BWD-01 Water Decolorant in Printing Water Treatment Chemicals Cationic Polymer Type 50% Solid Content
- DCA-58 Water Decolorant is a high-efficiency chemical agent specially developed for removing color from printing and dyeing wastewater. It effectively eliminates soluble dyes, pigments, and organic color substances through charge neutralization and strong adsorption.
- It is widely used in printing factories, textile dyeing plants, and ink production wastewater treatment systems.
- Water Decolorant is a cationic polymer compound. It neutralizes negatively charged dye molecules in wastewater and forms large flocs that can be easily removed by sedimentation or filtration
- Typical dosage: 50–300 ppm
Product Features
✔ Excellent color removal efficiency (90–99%)
✔ Effective for reactive, acid, disperse, and direct dyes
✔ Fast floc formation and sedimentation
✔ Low sludge volume
✔ Easy to operate
✔ Works well with PAC and PAM
