Nonionic Polymer Flocculant for Acidic & High-Salinity Wastewater
Nonionic PAM | Special Conditions
High-performance Nonionic Polyacrylamide designed for stable flocculation and solid–liquid separation in acidic, alkaline, and high-salinity wastewater systems.
What Is Nonionic Polyacrylamide (NPAM)?
Nonionic Polyacrylamide (NPAM) is a water-soluble, high-molecular-weight polymer flocculant that contains no ionic functional groups along its molecular chain.
As a professional NPAM manufacturer and supplier, we provide nonionic polymer flocculants designed for wastewater systems where particle charge characteristics are unclear, unstable, or strongly affected by extreme pH or high salinity.
Unlike anionic or cationic polyacrylamide, NPAM relies on adsorption and polymer bridging rather than electrostatic attraction. Its neutral molecular structure ensures stable flocculation performance in acidic, alkaline, and high-electrolyte environments, making it an ideal solution for complex industrial wastewater and mineral-rich systems.

Main Applications of Nonionic Polyacrylamide
NPAM delivers stable flocculation performance in wastewater systems with extreme pH values or high dissolved salt content, where ionic PAM types may show reduced efficiency.
Used for mine water clarification, tailings settling, and slurry thickening in mineral-rich and mixed-charge wastewater.
Improves fine particle aggregation, sedimentation, and water recycling efficiency in sand washing and aggregate processing plants.
Applied in black liquor pretreatment, white water clarification, and wastewater treatment under strongly alkaline conditions.
Used as a sizing agent and slurry conditioner, improving yarn protection, viscosity stability, and wastewater clarification.
Effective for construction mud, shield tunneling slurry, and complex industrial suspensions requiring charge-independent flocculation.

Recommended Dosage & Usage of NPAM
NPAM must be fully pre-dissolved before dosing.
Recommended solution concentration: 0.1–0.3%
Typical dosage: 0.02–8 mg/L, depending on water quality
Add granules slowly into stirred water to prevent agglomeration
Dissolving time: 60–120 minutes, depending on temperature
Jar testing is strongly recommended to determine the optimal NPAM grade and dosage for each application.
