Performance Characteristics
Our Anionic PAM excels in flocculation efficiency, reducing turbidity and suspended solids by up to 95% in typical water treatment scenarios. Competitive benchmarking against leading manufacturers (e.g., SNF Floerger, BASF, Kemira) shows superior viscosity build-up and lower dosage needs (0.1-1 ppm vs. industry average 0.5-2 ppm), leading to cost savings of 15-20%.
- Flocculation Efficiency: Forms large, stable flocs for rapid sedimentation; effective in pH range 4-10.
- Shear Resistance: Maintains integrity under high shear, ideal for pumping and mixing.
- Temperature Stability: Functional from 0-80°C without degradation.
- Salt Tolerance: Performs well in brackish water (up to 5,000 ppm TDS).
- Environmental Impact: Biodegradable under aerobic conditions; low toxicity to aquatic life (LC50 >100 mg/L).
Application-specific benefits:
- Water Treatment: Enhances clarification in municipal and industrial wastewater, reducing sludge volume by 20-30%.
- Oil Recovery (EOR): Increases viscosity for better sweep efficiency, improving oil yield by 10-15%.
- Mining and Metallurgy: Aids in tailings management, minimizing water usage and environmental discharge.
- Paper Manufacturing: Improves retention and drainage, boosting production speed by 5-10%.
- Erosion Control: Binds soil particles on construction sites, reducing sediment runoff by 80-90%.
Quality Standard Compliance
- International Standards: ISO 9001 certified production; complies with ASTM D5979 for erosion control and AWWA B453 for water treatment.
- Regulatory Approvals: REACH registered (EU); NSF/ANSI 60 certified for potable water; FDA-compliant for indirect food contact.
- Regional Adaptations: Meets EU RoHS, China GB/T 31246, and US EPA guidelines for polyacrylamide use in environmental applications.
- Certifications Available: COA, MSDS, and third-party test reports upon request.
Packaging, Storage, and Handling
- Συσκευασία: 25 kg multi-layer paper bags with PE inner liner; 750-1000 kg big bags for bulk shipments. Custom packaging for international export (e.g., palletized, shrink-wrapped).
- Storage: Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Shelf life: 24 months under recommended conditions.
- Handling Precautions: Use PPE (gloves, goggles, dust mask) to avoid inhalation or skin contact. Slippery when wet—clean spills immediately with absorbent material. Not classified as hazardous under UN GHS, but refer to SDS for full details.
Safety and Environmental Information
- Toxicity: Non-toxic (oral LD50 >5,000 mg/kg); low bioaccumulation potential.
- Πρώτες βοήθειες: Skin/eye contact—rinse with water; inhalation—move to fresh air; ingestion—seek medical advice.
- Environmental Considerations: Biodegradable; avoid direct release into water bodies. Supports sustainable practices by reducing chemical usage in treatment processes.
- Import Regulations: HTS Code 3906.90; compliant with international trade requirements including IMDG for sea transport.
