Selecting the correct water treatment chemical is paramount for ensuring the quality and safety of water, whether it's for municipal supply or industrial processes. Among the most widely used and effective coagulants is Polyaluminium Chloride (PAC). As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role PAC plays and offers insights into choosing the optimal grade for your specific requirements.

Polyaluminium Chloride, commonly known as PAC, is an inorganic polymer coagulant known for its high efficiency, broad applicability, and cost-effectiveness. It functions by neutralizing the negative charges on suspended particles in water, allowing them to aggregate into larger flocs, which can then be easily removed through sedimentation or filtration. This process is vital for removing turbidity, color, and organic matter.

When considering a purchase, several key specifications for PAC are important to evaluate. The most common grades you'll encounter when looking to buy are based on their aluminum oxide (Al2O3) content and basicity. A 30% PAC, for instance, indicates the approximate percentage of aluminum oxide, which is a primary indicator of its coagulant strength. Higher Al2O3 content generally means higher efficiency, though application-specific testing is always recommended.

Basicity refers to the degree of polymerization of the aluminum species in PAC. A higher basicity typically leads to better performance at lower dosages and a wider effective pH range. For many industrial and municipal water treatment applications, including drinking water treatment and wastewater treatment, PAC grades with basicity ranging from 40% to 90% are commonly used and offered by reputable suppliers.

The physical form of PAC also matters. It is available in both liquid and solid (powder or granular) forms. Solid PAC, often produced via spray drying, is convenient for storage and transportation, but requires dilution before use. Liquid PAC is ready-to-use, which can simplify dosing systems for some facilities. NINGBO INNO PHARMCHEM CO.,LTD. provides both forms to cater to diverse operational needs, ensuring you can purchase the most suitable product for your plant.

When researching suppliers, it’s crucial to look for manufacturers with established quality control processes, such as ISO certification, and a proven track record. Understanding the technical support offered by a supplier can also be invaluable. For example, NINGBO INNO PHARMCHEM CO.,LTD. can assist in determining the optimal dosage of PAC for your raw water through jar testing, ensuring you achieve the best possible treatment results and cost efficiency. This expert guidance is a significant advantage when you purchase bulk quantities.

The application of PAC is extensive. It is widely utilized in the purification of drinking water, treating domestic sewage, and managing industrial wastewater from sectors like textiles, papermaking, and mining. Its effectiveness in removing suspended solids, heavy metals, and color makes it indispensable. For those seeking to buy PAC for these critical applications, partnering with a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. guarantees consistent quality and dependable supply.

In conclusion, when you need to purchase Polyaluminium Chloride, carefully consider the Al2O3 content, basicity, and physical form, and most importantly, partner with a trusted manufacturer and supplier who can provide technical expertise and consistent product quality. NINGBO INNO PHARMCHEM CO.,LTD. is your go-to source for high-performance PAC, ensuring your water treatment processes are both efficient and compliant.
