Introduction
Bluwat Chemicals provides NSF-certified Polydadmac for potable
water purification and safe drinking water clarification. With
strong charge density and versatile molecular weight options, our
polymer enhances municipal water treatment by reducing turbidity,
suspended solids, and natural organic matter.
Why Choose NSF-Certified Polydadmac
- Certified under NSF standards for drinking water treatment.
- Effective charge neutralization and rapid floc formation.
- Can replace or reduce alum and ferric salts as primary coagulants.
- Broad pH adaptability: liquid ~0.5–14, powder ~5–14.
- Improved sludge dewatering and lower residuals.
Product Forms
Liquid Grades (Blu DA Series)
- Solids: ~20–50%
- Viscosity at 25°C: <200 cps up to >15000 cps
- pH (as supplied): ~3.0–7.0
- Appearance: colorless to light yellow liquid
Powder Grades (Blu DA9001 Series)
- Solids: ≥90%
- 1% solution pH: ~2.0–6.0
- Viscosity (10% solution): 50 cps to >150 cps
- Charge density: ~2–3 meq/g
- Appearance: white to light yellow powder
Typical Applications
- Raw water clarification from rivers, lakes, and reservoirs.
- Reduction of turbidity and suspended solids for safe drinking
water.
- Natural organic matter removal for disinfection byproduct control.
- Used alone or with polyaluminum chloride for enhanced coagulation.
- Stabilizes filter performance and lowers sludge production.
Dosage and Use
Liquid grades should be diluted to 0.5–5% solids; powder grades to
0.5–10%. Optimum dosage depends on raw water conditions and should
be determined by jar testing. Proper mixing ensures uniform
dispersion and protects floc integrity.
