NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing a range of high-purity polyacrylamide (PAM) products, tailored to meet diverse industrial requirements. Understanding the fundamental differences between anionic, cationic, and nonionic polyacrylamide is crucial for selecting the most effective product for a specific application. Each type possesses unique characteristics derived from its chemical structure and ionic charge, dictating its performance in various processes.

Anionic Polyacrylamide (APAM) is characterized by its negative charge. It excels in flocculating negatively charged colloids and is widely used in municipal sewage treatment, industrial wastewater treatment (such as from coal washing, mineral processing, and steel industries), and for enhanced oil recovery. The anionic polyacrylamide applications are particularly effective in systems with high organic colloid content where its charge neutralization properties are most beneficial.

Cationic Polyacrylamide (CPAM), conversely, carries a positive charge. This makes it highly efficient for sludge dewatering, as it effectively binds to negatively charged sludge particles. It is a preferred choice for treating wastewater from industries like alcohol factories, paper mills, and tanneries, where effective solids removal is paramount. The fast dissolution rate and high dehydration efficiency of CPAM are key advantages.

Nonionic Polyacrylamide (NPAM), lacking a significant charge, is less affected by pH variations and salt content. It is a versatile flocculant effective in various sewage treatment scenarios, including oily wastewater. While its flocculation strength might be comparable or sometimes less than ionic types in certain conditions, its stability across different water chemistries makes it a valuable option. NINGBO INNO PHARMCHEM CO.,LTD. offers these different types of polyacrylamide, enabling clients to choose the optimal solution based on their specific process requirements, ensuring superior performance and efficiency.
