Polyacrylamide in Wastewater Treatment: Mechanism, Application, and Industry Cases
Polyacrylamide (PAM) is a widely used flocculant in municipal sewage and industrial wastewater treatment. Its mechanism includes: √ Charge Neutralization – Cationic polyacrylamide neutralizes negative particles. √ Bridging Adsorption – Polymer chains form networks that enhance flocculation. √ Flocculation-Sedimentation – Promotes large floc formation for clear water. Application […]

Comprehensive Role of Sodium Acetate as a Carbon Source in Wastewater Treatment Across Different Sectors
Nitrogen removal is a key step in wastewater treatment. Since many influents have low carbon-to-nitrogen (C/N) ratios, external carbon sources are required to achieve effective denitrification. Sodium acetate has become widely used because of its high biodegradability, fast reaction rate, and safety advantages. Role of Sodium Acetate as a Carbon Source 1. Accelerates Denitrification […]
