Polyacrylamide for Iron Ore Wastewater Treatment

Polyacrylamide (PAM) is widely used in wastewater treatment, including iron ore wastewater treatment. It functions as a coagulant aid or flocculant, which helps in the separation of suspended particles and contaminants from water.Here are some key points about using polyacrylamide for iron ore wastewater treatment:1. **Types of PAM**: There are two main types of PAM used in wastewater treatment: anionic (negatively charged) and cationic (positively charged). The choice between anionic and cationic PAM depends on the characteristics of the wastewater and the nature of the particles to be removed.2. **Mechanism of Action**: When added to wastewater, PAM molecules attract and bind to the particles present in the water, forming larger aggregates or flocs. These flocs then settle more easily due to gravity, allowing for effective removal through sedimentation or filtration processes.3. **Dosage**: The dosage of PAM required can vary significantly based on factors such as the concentration o…
