Anionic Polyacrylamide CAS 9003-05-8

Polymer Anionic Polyacrylamide (PAM) CAS 9003-05-8 is a high–molecular-weight, water-soluble flocculant widely used in municipal and industrial wastewater treatment, mining, and oilfield projects. It provides fast settling, clear overflow water and low sludge volume, helping end users reduce operating costs and meet discharge standards.

Applications

1. Municipal & Industrial Wastewater Treatment
   • Coagulation and flocculation of suspended solids, colloids and organic matter
   • Clarification of effluent in municipal WWTPs, chemical plants, steel mills, electroplating, textile dyeing, food processing, etc.
   • Used together with PAC, alum or ferric salts to improve settling speed and reduce polymer dosage
2. Sludge Thickening & Dewatering
   • Conditioning of primary, secondary and mixed sludge
   • Suitable for belt filter presses, centrifuges and chamber filter presses
   • Enhances cake dryness, reduces polymer consumption per ton DS, and lowers disposal cost
3. Mining, Mineral Processing & Coal Washing
   • Thickening and clarification of tailings slurry
   • Flocculation in coal preparation plants, iron ore, non-ferrous metal and gold mines
   • Improves overflow water clarity and reduces loss of fine solids
4. Oil & Gas Field Chemicals
   • Additive in drilling fluids as a viscosifier and filtration loss reducer
   • Friction reducer in fracturing and pipeline transportation
   • Polymer flooding agent for EOR in suitable reservoirs
5. Paper & Pulp Industry
   • Retention and drainage aid for fine fibers and fillers
   • Improves paper sheet formation and machine runnability
6. Other Uses
   • Clarification of sugar juice, juice and beverage processing
   • Clarification of wastewater in metallurgy, electronics and other industrial sectors

Storage Conditions

• Store in cool, dry, well-ventilated warehouses, away from direct sunlight and moisture.
• Keep bags tightly sealed after each use to prevent caking and loss of performance.
• Avoid contact with strong oxidizing agents and strong acids/alkalis.
• Recommended storage temperature: below 30 °C; avoid long-term exposure to high humidity.
• Under proper storage conditions, typical shelf life is 24 months from production date.

Safety Precautions

Polyacrylamide itself is generally regarded as having low acute toxicity and many grades are not classified as hazardous substances under common chemical regulations.
However, trace residual acrylamide monomer and polymer dust require careful handling:

• Avoid inhalation of dust and contact with eyes or skin; wear dust masks / respirators, protective gloves and safety goggles during handling or bag opening.
• In case of eye contact, rinse immediately with plenty of water; if irritation persists, seek medical advice.
• Spilled dry product and prepared solution can make floors extremely slippery; clean up spills promptly with dry absorbent and plenty of water.
• Do not discharge concentrated solutions directly into the environment; follow local regulations for wastewater and sludge disposal.
• Keep away from food, feed and drinking water. Workers should wash hands thoroughly after handling.
