The Role of Polyacrylamide in Urban Wastewater Treatment
Polyacrylamide is a highly effective flocculant used to remove suspended solids, organic compounds, and other pollutants from wastewater. For urban wastewater treatment, cationic polyacrylamide (CPAM) is the most commonly used type due to its ability to neutralize negatively charged particles in the water.
- Key Applications of Cationic Polyacrylamide:
- Flocculation and Sedimentation: CPAM neutralizes negatively charged particles in sewage, forming larger flocs that settle easily.
- Sludge Dewatering: CPAM is essential for separating water from sludge, reducing sludge volume, and improving filtration efficiency.
- Cost-Effective Treatment: When used in combination with inorganic coagulants like polyaluminum chloride (PAC), CPAM enhances treatment efficiency and reduces operational costs.
