NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing a comprehensive range of polyacrylamide (PAM) flocculants, essential chemicals for various water treatment and industrial processes. Understanding the distinctions between Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), and Non-ionic Polyacrylamide (NPAM) is key to selecting the most effective product for a specific application.

Polyacrylamide is a linear polymer that works by bridging particles in a liquid medium, thereby facilitating their separation. The primary difference between APAM, CPAM, and NPAM lies in their electrical charge. APAM, carrying a negative charge, is highly effective in flocculating positively charged suspended solids and is widely used in industrial wastewater treatment, papermaking, and mineral processing. Its strong adsorption and bridging capabilities make it ideal for applications where high turbidity or specific types of contaminants are present.

CPAM, on the other hand, carries a positive charge. This makes it particularly effective for treating wastewater with high organic content and for sludge dewatering, where it binds to negatively charged organic matter and sludge particles. CPAM is often the flocculant of choice for municipal sewage treatment and dewatering of sludges from industries like food processing and tanneries. Its ability to achieve rapid dewatering is a significant advantage.

NPAM, having a neutral charge, is less sensitive to changes in pH and salt concentration. It is often used in applications where the wastewater characteristics are variable or acidic. NPAM finds use in textile processing, as a thickener, and in certain water treatment scenarios where specific interactions are not dependent on charge. While it can be used for flocculation, its effectiveness is sometimes enhanced when paired with inorganic coagulants.

NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity grades of all three types of polyacrylamide. The choice between APAM, CPAM, and NPAM often depends on the specific nature of the wastewater or slurry being treated, including its pH, ionic composition, and the type of contaminants present. Our technical team can provide expert guidance to help clients determine the most efficient and cost-effective polyacrylamide flocculant for their unique requirements. Investing in the right PAM product ensures optimal performance, leading to cleaner water and more efficient industrial processes.
