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 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 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:

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.

How to produce high basicity polyaluminum chloride and aluminum chlorohydrate?

This invention relates to a process to produce high basicity polyaluminum chloride and aluminum chlorohydrate by electrodialysis. Polyaluminum chloride (PAC) is the name given to the family of compounds defined by the formula: Where 0 < n ≤ 3m and where m ≥ 1. The degree of neutralization (i.e., the OH to A1 ratio) is known as the basicity.

What is the basicity of aluminum chlorohydrate?

One particular interest is the use of these processes to produce aluminum chlorohydrate with a basicity of about 83%. (in the case of aluminum chlorohydrate, X is Cl in the above formula and the aluminum to chloride ratio is from about 1.9:1 to about 2.1:1)
