Anionic Polyacrylamide Flocculant Powder Polymer PAM For Water Treatment

Polyacrylamide products are mainly divided into anionic, cationic and non-ionic types according to ion types. The most applications are in oil fields and water treatment, followed by papermaking and other industrial uses. Anionic polyacrylamide is a negatively charged polymer product. The main indicators are molecular weight and degree of hydrolysis. Generally, the molecular weight ranges from several million to over 20 million. Cationic polyacrylamide is a positively charged polymer. The main indicators are ionicity and molecular weight. The ion degree is generally 5-80%, and the molecular weight is mostly within 12 million.

In the field of sewage treatment, the difference between anionic polyacrylamide and cationic polyacrylamide lies in the different uses. Cationic polyacrylamide is suitable for sludge dehydration, organic sewage flocculation, high-toxic sewage treatment, decolorization, deodorization and other functions. Many negatively charged suspended particles are adsorbed on the chain, so that the dispersed and smaller suspended particles are agglomerated together to achieve the purpose of solid-liquid separation. Anionic polyacrylamide is suitable for industrial sewage flocculation and sludge dewatering. Negatively charged groups usually consist of weakly acidic carboxylic acid groups and strongly acidic sulfonic acid groups. The charged colloidal particles form bridging adsorption, which makes the suspended particles in the sewage coagulate rapidly. At the same time, the product has thickening and drag reduction effects.
