High-Efficiency Polyacrylamide (PAM) Polymers for Industrial Wastewater Treatment

Issuing time:2020-07-06 10:35Author:LisaSource:WelldoneLink:http://www.welldonefloc.com

In an era of tightening environmental regulations and rising operational costs, industries worldwide are turning to advanced polyacrylamide (PAM) flocculants for cost-effective, high-performance wastewater treatment. Welldone Chemical Group’s specially formulated PAM polymers are engineered to address the toughest effluent challenges—from oil refineries to municipal sewage plants.

✔ How PAM works in wastewater treatment.   

✔ Key product types (Anionic, Cationic, Non-ionic) and their applications.   

✔ Real-world advantages over conventional solutions.

1. The Science Behind Polyacrylamide Flocculants

Polyacrylamide is a water-soluble polymer that acts as a ""molecular glue,"" binding suspended particles (colloids, oils, metals) into larger clumps (flocs) for easy removal.   

How It Works:

  • Charge Neutralization: Cationic PAM (+) attracts negatively charged particles (e.g., organic sludge).   

  • Bridging Mechanism: Long polymer chains ""bridge"" particles, forming dense flocs.   

  • Enhanced Settling: Flocs settle faster, reducing clarifier load and improving water clarity.   


""Our PAMs are optimized for rapid flocculation, cutting process time by 30–50% compared to generic polymers.""

2. Product Range & Applications

We offer **three primary PAM formulations**, each tailored to specific wastewater types:   

TypeBest For Example Applications
Anionic PAMMineral processing, sand washingMining effluent (Brazil, Chile)
Cationic PAMOrganic sludge, oil refineriesDubai oil refinery wastewater
Non-ionic PAMpH-sensitive effluents, textilesDye wastewater treatment (India)



Key Features:

  • High Molecular Weight: Up to 20 million g/mol for superior flocculation.   

  • Low Dosage Efficiency: 0.1–0.5 ppm achieves >90% turbidity reduction.   

  • Customizable: Adjustable charge density for specific effluent chemistries.

3. Competitive Advantages

A. Cost Savings

  • Reduces sludge volume by 60–80%, lowering disposal costs.   

  • 20% less polymer usage vs. standard PAMs (verified in Mexican municipal plants).   

B. Environmental Compliance

  • Helps clients meet EPA, EU, and GCC standards for heavy metals/BOD.   

  • Low residual acrylamide (<0.05%) for safe discharge.   

C. Ease of Use

  • Quick-dissolving granules for automated dosing systems.   

  • Stable performance** across pH 3–10 and high-salinity conditions.   


4. Case Study: Cationic PAM in UAE Oil & Gas

A UAE offshore oil platform reduced **oil-in-water content from 200 mg/L to <10 mg/L using our CPAM-80 series, saving $250,000/year in disposal fees.
