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.”

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.

Can aluminum chlorohydrate treat water in different turbidity?

Here Below are Data of ACH to Treat Water in Different Turbidity: Aluminum chlorohydrate (ACH) can effectively coagulates over a broader pH range (as high as 5-9.5) than traditional metal salts and lower basicity polyaluminum chloride. It really do a good job in the controlling of aluminum residue.

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:

What is the difference between Alum and poly Aluminium chloride?

The cost of poly Aluminium Chloride is roughly twice/thrice that of Alum, which is $0.4/ Kg. Regarding the impact on treated water, the increase in chloride from poly Aluminium Chloride is much lower than the sulphate increase from Alum, resulting in lower overall increases in the TDS of the treated water.
