9. Professional FAQ (Polyacrylamide Expert FAQ)
1. What is the optimal grade of polyacrylamide for sludge dewatering?
For activated sludge, anionic polyacrylamide (molecular weight ≥15 million, 20–30% charge) is preferred, maximizing water removal and recovery efficiency. For oily sludge, cationic grades excel.
2. How does dry polyacrylamide compare with emulsion types?
Dry powder offers the highest activity (≥99%) and longer shelf life, ideal for global shipping/storage. However, it requires precision in dissolution and dosing. Emulsion is quicker to disperse/run but higher in cost and less storage-stable.
3. What are the critical inspection standards for polyacrylamide?
Respected standards include ISO 9001 for QMS, ANSI/NSF 60 for water safety, FDA 21 CFR 175.105 for food contact, and detailed GPC molecular distribution analysis. Viscosity and residual monomer are must-check indices.
4. Can OEM polyacrylamide formulas be customized?
Absolutely. Parameters like particle size, ionicity, viscosity, color, and branding are regularly customized based on project scenarios and regional standards (e.g., GB/T 17514, EN 1407).
5. What’s the best practice for polyacrylamide storage?
Keep dry powders in cool (<30°C), sealed packaging, away from sunlight and humidity. Avoid prolonged contact with oxidizers. Emulsions need mild agitation and must remain above freezing. Always refer to MSDS for site-specific advice.
6. Which test methods are used for polyacrylamide performance evaluation?
Key methods: Jar test (flocculation), Brookfield/Ubbelohde viscosity, Zeta potential, GPC (MW), and infrared spectrum (FTIR). Turbidity and sludge volume index (SVI) confirm real-world performance.
7. Is polyacrylamide environmentally safe?
Properly polymerized commercial polyacrylamide (residual monomer <0.05%) is non-toxic, non-carcinogenic, and fully compliant with global water safety guidelines; it's widely used in potable water production per NSF and FDA standards.
