Polyacrylamide (PAM) is a versatile polymer family with variations tailored for specific industrial applications. Understanding the differences between Non-Ionic Polyacrylamide (NPAM), Anionic Polyacrylamide (APAM), and Cationic Polyacrylamide (CPAM) is crucial for selecting the most effective product. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of PAM products and expertise to guide your choice.

Non-Ionic Polyacrylamide (NPAM) is characterized by its neutral charge. It performs optimally in neutral to mildly acidic conditions and is particularly useful when dealing with wastewater that has suspended solids with low or no charge. Its primary functions include flocculation, thickening, and drag reduction. Industries such as papermaking, mining, and certain wastewater treatments commonly utilize NPAM. The versatility of non-ionic polyacrylamide water treatment applications highlights its broad utility.

Anionic Polyacrylamide (APAM) carries a negative charge due to the presence of carboxylate groups. It is highly effective in flocculating positively charged particles, making it suitable for treating alkaline wastewater, especially those containing positively charged suspended solids or metal ions. APAM is widely used in mining operations, industrial wastewater treatment (e.g., steel plants, electroplating), and water clarification. Its role as a mining industry flocculant is well-established.

Cationic Polyacrylamide (CPAM) possesses a positive charge and is ideal for flocculating negatively charged particles. It is particularly effective in sludge dewatering, where it binds with negatively charged sludge particles, facilitating efficient solid-liquid separation. CPAM is also used in municipal sewage treatment, paper manufacturing (as a retention and drainage aid), and in industries with high organic content wastewater. The effectiveness of sludge dewatering polyacrylamide is largely due to its cationic nature.

The selection of the correct PAM type depends on several factors, including the pH of the water being treated, the charge of the suspended particles, the desired application (flocculation, thickening, etc.), and the presence of other chemicals. For instance, in enhanced oil recovery NPAM applications, the neutral charge can be advantageous as it is less affected by salinity variations in reservoirs compared to charged polymers.
