Blufloc AA6518 Anionic Polyacrylamide (APAM) Polymer | High MW PAM Flocculant for Stable Settling & Water Clarification
Product Overview
Blufloc AA6518 is a high molecular weight anionic polyacrylamide (APAM) with a medium anionic charge degree, designed for applications requiring stable floc structure and controlled settling behavior.
As a copolymer of acrylamide and acrylic acid, AA6518 provides effective particle aggregation through polymer bridging while maintaining moderate electrostatic interaction.
Compared with higher charge products, AA6518 offers:
- More stable and uniform floc formation
- Reduced sensitivity to shear forces
- Better performance in systems with gentle mixing
This makes it particularly suitable for gravity sedimentation systems, clarifiers and water treatment processes where floc stability is critical.
Key Advantages
Stable Floc Structure
AA6518 forms consistent and uniform flocs that settle steadily without excessive breakage.
Low Shear Sensitivity
Suitable for systems where mixing intensity is limited or variable.
Controlled Settling Behavior
Provides balanced settling speed, avoiding overly fast or unstable sedimentation.
Improved Water Clarity
Effectively removes fine suspended solids and reduces turbidity.
Flexible Application Range
Works well in municipal, industrial and process water systems.
