Polyaluminum chloride (PAC) is a new and efficient inorganic polymer coagulant. It has the advantages of high turbidity removal efficiency and small impact on effluent pH, and has been widely used in water treatment processes.
With the development of science and technology and the deepening of product understanding, polyaluminum chloride is increasingly used in the paper industry.

polyaluminium chloride (PAC) can be applied in paper making. In the paper industry, PAC is often used as a coagulant in the papermaking process. It helps to remove impurities and suspended particles from the pulp, which results in a clearer and cleaner paper product. PAC is also used in the production of paper sizing agents. Sizing agents are chemicals that are used to improve the water-resistance and printability of paper. PAC can be used as a sizing agent because it forms a strong and stable bond with cellulose fibers, which are the main component of paper.
Overall, PAC is a versatile and useful chemical that can be applied in various industries, including the paper making industry.

Polyaluminium Chloride Advantages:
- Polyaluminium chloride outperforms other organic flocculants in purifying low-temperature, low-turbidity, and heavily organic-polluted raw water. This results in a treatment cost reduction of 20%-80%.
- The quick formation of large-sized floc (especially at low temperatures) and rapid precipitation service life of cellular filter of the sedimentation basin are facilitated by this chemical.
- In comparison to other flocculants, a smaller dosage of Polyaluminium chloride is required to improve the quality of treated water.
- Polyaluminium chloride displays wide adaptability to different water temperatures (in the summer and the winter) and regions (in the south and the north of China).
- It is compatible with the automatic dosing device of alum.
- Polyaluminium chloride can function over a wide range of pH values (5-9) and can decrease the pH value and basicity after processing.
