What’s the difference between polyacrylamide (anionic) and (cationic)

     There is a big difference between polyacrylamide anions and cations. They are both polymer flocculants. Anions and cations are two different models.

1.Anionic polyacrylamide is mainly used for flocculation, sedimentation, sedimentation and clarification treatment of various industrial wastewaters, such as sand washing wastewater, coal washing wastewater, electroplating plant wastewater, steel plant wastewater and other wastewater treatment. They are due to the fact that their molecular chains contain a certain number of polar groups, which can adsorb solid particles suspended in water, bridge them between particles, or aggregate particles to form large flocs through charge neutralization. Therefore, it can accelerate the settling of particles in the suspension and accelerate the clarification of the solution.

2. Cationic polyacrylamide is mainly used in industrial solid-liquid separation. Cationic polyacrylamide is suitable for sludge dehydration and JI sewage flocculation. They use electrostatic action to adsorb multiple negatively charged suspended particles in the sewage to their chains, causing the dispersed and smaller suspended particles to agglomerate together. Achieve the purpose of solid-liquid separation.
