Polyaluminium Chloride (PAC) is a complex inorganic polymer, and its effectiveness in water treatment is profoundly influenced by its chemical composition, particularly its basicity. Understanding this parameter is key to optimizing water treatment processes. NINGBO INNO PHARMCHEM CO.,LTD. offers insights into how basicity dictates PAC's performance.

Basicity, in the context of PAC, refers to the ratio of hydroxyl ions (OH-) to aluminum ions (Al3+) within the polymer structure. It is often expressed as a percentage. This ratio dictates the degree of polymerization and the charge density of the PAC molecules. Generally, higher basicity implies a greater degree of polymerization and a more complex, higher molecular weight polymer.

The importance of basicity lies in its direct impact on PAC's coagulation and flocculation efficiency. Products with lower basicity (e.g., 40-60%) tend to be more acidic and possess a higher concentration of aluminum ions. These types of PAC are often effective at neutralizing the negative charges of colloidal particles and are good at reducing turbidity. They can perform well in a broad pH range and are often favored for their ability to form robust flocs.

Conversely, PAC products with higher basicity (e.g., 60-80%) have a higher degree of polymerization and a greater proportion of hydroxyl groups. These higher basicity PACs can be more efficient in forming larger, more stable flocs. They often require lower dosages for effective treatment and can result in lower residual aluminum levels in the treated water, which is a critical factor for drinking water applications. The higher polymeric content also means they can be more effective in removing specific types of contaminants and may have a reduced impact on the pH of the water being treated.

The selection of PAC with the appropriate basicity is crucial and depends heavily on the specific water quality characteristics being addressed. Factors such as raw water turbidity, pH, temperature, and the nature of contaminants all influence which basicity level will yield the optimal results. For instance, drinking water treatment often benefits from higher basicity PAC due to its enhanced performance in clarity and lower residual aluminum. Industrial wastewater, on the other hand, might find lower or mid-basicity PAC more suitable depending on the specific pollutants present.

NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing a range of PAC products with carefully controlled basicity levels to meet diverse water treatment needs. Understanding the basicity of Poly Aluminium Chloride allows users to select the most effective and economical coagulant for their application. Whether the goal is high turbidity removal or efficient phosphorus reduction, the right basicity is key.

In summary, basicity is not just a chemical specification; it is a performance indicator for Poly Aluminium Chloride. By understanding and selecting PAC based on its basicity, water treatment professionals can significantly enhance the efficiency, cost-effectiveness, and quality of their water purification processes.
