Decolorizing Agent (Decolorant)
Basic Information
Name: Decolorizing Agent (Decolorant)
Other names: Decolorant; color removal agent
Product type: Composite decolorant for wastewater treatment (composite product, no molecular formula / CAS)
Composition: Dicyandiamide-formaldehyde condensate (DCD), quaternary ammonium polymers, and aluminum / iron salts
2.Physical and Chemical Properties
- Appearance: Colorless to light-yellow transparent liquid; white to light-yellow powder (solid grades)
- Solubility: Miscible with water
- Stability: Stable; store sealed, in a cool and dry place
3.Main Functions and Applications (What are its uses?)
- Wastewater decolorization (core application): Used for the decolorization of colored wastewater from printing & dyeing, papermaking, chemical and dye industries; through charge neutralization and adsorption-bridging, it rapidly flocculates and removes color-causing substances.
- Application industries: Printing & dyeing, papermaking, dyes, leather, food processing and chemical wastewater.
- Mechanism: Flocculation decolorization (organic polymeric decolorants) and adsorption decolorization (activated carbon / resin).
- Advantages: High color-removal efficiency (≥ 95%), low dosage, fast settling, low sludge volume and easy operation.
4.A Benchmark-Level Industrial Masterpiece - A Meticulously Crafted "Color Removal" Additive!
Color removal efficiency ≥ 95% with low dosage.
Suitable for printing & dyeing, papermaking and chemical wastewater. Fast settling and low sludge volume.
"What you see is what you get" - every lot ships with a complete certificate of analysis.
