Nonionic Polyacrylamide Flocculant
Nonionic polyacrylamide (NPAM) flocculant suitable for clarification of weakly acidic and neutral wastewater where ionic flocculants are incompatible. Flocculation occurs purely by polymer bridging without charge effects, making it versatile across varying conductivity conditions. Commonly used in mining, ceramics, and coal washing.
