Anionic Polyacrylamide Flocculant
CAS Number: 9003-05-8
High molecular weight anionic polyacrylamide (APAM) flocculant designed for clarification of municipal and industrial wastewater. Operates via charge neutralization and bridging to agglomerate suspended solids into settleable flocs. Effective across a wide pH range with low dosage requirements.
