The process makes flocs that are formed easier to be filtered out.

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.

What is poly Aluminium chloride?

Poly Aluminium Chloride (PAC) is a group of aluminium chlorohydrates with the general formula [Al2 (OH)nCl6-n]m. This polymeric inorganic coagulant finds extensive use in the treatment of water and wastewater. PAC is available in various forms, including powder, liquid, and granular, with varying basicity and aluminium content.

How PAC is used in water purification?

The solid powdered PAC from us is made by excellent spray drying technology. It is used as a recoagulant in drinking water purification, as an antiperspirant in deodorants and flocculant in waste water treatment. The neutralization process of the substance HCl results shows that water PH isn’t influenced by using PAC to purify water.

What is polyaluminium chloride?

Polyaluminium chloride is the one of the first chemicals that are added in the water during the coagulation process. The compound is highly charged, where it reacts and neutralizes the negative charge on dirt and other dissolved particles. This will allow the compound to bind together to form larger particles.
