Nonionic Polyacrylamide DAF System Flocculant for Paper Factory Deinking Effluent Treatment

HENGFENG Nonionic Polyacrylamide Polymer Powder is engineered for Dissolved Air Flotation (DAF) systems treating deinking process effluent in paper recycling factories. The nonionic polymer effectively removes printing ink particles, stickies, and colloidal contaminants from deinking water, ensuring efficient ink flotation and producing high-quality recycled pulp for paper production. Its pH-independent flocculation mechanism makes it ideal for the variable chemical environment of deinking circuits.

DAF Performance in Paper Deinking Applications

Effective Ink Particle Removal

Nonionic PAM efficiently flocculates and floats dispersed printing ink particles (10-100 um) in the deinking DAF unit, achieving 90-98% ink removal efficiency and producing cleaner recycled pulp.

Stickies and Contaminant Control

Effectively aggregates and removes hot-melt adhesives, pressure-sensitive adhesives, coating binders, and other sticky contaminants that cause paper machine deposits and sheet defects.

Chemical Compatibility

Works synergistically with deinking chemicals including sodium hydroxide, sodium silicate, hydrogen peroxide, and fatty acid collectors without interference or performance degradation.

COD and BOD Reduction

Reduces COD by 60-80% and BOD by 50-70% in deinking effluent, helping paper mills meet increasingly stringent wastewater discharge regulations and reducing surcharge costs.

Paper Factory DAF Applications

This nonionic polyacrylamide is proven effective in paper recycling and deinking DAF systems:

Mixed office waste (MOW) deinking flotation
Old newsprint (ONP) deinking DAF circuits
Old corrugated containers (OCC) process water treatment
Facial tissue and hygiene paper deinking systems
Tissue mill and packaging mill wastewater treatment

Dosing Recommendation: Prepare 0.05-0.2% polymer solution using an automatic make-down unit. Apply at 2-5 mg/L in the DAF feed line after deinking chemicals addition. For heavily printed wastepaper, pre-treatment with polyaluminum chloride (PAC) at 50-150 mg/L may enhance performance. Jar testing with actual deinking process water is recommended.

FAQ

Q: How does nonionic PAM perform with different paper grades?
A: Our nonionic PAM works effectively across all recycled paper grades including newsprint, tissue, packaging board, and printing/writing paper deinking processes.

Q: Can this product handle shock loads of ink concentration?
A: Yes, the wide effective pH range (3-11) and ionic-strength independence of nonionic PAM provide robust performance even during process fluctuations and shock loading events.

Q: What is the expected water quality after DAF treatment?
A: Typical results: TSS reduced to below 50 mg/L, turbidity below 30 NTU, and ink particle removal above 95%. Results depend on influent characteristics and system optimization.

Q: Is on-site technical support available for paper mills?
A: Yes, our application specialists can visit your facility for DAF system evaluation, chemical program optimization, and operator training. Free samples available for laboratory and on-site trials.
