Ink Waste Water Color Removing Decoloring Agent Water Treatment Industrial
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-58 Water Decoloring Agent is a special product for de-coloring, flocculating, CODcr decreasing and other applications. It is used to remove color of waste water generated by textiles process houses and dyes industries and other fields, with strong decolorization (50%~99%) and removal of COD (50%~80%).
-
By providing a large number of cations, the negative charge is brought on dye molecules are neutralized instability, at the same time with DCA-58 by a large number of hydrolysis of flocs, so as to achieve the purpose of decolorization.
-
DCA-58 Water Decoloring Agent is specially working high performance with the dyeing wastewater containing the hydrophilic dyes, less dosage, fast speed, and also decrease the composition of COD.
-
Application: wastewater treatment in paint industry, industrial waste water treatment, flocculation water treatment, water clarifying agent, water purifying agents, decolouring agent, cationic polymers water treatment
TEST CONTENT
A. EFFLUENT CONTENT
This effluent sample are mostly from Ink waste water, dark blue, and PH value 2.0
B.Chemical usage
The water treatment chemicals used in the experiment were diluted to a corresponding
C.Test process
As per customers requirements, we test this effluent by 2methods.
Take 50ml effluent, adjust PH value to 7-9, and add 0.4ml DCA-58, mix and add 1ml PAC, and mix again. Keep PH about 7. And then add PAM solution. After these process,the effluent become light blue. Check as below pictures.

- Dilute DCA-58 with tap-water, to get 5% solution before use.
- Ajust the effluent sample pH to 7.5-8.0, then add 100-200ppm DCA-58 solution
- Mix for several minutes to form flocs, and check the dosing rate.
- Combine with PAC-300 if needed – do not pre-mix
- Dose PAM solution for quick settlling
- Allow settling or use flotation for separation
