PolyDADMAC for Wastewater Decolorization
CAS Number: 26062-79-3
High-charge-density PolyDADMAC (charge ≥1.5 meq/g, active content ≥40%) formulated for rapid decolorization of reactive dye, direct dye, and acid dye wastewater from textile, printing, and paper industries. Acts via charge neutralization and adsorption to destabilize negatively charged color bodies, achieving >95% color removal at low dosage.

Applications
- Textile dyeing and printing wastewater decolorization
- Reactive dye and direct dye color removal
- Paper mill effluent color reduction
- Ink manufacturing wastewater treatment
- Leather tannery effluent color control
- Municipal wastewater receiving high-color industrial discharge
Key Features
- High charge density (≥1.5 meq/g) neutralizes anionic dye molecules at low dosage (20–100 mg/L)
- Effective against reactive, direct, and acid dyes — broad dye class coverage
- Produces compact, easy-to-dewater floc when used with PAC or coagulant aid
- Free of heavy metals and compliant with textile effluent discharge standards
- Liquid form — easy dosing with metering pump, no preparation required
