The pulp and paper industry is a significant consumer of water and chemicals, constantly seeking ways to optimize processes, reduce environmental impact, and improve product quality. Poly Aluminium Chloride (PAC) has become a vital chemical auxiliary in papermaking, contributing to both operational efficiency and environmental sustainability. As a reputable supplier of PAC, we highlight its crucial roles within this demanding industry.

Key Applications of PAC in the Pulp and Paper Industry

PAC's unique chemical properties make it exceptionally useful in several stages of paper production:

  • Wastewater Treatment: Papermaking generates large volumes of effluent that contain residual fibers, fillers, dyes, and other process chemicals. PAC serves as a highly effective coagulant and flocculant in treating this wastewater, removing suspended solids and organic pollutants. This ensures that discharged water meets environmental regulations, and in some cases, allows for water recycling within the plant, reducing overall water consumption. Our high-purity PAC is an excellent choice for environmentally conscious paper mills.
  • Retention Aid: In the papermaking process, retention aids are crucial for keeping fine particles, such as fillers (e.g., calcium carbonate, clay) and fibers, within the paper sheet rather than losing them into the white water system. PAC, when used as a retention aid, helps to agglomerate these fine particles, improving the retention of valuable materials. This leads to better paper quality, reduced material waste, and improved drainage on the paper machine.
  • Sizing Agent Enhancement: Sizing agents are used to control the liquid penetration of paper. PAC can work synergistically with traditional sizing agents (like AKD or ASA) or as a component in sizing systems. It helps to fix the sizing agent onto the paper fibers, improving the efficiency of the sizing process and leading to better water resistance and printability in the final paper product.
  • Pitch and Stickies Control: During the pulping and papermaking process, natural resins (pitch) and recycled paper contaminants (stickies) can cause operational issues, leading to deposits on machinery and defects in the final paper. PAC can help to manage these issues by coagulating and precipitating pitch and sticky particles, preventing them from accumulating on equipment.

Advantages of Using PAC in Papermaking Processes

The adoption of PAC in the paper industry is driven by its performance advantages:

  • Improved Efficiency: By enhancing retention and drainage, PAC helps increase machine speed and reduce energy consumption.
  • Cost Savings: Better retention of fillers and fibers reduces raw material costs. Efficient wastewater treatment can also lead to lower effluent disposal fees and potential savings from water recycling.
  • Enhanced Product Quality: Improved sizing and retention contribute to a higher quality final paper product with better printability and strength.
  • Environmental Compliance: Effective wastewater treatment using PAC is critical for meeting environmental discharge standards and promoting sustainable manufacturing.
