PolyDADMAC for Dye Wastewater Decolorization and Textile Effluent Treatment
Bluwat Chemicals — polymer solutions for fabric color fixing and ETP clarification
Overview
Bluwat Chemicals supplies PolyDADMAC grades tailored for the textile industry. With high cationic charge density and flexible molecular weight options, PolyDADMAC enhances fabric color fixing and enables efficient dye wastewater decolorization and clarification in textile effluent treatment plants.
Why Use PolyDADMAC in Textile Processes
- Improves dye uptake and wash fastness when used as a color fixing agent.
- Rapid charge neutralization forms compact flocs, reducing color and suspended solids in effluents.
- Compatible with polyaluminum coagulants to optimize cost and performance.
- Wide pH adaptability supports variable dye baths and ETP conditions.

Textile Use Cases
- Fabric color fixing: improves fastness and reduces back staining after dyeing.
- Dye wastewater decolorization: removes residual color from reactive, disperse, and direct dye effluents.
- ETP coagulation and clarification: cuts turbidity and supports filterability.
- Process water recycling: clarifies recirculation streams to save fresh water.
- Sludge conditioning: assists thickening and dewatering to lower disposal cost.
