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 .

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.

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.

Why is polyaluminum chloride used as a catalyst?

Polyaluminum chloride (PAC) was used as a catalyst for the first time to synthesize bis (indolyl) methane compounds. PAC catalyst has the advantages of high efficiency, green, mild and recyclable. Al O polynuclear cations in PAC may have a synergistic catalytic effect.

What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC) is a classic inorganic polymer material, which has the advantages of easy preparation, low cost, and high efficiency in the field of water treatment and other areas of environmental protection [1, 2].

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.
