Key Features

Narrow Molecular Weight Distribution:

Controlled chain growth polymerization minimizes low-molecular-weight fractions, preventing residual polymer carryover in the supernatant.

Rapid Hydration Kinetics:

Surface-treated granule morphology prevents agglomeration ("fish-eyes") during automatic makeup, ensuring complete dissolution within standard aging tanks.

High Charge Consistency:

Precision dosing of ionic comonomers maintains charge density within +/- 2% across production batches, stabilizing flocculation performance in variable influent conditions.

Low Residual Acrylamide:

Monomer conversion rates exceeding 99.95% comply with strict environmental regulations for municipal discharge and paper contact applications.

Applications

Municipal Sludge Dewatering: Applied in belt filter presses, centrifuges, and screw press dehydrators to flocculate digested and extended aeration sludges, reducing cake moisture to target disposal levels.

Industrial Wastewater Treatment: Used in the coagulation-flocculation of high-turbidity effluent from textile dyeing, paper mills, steel mill rolling wastewater, and chemical processing plants.

Mineral Processing & Tailings: Accelerates sedimentation rates of mineral slurries in copper, gold, iron ore, and coal washing circuits, improving water recycle efficiency in thickeners.

Papermaking Retention & Drainage: Functions as a wet-end additive to retain fillers and fine fibers, enhancing paper sheet formation and increasing drainage speeds on the wire.

Product Selection Guide

Selecting the correct Polyacrylamide grade requires matching polymer charge and molecular weight to your specific suspension chemistry. Follow this workflow:

Determine Effluent/Sludge Type:
Negatively charged suspended solids (e.g., metallic hydroxides, biological sludge, silica) typically require Cationic PAM (CPAM).
Positively charged or neutral solids (e.g., iron/steel plant effluent, coal washing) typically require Anionic PAM (APAM).
Acidic or high-electrolyte systems often require Non-Ionic PAM (NPAM).

Conduct Jar Tests:
Prepare a 0.1% stock solution of candidate PAM grades.
Test dosages ranging from 1 ppm to 10 ppm (or kg/dry ton for sludge).
Evaluate parameters: Flake size, settling velocity, supernatant clarity, and shear resistance of the floc.

Send your water chemistry report (pH, TDS, turbidity, temperature) to our technical team for a formulation recommendation.

Manufacturing & Quality Control

Polymerization Process:

Aqueous solution polymerization is conducted in temperature-controlled reactors under an inert nitrogen blanket to ensure uniform polymer chain extension.

Granulation & Milling:

Gels are extruded, dried using multi-stage fluidized bed dryers, and milled to a uniform particle size distribution (20 - 60 mesh), minimizing dust generation during handling.

Batch Testing Protocol:

Every production lot undergoes rigorous inspection before packaging. Viscosity, molecular weight, solid content, and residual monomer are verified using Ubbelohde viscometers and High-Performance Liquid Chromatography (HPLC).

Traceability:

Each bag is labeled with a unique batch number mapped directly to production logs, raw material supplier certificates, and retention samples kept for 12 months.

Frequently Asked Questions

Q: How do I prevent "fish-eyes" (undissolved gel lumps) when preparing the PAM stock solution?

A: Ensure your dissolution system utilizes a mechanical agitator running at 400 - 800 RPM to create a strong vortex. Slowly sift the dry powder into the side of the vortex—never dump powder directly into still water or add it too quickly. Maintain water temperature between 10 deg C and 30 deg C and allow 45 - 60 minutes for complete hydration before dosing.

Q: What is the shelf life of solid Polyacrylamide powder, and how should it be stored?

A: Unopened solid PAM has a shelf life of 24 months when stored in dry conditions between 5 deg C and 30 deg C. Once opened, the bag should be tightly sealed immediately after use, as the product is hygroscopic and will absorb moisture from the air, leading to caking.

Q: Can I switch between different ionic types of PAM without flushing my dosing system?

A: No. Mixing residual anionic and cationic polymers directly in transfer lines or pumps can cause cross-reaction, resulting in insoluble gel precipitation that severely clogs pipelines and injection quills. Flush lines thoroughly with clean water when changing polymer types.

Q: How does water temperature affect the dissolution and performance of Polyacrylamide?

A: Colder water (< 10 deg C) significantly increases solution viscosity and slows down the hydration rate, requiring longer mixing times. Conversely, water temperature above 40 deg C can cause polymer chain thermal degradation, reducing molecular weight and weakening flocculation efficiency.
