DCA-58 Color Removal Agent For Denim Textile Dyeing Effluents Water Decoloring Agent
DCA-58 is a high-performance water decolorant with 50% solid content specifically formulated for wastewater color treatment applications in Bangladesh and international markets.
Chemical Type: Quaternary Ammonium Cationic Polymer
Form: Colorless to yellowish transparent liquid
Primary Functions: Color removal, COD reduction, and flocculation
- Excellent for removing dark blue/black dye from denim and knitwear processes.
- Speeds up flocculation and sedimentation in space-limited treatment plants.
- Helps exporters maintain compliance with global buyer requirements (H&M, Levi’s, etc.).
- Reduces dependency on high-dose inorganic coagulants.
- Enables reuse of treated water in non-critical processes.
- Bangladesh’s denim exports rely on heavy use of indigo dyes, causing dark effluents. Pressure from global buyers to comply with ZDHC.
- Removes 50-99% color and reduces COD by 50-80%
- Highly effective for Reactive, Acid, Disperse, and Direct dyes
- Fast reaction time, enhances floc formation and sedimentation
- Less sludge generation compared to traditional coagulants
- Compatible with PAC for improved performance and cost efficiency
- Safe, non-toxic, non-corrosive, fully water-soluble formulation
