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.

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.

How does PolyDADMAC work?

PolyDADMAC can strengthen the “net structure” formed by inorganic coagulant in water treatment to effectively capture fine suspended matter, especially in high turbidity or highly polluted water. 1.

How does PolyDADMAC affect flocculation?

The use of PolyDADMAC in combination with inorganic flocculants (such as polyaluminium chloride and aluminium sulfate) can significantly enhance the flocculation effect. After PolyDADMAC neutralizes the surface charge of the particles, the inorganic flocculants further form larger flocs through adsorption and sedimentation.

Can PolyDADMAC be used with inorganic flocculants?

Synergistic effect with inorganic flocculants The use of PolyDADMAC in combination with inorganic flocculants (such as polyaluminium chloride and aluminium sulfate) can significantly enhance the flocculation effect.

Why is PolyDADMAC a high molecular polymer?

PolyDADMAC is a high molecular polymer with a large number of cationic groups in its molecular structure, which can effectively adsorb suspended particles and colloids in water. Its main characteristics include: 1. Strong cationicity: It can quickly neutralize negatively charged suspended particles in water. 2.
