For procurement professionals and chemical engineers tasked with water treatment, a thorough understanding of Polyaluminium Chloride (PAC) technical specifications is fundamental. PAC, an inorganic polymer coagulant, is valued for its efficiency in clarifying water by removing suspended solids, turbidity, and organic matter. However, its optimal performance hinges on its specific properties, namely Al2O3 content, basicity, and pH. Sourcing the correct grade of PAC from a reliable PAC manufacturer ensures consistent results and cost-effectiveness.

The Al2O3 content is a primary indicator of the aluminum concentration within the PAC product. Generally, a higher Al2O3 content suggests a more concentrated source of active coagulant. Different industrial applications may require varying levels of Al2O3. For instance, applications demanding robust coagulation might benefit from PAC with a higher Al2O3 percentage. When you buy Polyaluminium Chloride powder, always check the Al2O3 specification, as it directly impacts dosage calculations and treatment efficacy.

Basicity is another critical parameter, referring to the degree of polymerization of the aluminum species. It is typically expressed as a percentage and indicates the ratio of hydroxyl groups to aluminum atoms. A higher basicity usually means a more highly polymerized form of PAC, which leads to more efficient charge neutralization and floc formation. Products with higher basicity often require lower dosages and produce less sludge. This is a key factor when evaluating the PAC for wastewater treatment price, as a more efficient product can lead to greater overall savings.

The pH of PAC solutions is also an important consideration. Most PAC products have an acidic pH, typically ranging from 3.5 to 5.0 for a 1% solution. This inherent acidity can sometimes help in adjusting the pH of the water being treated, reducing the need for additional acid or alkali. However, it's crucial to understand how the PAC's pH will interact with the target water's pH to achieve optimal coagulation. Understanding these nuances is key to effective sourcing from a competent industrial grade PAC supplier in China.

When looking to procure PAC, it’s vital to engage with suppliers who provide detailed Certificates of Analysis (CoA) that clearly outline these technical specifications. These documents serve as a guarantee of product quality and consistency. Furthermore, a good chemical coagulant manufacturer will offer technical support to help clients select the most appropriate PAC grade based on their specific water quality parameters and treatment objectives.

In summary, mastering the technical specifications of Polyaluminium Chloride – its Al2O3 content, basicity, and pH – is essential for any organization involved in water treatment. By paying close attention to these details and sourcing from reputable suppliers, you can ensure you purchase Polyaluminium Chloride that delivers optimal performance, efficiency, and economic benefits for your industrial operations. Partnering with a knowledgeable PAC manufacturer will greatly simplify this process.
