Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

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.

How to use polyaluminum chloride?

Usage :1. Dissolve solid polyaluminum chloride into liquid by adding 1:3 water, and then dilute it with 10-30 times water to the required concentration before use. 2, dosage can be determined according to the different turbidity of raw water, the best dosage, generally raw water turbidity in 100-500mg/L, each thousand tons of dosage is 10-20kg.

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

What is polyaluminum chloride?

[English name] Polyaluminium Chloride, abbreviated PAC. [Technical standard] Product quality in line with national GB15892-2003 standard. Compared with other coagulants, polyaluminum chloride has the following advantages: wide application range, wide adaptability to water. Easy to quickly form large alum flower, good precipitation performance.
