Polyaluminium Chloride (PAC) is a cornerstone chemical in modern water treatment and various industrial processes. Its efficacy as a coagulant and flocculant makes it indispensable for purifying water and enhancing the performance of numerous applications. This guide, brought to you by NINGBO INNO PHARMCHEM CO., LTD., explores the fundamental aspects of PAC, including its properties, different grades, and the advantages of sourcing from China.

PAC is an inorganic polymer salt synthesized from aluminum chloride and other aluminum compounds. Its primary function in water treatment is to neutralize the negative charges of colloidal particles suspended in water, allowing them to aggregate into larger flocs. These flocs are then easily removed through sedimentation or filtration. The effectiveness of PAC lies in its high charge density and ability to form voluminous flocs, which entrap impurities efficiently.

A key aspect differentiating PAC products is their color, typically ranging from yellow to pale yellow and white. The yellow varieties are often formulated for general industrial wastewater treatment, where high levels of suspended solids and organic matter need to be removed. In contrast, White Polyaluminium Chloride is produced through a more refined process, resulting in significantly lower levels of impurities like iron. This makes White PAC the preferred choice for sensitive applications such as drinking water purification and the treatment of high-purity industrial water. If you intend to buy Polyaluminium Chloride for drinking water, specifying the white grade is essential.

When looking to procure PAC, understanding the specifications is vital. Parameters such as aluminum oxide content (Al2O3%), basicity, and water-insoluble matter directly influence performance. A higher Al2O3 content generally indicates a stronger coagulant, while basicity affects its performance across various pH levels. Minimizing water-insoluble matter is crucial, especially for applications demanding high purity. Sourcing from a reputable Polyaluminium Chloride manufacturer ensures these specifications are consistently met.

China has emerged as a global hub for chemical manufacturing, offering competitive pricing and large-scale production capabilities. For businesses seeking to purchase PAC, sourcing from a reliable Chinese supplier like NINGBO INNO PHARMCHEM CO., LTD. provides significant advantages.
