Polyaluminium chloride

Polyaluminum chloride PAC is also commonly called water purifier or coagulant. It is a water-soluble inorganic high molecular polymer between ALCL3 and AL (OH) 3.

Application

1. Process industrial water and industrial circulating water.
2. The product can be used to reclaim mine flushing waste water and ceramic industry waste water.
3. It can be used to prevent wrinkles of leather and cloth, and can be used as excellent .
4. It can be used in cement and die casting, refining of , and sugar, and conglutination of paper.

Performance

1. Purified water is better than aluminum sulfate flocculant, and the cost of water purification is 15-30% lower than that.
2. Floc formation is fast and sedimentation speed is faster than conventional products such as aluminum sulfate.
3. The alkalinity in the consumed water is lower than that of various inorganic flocculants.
4. The source water can adapt to pH 5.0-9.0 range.
5. Low corrosivity and good operating conditions.
6. Solubility is better than aluminum sulfate.
7. The increase of salinity in the treated water is small, which is conducive to ion exchange treatment and high-purity water.
8. Adaptability to source water temperature is better than inorganic flocculants such as aluminum sulfate.
