The papermaking industry relies on precise chemical formulations to achieve optimal product quality and efficient production processes. Among these, Polyaluminium Chloride (PAC) stands out as a highly versatile and effective chemical agent. As a premier supplier of PAC in China, we provide insights into how paper manufacturers can leverage PAC to enhance their operations.

PAC's Role in Paper Production

Polyaluminium Chloride (CAS 1327-41-9) functions primarily as a coagulant and retention aid in the papermaking process. Its unique chemical properties allow it to effectively:

  • Improve Retention and Drainage: PAC helps to retain fine fibers, fillers, and sizing agents within the paper web, thereby improving paper formation and strength. It also aids in faster drainage of water from the pulp slurry, increasing machine speed and productivity.
  • Enhance Sizing Efficiency: In processes involving rosin sizing, PAC acts as a precipitant, improving the efficiency of the sizing agent. This leads to better water resistance and printability of the final paper product.
  • Control Pitch and Stickies: By coagulating dispersed hydrophobic particles (pitch and stickies), PAC helps to prevent their deposition on machinery, reducing downtime and improving product quality.

Wastewater Treatment in Papermaking with PAC

Papermaking generates significant wastewater volumes that require effective treatment before discharge. Polyaluminium Chloride is an indispensable tool for this purpose:

  • Effective Turbidity and Color Removal: PAC efficiently coagulates suspended solids, organic matter, and dyes present in paper mill effluent, significantly reducing turbidity and color.
  • Sludge Reduction: Compared to traditional coagulants like aluminum sulfate, PAC often results in denser, more easily dewatered sludge, reducing disposal volumes and associated costs.
  • Broad pH Applicability: Our PAC products are effective across a wide pH range, making them adaptable to various effluent compositions found in different paper mills.
