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.

Can anionic polyacrylamide be used as coagulant aid with ferric sulphate and polyaluminium chloride?

It is important to point out that the optimal coagulant dose can be reduced when anionic polyacrylamide is used as coagulant aid with ferric sulphate and polyaluminium chloride, thus decreasing treatment costs. 3.10. Mechanisms of the process

Does anionic polyacrylamide improve the coagulation–flocculation process?

The use of anionic polyacrylamide had little effect on this cost but improved the coagulation–flocculation process, leading to a significant increase in the settling speed and reduction in the volume of sludge produced. Table 7.

What are the advantages of polyaluminum chloride?

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. The suitable PH value range is wide (5-9), and the PH value and basicity of treated water decrease little.

Why should we use Pam instead of inorganic flocculant?

In treatment, using organic flocculant PAM instead of inorganic flocculant, the water purification capacity can be increased by more than 20% even if the sedimentation tank is not reformed. So at present, many large and medium-sized cities in the water supply shortage or poor water quality, are using PAM as a supplement.

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.
