Polyacrylamide (PAM) is a highly effective polymer utilized across numerous industries, primarily for its flocculation and water treatment capabilities. However, not all PAMs are created equal. Understanding the differences between anionic, cationic, and non-ionic PAM is crucial for selecting the most appropriate product for a given application. NINGBO INNO PHARMCHEM CO., LTD. offers a comprehensive selection of PAM types, backed by expert guidance to help you make the best choice.

Anionic Polyacrylamide (APAM) is characterized by its negatively charged functional groups. It is particularly effective in treating neutral to alkaline wastewater that contains positively charged suspended particles and a high concentration of suspended solids. APAM is widely used in applications such as treating wastewater from iron and steel plants, electroplating facilities, and coal washing operations. Its ability to effectively flocculate and sediment these particles makes it an excellent choice for industrial effluent treatment. When considering the purchase of PAM, the hydrolyzing degree and effective pH value are key specifications for APAM.

Cationic Polyacrylamide (CPAM), conversely, possesses positively charged functional groups. This makes it exceptionally suitable for dewatering sludge, especially municipal and industrial sludge with high organic content and negative charges. CPAM's strong bridging capabilities help in agglomerating sludge particles, significantly improving dewatering efficiency and reducing the volume of sludge that needs disposal. It is also widely used in wastewater treatment in industries like dyeing, paper manufacturing, and food processing, particularly where sludge thickening and dewatering are primary concerns. The ion degree is a critical parameter for CPAM.

Non-ionic Polyacrylamide (NPAM) has a neutral charge. While it may not have the same charge neutralization capabilities as its ionic counterparts, it is highly effective as a flocculant, dispersant, and thickening agent, especially in acidic conditions. NPAM is often used in conjunction with inorganic flocculants to enhance water purification, particularly for tap water. Its excellent solubility and thickening properties also find use in industries like textiles and oil recovery. The molecular weight and ion content are important factors when selecting NPAM.
