For procurement managers, R&D scientists, and formulation chemists in the water treatment industry, selecting the right Polyaluminium Chloride (PAC) is critical for optimal performance and cost-effectiveness. As a leading Polyaluminium Chloride manufacturer in China, we understand that precise specifications are key to ensuring that PAC meets the demands of diverse applications. This guide outlines the essential parameters you should consider when you look to buy Polyaluminium Chloride.

Understanding Core PAC Specifications

Polyaluminium Chloride is not a single chemical compound but a family of inorganic polymers. Its effectiveness is determined by several key chemical and physical properties, which are detailed in product specifications. Understanding these will help you choose the most suitable product for your needs:

• Aluminum Oxide (Al2O3) Content: This is a fundamental measure of the aluminum content in the PAC. Higher Al2O3 content generally indicates a more concentrated product and can influence its coagulating power. For example, drinking grade PAC often specifies a minimum Al2O3 percentage.
• Basicity: This is a crucial specification that defines the degree of polymerization and the ratio of hydroxyl groups to aluminum atoms. Basicity is usually expressed as a percentage. A higher basicity (e.g., 45%-55% for some drinking grades) generally means lower residual aluminum and better performance in certain water conditions. The specific basicity required depends on the water characteristics being treated.
• Appearance: PAC is typically available as a white or yellowish powder or a liquid. The appearance can indicate its purity and intended application. For instance, drinking grade PAC is often a white powder.
• Water Insolubles: This specification indicates the amount of insoluble matter present in the PAC. Lower percentages of water insolubles are preferred, especially for drinking water applications, as they contribute to cleaner treatment processes and less residue. A typical specification for drinking grade PAC is a maximum of 0.1% water insoluble.
• pH Value: The pH of a PAC solution provides insight into its acidity or alkalinity. Most PAC products have a slightly acidic pH (e.g., 3.5-5.0), which is beneficial for coagulation in a wide range of water pH conditions.

Importance of Certifications and Grade

When you purchase Polyaluminium Chloride for drinking water treatment, look for products with relevant certifications such as WQA, REACH, NSF, ISO, and SGS. These certifications are a testament to the product's quality, safety, and compliance with international standards. For industrial applications, specific grades might be tailored for efficiency in decolorization, de-oiling, or other processes.
