Nonionic Polyacrylamide Polymer for Paper Factory DAF System White Water Treatment

HENGFENG Nonionic Polyacrylamide (NPAM) powder is specially formulated for Dissolved Air Flotation (DAF) systems in paper manufacturing plants. It provides superior fiber recovery, filler retention, and white water clarification performance. The nonionic polymer structure ensures consistent flocculation regardless of pH variations commonly found in paper mill process water, making it the ideal DAF flocculant for pulp and paper industry wastewater treatment.

Why Nonionic Polymer for Paper Mill DAF Systems

High Fiber Recovery Rate

Effectively recovers 90-95% of cellulose fibers and mineral fillers from white water, reducing raw material loss and lowering production costs. The recovered fiber can be directly returned to the papermaking process.

Superior Filler Retention

Nonionic PAM enhances the retention of calcium carbonate, titanium dioxide, and clay fillers in the DAF float, achieving clarified water with TSS below 30 mg/L suitable for reuse in the paper machine shower system.

Wide pH Compatibility

Performs consistently across pH 3-11, handling acidic rosin-alum sizing systems and alkaline calcium carbonate systems equally well without switching chemical types.

Closed Water Loop Enablement

Enables near-zero discharge paper mill operation by clarifying white water to reuse quality, reducing freshwater consumption by 60-80% and lowering effluent treatment costs.

Paper Mill DAF Applications

Nonionic polyacrylamide is the preferred DAF flocculant for paper mill processes:

White water (circulating water) clarification and fiber recovery
Paper machine save-all DAF unit operation
Deinked pulp (DIP) process water treatment
Coated paper broke recovery system
Board mill and tissue mill water recycling

Dosing Recommendation: Prepare 0.05-0.2% stock solution with clean process water. Inject at 1-3 mg/L before the DAF contact zone. In white water applications, nonionic PAM can be used alone or in combination with bentonite for enhanced clarification. Conduct jar testing with actual white water to determine optimal dosage.

FAQ

Q: Can nonionic PAM replace dual-polymer systems in paper mill DAF?
A: In many white water applications, a single nonionic PAM program can replace dual cationic/anionic programs, simplifying chemical management and reducing operational costs.

Q: Is recovered fiber quality affected by polymer treatment?
A: No, nonionic PAM does not negatively impact fiber quality. Recovered fibers can be directly reintroduced into the stock preparation system without strength or brightness loss.

Q: How does this compare to bentonite-based DAF programs?
A: Nonionic PAM provides faster floc formation and a thicker float blanket. For maximum clarity, combine with bentonite as a co-additive.

Q: Do you support on-site paper mill DAF trials?
A: Yes, our technical team provides jar testing protocols, on-site pilot trials, and full-scale DAF optimization for paper mills. Contact us for details.
