In the realm of water treatment, the effectiveness of Polyaluminium Chloride (PAC) is often closely tied to its basicity. For procurement managers and R&D scientists seeking to optimize their water purification processes, understanding PAC basicity is a key differentiator. As a leading manufacturer, we aim to demystify this crucial parameter.

Basicity in PAC refers to the proportion of hydroxyl groups (OH-) relative to aluminum ions within the polymer chain. It's essentially a measure of the degree of polymerization and the formation of complex hydroxy-aluminum species. Products are typically characterized by a basicity ranging from 40% to over 90%.

Why is basicity so important? Higher basicity generally indicates a more stable and highly polymerized PAC. These products tend to have a greater positive charge density, which enhances their ability to neutralize and aggregate negatively charged suspended particles and colloids in water. This leads to more efficient flocculation, faster settling times, and improved turbidity removal.

For instance, PAC with a higher basicity (e.g., 70-90%) is often preferred for applications requiring superior performance, such as treating low-temperature or low-turbidity raw water. These advanced PAC products can lead to larger, denser flocs that settle more rapidly, reducing the burden on subsequent filtration stages and minimizing the volume of sludge produced. This efficiency can translate into lower chemical consumption and reduced operational costs.

Conversely, PAC with lower basicity might be suitable for less demanding applications or where cost is the primary driver. However, it's crucial to match the PAC's basicity to the specific characteristics of the water being treated. Factors like pH, temperature, and the nature of the contaminants all play a role in determining the optimal PAC product.

As a manufacturer, we offer a range of PAC products with varying basicity levels to cater to diverse water treatment needs. When you are ready to buy PAC, consulting with your supplier about the required basicity for your specific application is highly recommended. We, as a reliable PAC supplier in China, are equipped to provide technical guidance to help you select the most effective product. Invest in understanding basicity to ensure you purchase the most efficient coagulant for your water treatment challenges.
