Polyacrylamide Coagulant Aid for Kraft Paper Wastewater Treatment
Kraft paper manufacturing generates wastewater containing high concentrations of suspended fibers, lignin residues, starch, fillers, inks, and organic contaminants. These wastewaters often exhibit high COD, dark color, turbidity, and sludge loads that require efficient treatment before discharge or recycling.
Bluwat Blufloc Polyacrylamide is specially developed as a coagulant aid for kraft paper wastewater clarification systems. The polymer rapidly aggregates suspended particles into large and dense flocs, improving sedimentation, flotation, and sludge dewatering efficiency.
According to the Blufloc Polyacrylamide Technical Data Sheet, the product is available in anionic, cationic, and nonionic forms with different molecular weights and ionic charge densities suitable for industrial wastewater treatment and paper making applications.
Kraft paper wastewater contains large amounts of fibers and colloidal solids that are difficult to settle naturally. Blufloc PAM helps:
- Aggregate fine particles rapidly
- Form stronger sludge flocs
- Accelerate sedimentation
- Produce clearer supernatant water
This significantly improves clarification performance.
The polymer improves removal of:
- Fiber residues, Organic suspended solids
- Ink particles, Starch residues, Coating materials
This helps reduce COD loading before biological treatment or discharge.
Blufloc PAM is widely used together with PAC, Aluminum sulfate, Ferric sulfate, and DAF systems. The polymer strengthens floc formation and improves flotation and settling performance.
PAM improves sludge structure and promotes water release during mechanical dewatering. Advantages include:
- Lower sludge moisture & Reduced sludge volume
- Improved filter press performance
- Lower sludge disposal costs
Used for suspended solids removal before biological treatment systems.
Improves flotation efficiency and sludge separation.
Reduces solids loading entering aerobic or anaerobic systems.
Enhances sludge treatment efficiency in paper mill wastewater plants.
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 optimal wastewater clarification performance:
- Recommended concentration: 0.1–0.5%
- Dissolving time: approximately 1 hour
- Agitation speed: 200–400 rpm
Avoid excessive shear during preparation to maintain polymer chain structure and flocculation efficiency.
Typical dosing points include: Rapid mixing tank, Flocculation tank, DAF inlet, Sedimentation tank, and Sludge dewatering system. Laboratory jar testing is recommended before industrial application.
