What is the difference between aluminum chlorohydrate and polyaluminum chloride?

The main difference between aluminum chlorohydrate and polyaluminum chloride is that polyaluminium chloride has a higher aluminium content and lower water content than aluminium chlorohydrate. 1. “ Aluminium chlorohydrate.”

What is aluminium chlorohydrate?

Aluminium chlorohydrate is a group of water-soluble, specific aluminium salts having the general formula Al n Cl 3n−m(O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification.

What is the difference between Pac and polyaluminium chlorohydrate?

PAC can have varying levels of basicity, depending on the manufacturing process and product formulation. High-basicity PACs contain more hydroxide ions and can significantly raise the pH of water. Aluminium chlorohydrate products typically have lower aluminum content compared to polyaluminium chloride.

Is aluminum chlorohydrate a safe coagulant for drinking water treatment?

Aluminum chlorohydrate and Polyaluminum Chloride are both commonly used for water treatment. Then, why is Aluminum Chlorohydrate selected as the safe coagulant for drinking water treatment? Form the above data comparison we can see that technical requirements of Aluminum Chlorohydrate is much stricter than Polyaluminum Chloride.

Is ACH aluminum chlorohydrate better than Pac?

The performance of ACH Aluminum chlorohydrate is much better than PAC on both the turbidity control and aluminum residue. By well controlling the dosage of ACH Aluminum chlorohydrate, aluminum residue even can't be detected in treated outlet water, with less aluminum residue. Here Below are Data of ACH to Treat Water in Different Turbidity:

Does aluminium chlorohydrate affect water pH?

Further, the high degree of neutralization of the HCl results in minimal impact on treated water pH when compared to other aluminium and iron salts. Aluminium chlorohydrate is one of the most common active ingredients in commercial antiperspirants.
