Polyacrylamide for DAF Systems in Paper Mills | Dissolved Air Flotation Flocculant PAM
Dissolved Air Flotation (DAF) systems are widely used in paper mills to separate suspended solids, fibers, fillers, ink particles, and sludge from wastewater and white water systems. Efficient flotation performance is critical for improving water recycling, reducing sludge load, and recovering reusable fibers.
Bluwat Blufloc Polyacrylamide is specially developed for DAF applications in paper manufacturing plants. The polymer rapidly destabilizes colloidal particles and forms large flocs that attach easily to air bubbles, improving flotation efficiency and sludge separation performance.
According to the Blufloc Polyacrylamide Technical Data Sheet, the product is available in anionic, cationic, and nonionic grades with different molecular weights and ionic charge densities suitable for wastewater clarification and paper making applications.
Paper mill white water contains valuable fine fibers and fillers that can be recovered through flotation systems.
Blufloc PAM helps recover:
- Fine cellulose fibers
- Fillers
- Ink particles
- Starch residues
- Coating materials
Recovered materials can be reused in production, reducing raw material loss.
The polymer forms stronger and larger flocs that attach more effectively to microbubbles.
Benefits include:
- Faster flotation speed
- Improved sludge floating layer formation
- Cleaner clarified water
- More stable DAF operation
Efficient DAF treatment reduces:
- Suspended solids
- Turbidity
- Organic contaminants
- COD loading
This improves downstream biological treatment efficiency and overall wastewater quality.
PAM improves sludge concentration and water release during flotation and dewatering.
Advantages include:
- Lower sludge moisture
- Reduced sludge volume
- Improved sludge handling
- Lower transportation and disposal costs
Improves suspended fiber recovery and reusable water clarification.
Widely used in OCC and recycled paper production systems.
Enhances removal of suspended solids before biological treatment.
Improves sludge flotation and dewatering efficiency.
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 DAF performance:
- Recommended concentration: 0.1–0.5%
- Dissolving time: approximately 1 hour
- Agitation speed: 200–400 rpm
Excessive shear should be avoided during preparation to maintain polymer chain structure and flotation efficiency.
Typical dosing points include:
- DAF inlet pipe
- Rapid mixing tank
- Coagulation tank
- White water flotation unit
Laboratory flotation testing is recommended before industrial application.
