Industrial Applications in Bangladesh
Bangladesh Market Context: Used at just 1–5 ppm in every Bangladesh ETP secondary clarifier (APAM) to bridge PAC micro-flocs into fast-settling macro-flocs, and in sludge dewatering presses (CPAM).
- Anionic PAM (APAM): Coagulation-flocculation aid in primary/secondary ETP sedimentation clarifiers
- Cationic PAM (CPAM): Conditioning biological and physico-chemical ETP sludge for filter/screw press dewatering
- Paper retention and drainage aid, ceramic wastewater settling, and sugar juice clarification
