The pulp and paper industry relies heavily on efficient water management and chemical additives to produce high-quality paper products while minimizing environmental impact. Poly Aluminium Chloride (PAC) has emerged as a key chemical in this sector, serving multiple functions from wastewater treatment to improving paper properties. As a reputable manufacturer and supplier of PAC, we are dedicated to supporting the papermaking industry with advanced chemical solutions.

PAC's primary role in papermaking encompasses two main areas: process water clarification and wastewater treatment. The extensive use of water in paper production means that both incoming raw water and process water require effective purification. PAC acts as an excellent coagulant and flocculant, efficiently removing suspended solids, organic matter, and color from water sources, ensuring a cleaner input for papermaking machinery and processes. This not only helps maintain the quality of the final product but also reduces the load on wastewater treatment facilities.

Beyond water purification, PAC also plays a direct role in enhancing paper quality. It functions as a retention aid, helping to retain fine fibers and fillers within the paper sheet, thereby improving paper strength, opacity, and surface smoothness. Additionally, PAC is utilized as a precipitant for rosin sizing agents. When used in conjunction with rosin size, it neutralizes the charge, allowing the rosin to precipitate evenly onto the pulp fibers. This improves the paper's sizing resistance, making it less susceptible to ink feathering and bleed-through, crucial for printing and writing papers. When looking to purchase PAC for these applications, ensuring the right grade and basicity is vital for optimal performance.

The environmental benefits of using PAC in the paper industry are also significant. By improving the efficiency of wastewater treatment, PAC helps mills comply with stringent environmental regulations. Its effectiveness in reducing the total suspended solids (TSS) and chemical oxygen demand (COD) in mill effluents contributes to cleaner water discharge, supporting sustainable forestry and manufacturing practices. Many paper manufacturers seek to buy Poly Aluminium Chloride for its dual benefits of process improvement and environmental responsibility.
