Common Problems in Coal Mine Wastewater Treatment 1. Water becomes more turbid after treatment? Usually caused by incorrect
PAM ion type or dosage. 2. Slow sedimentation? Often due to low molecular weight PAM or high sludge concentration. 3. Weak or broken flocs? High molecular weight PAM is needed, or mixing speed is too fast.
How to Choose the Right PAM for Coal Mine Wastewater Condition 1: High turbidity & high coal content Recommended:
Anionic PAM, MW 12–16 million. Condition 2: Very fine particles, difficult to settle Recommended: High molecular weight anionic PAM, MW 15–19 million. Condition 3: Used together with PAC or PFS Recommended: Medium molecular weight PAM for better synergy. Condition 4: Need very clear recycled water Recommended: Ultra-high molecular weight PAM, MW 18–20 million.
