Polyacrylamide for OCC and Recycled Paper Mills | Recycled Paper Retention Aid PAM
OCC and recycled paper mills process large volumes of recovered paper fibers containing ink residues, fillers, adhesives, starch, and suspended contaminants. Compared with virgin pulp systems, recycled paper production usually faces greater challenges in fiber retention, drainage stability, sludge generation, and white water treatment.
Bluwat Blufloc Polyacrylamide is specially developed to improve the efficiency of recycled paper production systems. The polymer enhances fiber retention, accelerates drainage, improves white water clarification, and supports sludge dewatering operations in recycled paper mills.
According to the Blufloc Polyacrylamide Technical Data Sheet, the product is available in anionic, cationic, and nonionic grades with different molecular weights and charge densities suitable for various paper making applications.
Recovered paper fibers are generally shorter and weaker than virgin fibers, increasing the risk of fiber loss. Blufloc PAM helps retain:
- Fine recycled fibers
- Fillers
- Starch additives
- Ink particles
- Functional chemicals
This improves production yield and reduces raw material loss.
Recycled paper systems often contain higher levels of dissolved and colloidal substances that negatively affect drainage. Using PAM helps:
- Accelerate water removal
- Improve machine runnability
- Increase paper machine speed
- Reduce drying energy consumption
The polymer promotes rapid flocculation of suspended solids and contaminants in white water systems. Benefits include:
- Cleaner circulation water
- Better fiber recovery
- Reduced suspended solids
- Improved water recycling efficiency
Recycled paper mills generate significant sludge volumes from flotation, wastewater treatment, and fiber recovery systems. Blufloc PAM improves:
- Sludge thickening
- Filter press performance
- Centrifuge efficiency
- Sludge moisture reduction
This lowers sludge disposal costs and improves plant operation efficiency.
Widely used in old corrugated container paper production systems.
Improves retention and drainage in packaging paper production.
Enhances suspended solids removal and reusable fiber recovery.
Used in sedimentation tanks, DAF systems, and sludge dewatering operations.
Based on the Blufloc TDS:
| Parameter | Specification |
|---|---|
| Appearance | Off-white granular powder |
| Ionic Type | Anionic / Cationic |
| Molecular Weight | 5–25 million |
| Solid Content | Minimum 89% |
| Recommended Working Concentration | 0.1–0.5% |
| Shelf Life | 2 Years |
For best performance:
- Dissolve concentration: 0.1–0.5%
