In the intricate world of chemical procurement, selecting the right grade of a product is fundamental to achieving optimal results. For water treatment professionals, this is especially true when choosing Poly Aluminum Chloride (PAC). With various specifications available, understanding the nuances between different PAC grades is key to ensuring effective water purification and efficient operations. As a dedicated manufacturer and supplier, we guide you through this selection process.

Poly Aluminum Chloride (PAC) is a versatile coagulant used across a spectrum of water treatment applications, from making drinking water potable to treating complex industrial wastewater. The performance of PAC is heavily influenced by its physical and chemical properties, which vary between different grades. When you search to buy PAC, you will encounter different descriptions, often relating to its appearance, production method, and chemical composition.

One of the primary differentiators between PAC grades is their appearance and the production process. PAC is commonly available as a yellow powder, light brown powder, or white powder. The yellow and light brown varieties are typically produced through a spray-drying process and are generally suitable for industrial wastewater treatment, where cost-effectiveness is often a major consideration. Our yellow powder PAC, for instance, is an excellent choice for applications like dyeing wastewater or paper making sizing.

The white powder PAC, on the other hand, is usually manufactured using a roller-drying process or advanced spray-drying techniques that result in a higher purity product with fewer impurities. This higher purity grade is particularly favored for drinking water treatment applications, as it minimizes the introduction of unwanted substances into the potable water supply. If you are sourcing PAC for municipal waterworks or other sensitive applications, specifying white powder PAC with a high Al2O3 content (e.g., 29-30%) is often recommended. We can supply this grade, ensuring compliance with stringent drinking water standards.

Another critical specification is basicity, which, as discussed, affects the charge density and performance. The Al2O3 content, as mentioned, indicates the concentration of active aluminum. When selecting a PAC product, consider your specific water matrix: the type and concentration of pollutants, the pH, temperature, and alkalinity of the water. A knowledgeable supplier can assist in determining the most suitable PAC grade based on these factors. For example, if treating water with high turbidity, a PAC with a higher Al2O3 content might be more effective.

As a reliable manufacturer and supplier, we offer a range of PAC products tailored to different needs. Whether you require a cost-effective yellow PAC for industrial wastewater or a high-purity white PAC for drinking water, we can provide the specifications, competitive pricing, and consistent quality you need. We encourage you to contact us for detailed product information, to request a quote, or to obtain samples. Making an informed choice about your PAC grade is the first step towards achieving superior water treatment outcomes.
