The selection of the appropriate grade of Polyaluminum Chloride (PAC) is critical for achieving optimal results in various industrial and municipal applications. As a prominent manufacturer and supplier of PAC in China, we understand that B2B buyers, including R&D scientists and procurement managers, need clear guidance to make informed decisions. This article will help you differentiate between industrial and drinking water grades of PAC and understand why sourcing from a reputable manufacturer like us is essential.

Polyaluminum Chloride (PAC) is a versatile inorganic polymer coagulant used widely in water purification and wastewater treatment. The primary distinction between grades lies in their purity levels and intended applications, directly impacting their physical appearance and acceptable impurity limits. For those looking to buy Polyaluminum Chloride for drinking water treatment, our drinking grade PAC is manufactured under stringent quality controls, ensuring it meets the rigorous standards for potable water, such as those outlined by WQA and REACH certifications, and has very low levels of heavy metals like arsenic and lead.

Industrial grade Polyaluminum Chloride, on the other hand, is formulated for applications where the highest purity is not the absolute priority, but efficacy in specific industrial processes is key. This includes its use in papermaking, textile dyeing, and general industrial wastewater treatment. While still a high-performance chemical, industrial grade PAC may have slightly higher allowable limits for certain impurities compared to its drinking water counterpart. However, it remains a highly effective and cost-efficient solution for these applications. Purchasing industrial PAC from a trusted manufacturer ensures you receive a product optimized for performance in your sector.

When you consider purchasing PAC, especially from a China-based supplier, examining the technical specifications is paramount. For drinking water applications, key parameters include a minimum 28-30% Al2O3 content, low water-insoluble matter (≤ 1.0%), and a specific pH range. Our yellow drinking grade PAC is specifically designed for these demanding applications. For industrial uses, while similar Al2O3 content is maintained, slight variations in basicity or water insolubles might be acceptable depending on the specific industrial process. We offer various industrial grades, including powders and granules in brown or dark brown colors, each tailored for specific performance needs.

Choosing the right PAC supplier is as important as choosing the right grade. As a manufacturer with over 30 years of experience, we guarantee product consistency, reliable supply, and competitive pricing. Whether you need to buy PAC for municipal water treatment, industrial effluent management, or specialized applications like precision casting (where white PAC is often preferred), our team can provide the necessary technical support and product recommendations. Our commitment to quality and customer service makes us a premier PAC supplier for global markets.

In conclusion, understanding the specific requirements of your application is key to selecting the correct grade of Polyaluminum Chloride. By partnering with a leading China manufacturer like us, you can confidently purchase either industrial or drinking water grade PAC, assured of its quality, performance, and cost-effectiveness.
