DCA 58 Printing Ink Waste Water Color Removal Polyelectrolyte Water Treatment 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
DCA Polymer —a dicyandiamide formaldehyde resin—binds finely dispersed pigments, stabilizers, and surfactants that resist conventional coagulation. It supports fast floc growth and better separation, reducing carryover to biological stages and improving final effluent clarity.
- Works effectively on effluents with heavy dye and organic loads.
- No heavy metals or toxic residues — safe for irrigation discharge.
- Simple dosing and fast action — ideal for low-tech systems.
- Significantly improves turbidity and odor profile.
- Helps industries comply with NESREA and state-level regulations.
- High pollution from dyeing and tanning industries in Tanzania and Nigeria.
- 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
