Polyacrylamide (PAM) is a highly versatile polymer with a broad range of applications, but choosing the correct type is paramount for achieving optimal results. The three main categories—anionic, cationic, and nonionic polyacrylamide—each possess distinct properties that make them suitable for different industrial processes. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range to meet diverse needs and provides guidance for selection.

Anionic Polyacrylamide (APAM): APAM carries a negative charge and is most effective in flocculating positively charged colloids. It excels in applications involving suspended solids with positive surface charges, such as in the treatment of industrial wastewater from steel plants, electroplating facilities, and coal washing operations. APAM is also used in mineral processing for thickening and clarifying, and in the papermaking industry as a retention aid. Its effectiveness in water treatment with high organic colloid content is a key advantage.

Cationic Polyacrylamide (CPAM): CPAM possesses a positive charge and is the preferred choice for treating negatively charged substances, most notably in sludge dewatering. Municipal sewage sludge, as well as sludge from industries like food processing and paper manufacturing, typically has a strong negative charge. CPAM effectively neutralizes these charges, leading to superior flocculation and a drier sludge cake. Its application in the dairy industry for sludge treatment is also significant.

Nonionic Polyacrylamide (NPAM): NPAM has a neutral charge, making its performance less dependent on pH and salt concentration. This characteristic makes it suitable for a variety of applications, including papermaking as a retention and filter aid, and in oilfields where conditions can be variable. It performs well in acidic wastewater treatment where the efficacy of ionic flocculants might be compromised.

When selecting polyacrylamide, industrial buyers should consider the nature of the material being treated (e.g., charge of particles, pH, presence of salts), the desired outcome (e.g., clarification, dewatering, viscosity modification), and the specific industry context.
