Tips for Dissolving and Dosing PAC/PAM

Summary: Flocculant solution strength, maturation time, dosing-point selection and common preparation mistakes.
Solution Strength
- PAC: 5-10% solution
- PAM: 0.1-0.3%, matured 30-60 min at low speed
Dosing Tips
Dose at turbulent sections for mixing without shear destroying flocs; never convey PAM through high-speed centrifugal pumps.
Common Mistakes
Over-concentrated solutions clog pump and lines; insufficient maturation wastes chemical; mixing PAM and PAC together inactivates them — dose separately.
