NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing specialized chemical solutions for various industries, including the vital pulp and paper sector. This article highlights the critical role of Polyaluminium Chloride (PAC) in effectively treating paper industry wastewater and facilitating water recycling.

The pulp and paper industry is a significant consumer of water, and its wastewater streams often contain a complex mixture of suspended solids, organic matter, dyes, and dissolved chemicals. Effective treatment of this wastewater is essential not only for environmental compliance but also for the industry's long-term sustainability and operational efficiency. Polyaluminium Chloride (PAC) has emerged as a key chemical in achieving these goals.

PAC functions as a highly effective coagulant and flocculant in paper mill wastewater treatment. Its ability to neutralize the charge of suspended particles, including cellulose fibers, fillers, and pigments, allows them to aggregate into larger flocs. These larger flocs are more easily removed through subsequent processes such as sedimentation, flotation, or filtration. By employing PAC, paper mills can significantly improve the clarity of their effluent, reduce the concentration of total suspended solids (TSS), and lower the chemical oxygen demand (COD) and biological oxygen demand (BOD) of the wastewater.

The benefits of using polyaluminium chloride in this sector are multifaceted. Firstly, its efficiency in flocculation leads to a reduction in the volume of sludge produced compared to traditional coagulants. This translates to lower sludge dewatering and disposal costs. Secondly, PAC's broad applicability across varying pH and temperature conditions common in paper mills ensures consistent treatment performance. The chemical's strong ability to remove color from dye-containing wastewater is also a significant advantage, leading to visually cleaner effluent.

Furthermore, the effectiveness of PAC in clarifying water makes it an invaluable tool for water recycling within paper mills. By treating process water with PAC, mills can remove impurities, allowing the water to be reused in various stages of production, such as pulp washing or paper machine circuits. This not only conserves significant amounts of freshwater but also reduces the volume of wastewater requiring discharge, leading to substantial cost savings and a smaller environmental footprint. The investment in polyaluminium chloride thus supports a more circular economy within the paper industry.
