PolyDADMAC for Textile Wastewater Treatment and Color Fixing

Bluwat Chemicals — polymer solutions for dyeing plants and ETPs

Overview

Bluwat Chemicals supplies PolyDADMAC grades tailored for textile manufacturing and effluent treatment. With high cationic charge density and flexible molecular weight options, PolyDADMAC enhances color fixing on fabrics and provides efficient decolorization and clarification for dye wastewater from cotton, polyester, and blended operations.

Color fixing Dye wastewater decolorization ETP clarification

Why PolyDADMAC in Textile Applications

  • Improves dye uptake and wash fastness when used as a color fixing agent.
  • Rapid charge neutralization forms compact flocs, cutting color and suspended solids in effluents.
  • Works alone or alongside polyaluminum coagulants to optimize jar tests and treatment cost.
  • Wide pH adaptability supports variable dye baths and ETP conditions.

Product Grades and Technical Data

Liquid Series (Blu DA)

Parameter Typical range Notes
Solid content ~20–50% Multiple grades for process flexibility
Brookfield viscosity (25°C) <200 to >15000 cps Low to very high molecular weight options
pH (as supplied) ~3.0–7.0 Stable liquid, easy handling
Operating pH window ~0.5–14 Supports diverse raw water and dye effluents
Appearance Colorless to light yellow liquid Consistent quality

Powder Series (Blu DA9001)

Parameter Typical value Notes
Solid content ≥90% Dry handling, economical transport
1% solution pH ~2.0–6.0 Prepare with compatible materials
Viscosity (10% solution) ~50 to >150 cps Low to high MW selection
Charge density ~2–3 meq/g Strong cationic performance
Specific gravity ~0.90–1.04 Bulk property reference
Operating pH window ~5–14 Process robustness
Appearance White to light yellow powder Uniform quality

Textile Use Cases

  • Color fixing agent: improves fastness, reduces back staining after dyeing.
  • Dye wastewater treatment: decolorization and turbidity reduction in ETP primary treatment.
  • Process water reuse: clarification of recirculation streams to save fresh water.
  • Sludge conditioning: supports thickening and dewatering for reduced disposal cost.

Dosage and Use

Liquid grade make-up
Dilute to 0.5–5% by solids before dosing into dye bath post-treatment or ETP coagulation step.
Powder grade make-up
Prepare 0.5–10% solution; allow full dissolution prior to dosing.
Optimization
Jar test with representative effluent; adjust dose, pH, and mixing to protect floc integrity.
Program pairing
Can be paired with polyaluminum coagulants for high-color or high-NOM scenarios.

Packaging and Storage
