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
- Process industrial water and industrial circulating water.
- The product can be used to reclaim mine flushing waste water and ceramic industry waste water.
- It can be used to prevent wrinkles of leather and cloth, and can be used as excellent .
- It can be used in cement and die casting, refining of , and sugar, and conglutination of paper.
Performance
- Purified water is better than aluminum sulfate flocculant, and the cost of water purification is 15-30% lower than that.
- Floc formation is fast and sedimentation speed is faster than conventional products such as aluminum sulfate.
- The alkalinity in the consumed water is lower than that of various inorganic flocculants.
- The source water can adapt to pH 5.0-9.0 range.
- Low corrosivity and good operating conditions.
- Solubility is better than aluminum sulfate.
- The increase of salinity in the treated water is small, which is conducive to ion exchange treatment and high-purity water.
- Adaptability to source water temperature is better than inorganic flocculants such as aluminum sulfate.
