Dicyandiamide Resin Decolorizing Agent Decolourant Water Purification Chemicals for Water Treatment
Organic Polymer Decolorizing Chemical for Pigment Reactive Ink Dye Wastewater Treatment
Product Overview
BWD-01 Organic Polymer Decolorizing Chemical is a high-efficiency cationic polymer specially developed for pigment wastewater, reactive dye wastewater, printing ink wastewater, and industrial color removal treatment applications. The product is widely used in textile dyeing plants, pigment manufacturing factories, printing ink production, paper mills, and chemical wastewater treatment systems.
Industrial wastewater containing pigments, reactive dyes, inks, and organic color compounds is often difficult to treat using traditional inorganic coagulants alone. Residual color, unstable clarification, and excessive sludge generation are common operational problems in wastewater treatment plants.
BWD-01 Water Decoloring Agent is designed to rapidly destabilize color substances and improve flocculation performance, helping achieve clearer treated water and more stable wastewater treatment efficiency.

Why Pigment and Dye Wastewater Are Difficult to Treat
Common Problems in Color Wastewater Treatment
Pigment and dye wastewater usually contains:
- Reactive dyes
- Acid dyes
- Organic pigments
- Printing inks
- Fine colloidal particles
- Suspended solids
- High COD organic contaminants
Many dissolved dye molecules and pigment particles are stable in wastewater and difficult to remove through conventional coagulation processes.
As a result, treatment systems may experience:
- Dark final effluent
- Poor discharge quality
- Slow sedimentation
- Excess sludge generation
- High chemical consumption
- Unstable treatment performance
Solution for Pigment and Reactive Dye Wastewater
High-Efficiency Organic Polymer Decolorizing Chemical
BWD-01 works through strong cationic charge neutralization and polymer flocculation mechanisms.
The product rapidly reacts with negatively charged dye molecules, pigment particles, and colloids in wastewater, helping destabilize color compounds and form dense flocs for easier separation.
Treatment performance:
- Color removal efficiency: 50%–99%
- COD reduction efficiency: 50%–80%
- Faster flocculation and settling
- Lower sludge generation
Compared with conventional inorganic coagulants, BWD-01 provides stronger decolorization capability and more stable clarification performance.
For difficult wastewater systems, the product is commonly used together with PAC and PAM.
Recommended treatment sequence:
BWD-01 → PAC → PAM
Recommended operating pH:
7.5–8.0

How It Works
Working Principle of Organic Polymer Decolorizer
The treatment process mainly includes:
- Charge neutralization
- Dye and pigment destabilization
- Polymer bridging
- Flocculation and sedimentation
After dilution, BWD-01 is dosed directly into wastewater.
The cationic polymer rapidly adsorbs negatively charged dye molecules and pigment particles, helping form large and dense flocs.
These flocs are then separated through sedimentation or dissolved air flotation systems.
For wastewater with high COD or strong residual color, PAC and PAM are commonly combined to improve treatment efficiency and settling performance.
How To Choose the Right Decolorizing Chemical
Choose According to Wastewater Type
Different wastewater systems contain different contaminants:
- Reactive dye wastewater contains soluble dye molecules
- Pigment wastewater contains fine suspended solids
- Ink wastewater contains emulsified particles and resins
Jar testing is strongly recommended before full-scale dosing.
Evaluate Treatment Performance
