In the realm of water treatment, the performance of Polyaluminium Chloride (PAC) is significantly influenced by its chemical characteristics, with basicity being a particularly critical parameter. For procurement managers and chemical engineers looking to buy PAC, understanding basicity is key to selecting the most effective product for their specific application. As a dedicated manufacturer and supplier of PAC, we aim to demystify this important metric.

Polyaluminium Chloride basicity refers to the concentration of hydroxyl groups relative to aluminium ions in the molecule. It is typically expressed as a percentage. A higher basicity generally indicates a higher degree of polymerization and a greater proportion of the positively charged polymeric species responsible for charge neutralization and bridging. In essence, a higher basicity can lead to more efficient coagulation and flocculation at lower dosage rates.

The typical range for PAC basicity often falls between 40% and 90%, with different applications benefiting from specific ranges. For instance, products with higher basicity might be preferred for demanding wastewater treatment scenarios requiring rapid contaminant removal. Conversely, products with moderate basicity can be equally effective in other applications, offering a balance of performance and cost. When you purchase PAC, you will find specifications detailing this parameter, alongside Aluminium Oxide (Al2O3) content and pH.

Choosing the right basicity is crucial for optimizing your water treatment processes. A PAC with inappropriate basicity for your water conditions might require higher doses to achieve the desired outcome, potentially increasing costs and generating more sludge. As a leading supplier, we offer a range of PAC products with varying basicity levels, allowing our clients to select the most suitable option. We encourage our customers to consult with our technical team to determine the ideal PAC basicity for their specific water treatment challenges, ensuring maximum efficiency and cost-effectiveness from their purchase.
