As a trusted industrial polyacrylamide supplier and cationic polyacrylamide exporter, we demonstrate how our water treatment flocculant achieved superior clarification results while reducing operational costs. Discover why global PAM suppliers and water treatment professionals choose our tailored solutions for sustainable wastewater management.

Municipal Water Treatment Challenges

Municipal wastewater contains complex contaminants including organic matter, heavy metals, and suspended solids. Traditional treatment methods often struggle with:

• High turbidity levels exceeding 50 NTU
• Slow sedimentation rates (2-4 hours per cycle)
• Chemical oxygen demand (COD) above 300mg/L
• Excessive sludge volume (30-40% moisture content)

Technical Performance of Cationic Polyacrylamide

Our CPAM series demonstrates superior performance metrics:

Case Study: Tianjin Water Treatment Plant

A municipal plant processing 50,000m³/day achieved:

1. 85% reduction in turbidity (from 45 NTU to 6.5 NTU)
2. 40% lower sludge volume compared to conventional alum treatment
3. 25% reduction in overall chemical costs
4. Compliance with GB 18918-2002 discharge standards
