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

Nonionic polyacrylamide is the preferred DAF flocculant for paper mill processes:
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.
Jiangsu Hengfeng Fine Chemical Co., Ltd. is a leading polyacrylamide manufacturer with 25 years of industry experience, covering 125 acres with 50,000 tons/year powder and 50,000 tons/year emulsion production capacity. Our DCS-controlled production lines and comprehensive QA system ensure consistent quality. We export to 60+ countries and provide full technical support including on-site paper mill DAF optimization.
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.
