Introduction to Original Praestol 2640
Praestol 2640 is medium-high hydrolysis anionic PAM with molecular weight up to 16 million, featuring wide pH tolerance range (6–13). Its long polymer chains form strong bridging effect to capture fine suspended solids, generating large, shear-resistant flocs with rapid sedimentation.
Typical application scenarios:
- Mine mineral processing, tailings sedimentation & tailings dry stacking
- Quarry sand washing slurry & recycled water clarification
- Alumina refining & red mud separation
- Municipal & industrial wastewater clarification, sludge thickening
- Paper making & chemical suspended liquid treatment
Why our anionic polyacrylamide (PAM) can replace Praestol 2640:
- Precisely matches its molecular weight, degree of anionic hydrolysis, and charge density.
- Compatible with most operating conditions, including mine tailings, sand washing, and municipal wastewater treatment.
- Denseer flocs improve dewatering and water recycling efficiency.
- No risk of stockouts for large-scale polyacrylamide (PAM) production lines.
- pH tolerance range of 6-13, strong anti-interference ability.
