Decolorant for Textile Wastewater

CAS: 55295-98-2

Dicyandiamide-formaldehyde polycondensate for reactive and direct dye removal from textile wastewater. High charge density for effective color neutralization.

decolorants

Ferrous Sulfate Decolorant

CAS: 7782-63-0

Low-cost iron-based decolorant for acid dye and direct dye wastewater. Combines coagulation with Fenton-like oxidative decolorization at acidic pH.

decolorants

High-Efficiency Decolorant (Quaternary Ammonium Type)

Quaternary ammonium polymer decolorant with dual charge neutralization and adsorption mechanism. Handles mixed dye wastewater including disperse and vat dyes.

decolorants

Hydrogen Peroxide 50% (Oxidative Decolorant)

CAS: 7722-84-1

Strong oxidant for color destruction in textile and paper wastewater. Used alone or with Fe²⁺ catalyst (Fenton reagent) for advanced oxidation of persistent dyes.

decolorants

PolyDADMAC for Wastewater Decolorization

CAS: 26062-79-3

High-charge-density PolyDADMAC (charge ≥1.5 meq/g, active content ≥40%) formulated for rapid decolorization of reactive dye, direct dye, and acid dye wastewater from textile, printing, and paper industries. Acts via charge neutralization and adsorption to destabilize negatively charged color bodies, achieving >95% color removal at low dosage.

decolorants

Sodium Hypochlorite 12% (Bleaching/Decolorant)

CAS: 7681-52-9

Liquid chlorine bleaching agent for oxidative decolorization and disinfection. Destroys color at low cost but requires dechlorination before discharge.
