Cationic Flocculant for Color Removal Organic Cationic Coagulant Polymeric Color Removal Agent
Cationic Flocculant for Color Removal Organic Cationic Coagulant Polymeric Color Removal Agent
Product Overview
Bluwat BWD-01 Cationic Flocculant for Color Removal is a high-efficiency organic cationic coagulant specially developed for industrial wastewater decolorization, flocculation, and COD reduction applications. The product is based on quaternary ammonium polymer technology and is widely used in textile dyeing, pigment, printing ink, paper mill, and chemical wastewater treatment systems.
Industrial wastewater containing dyes, pigments, and organic color substances is often difficult to treat using traditional inorganic coagulants alone. Residual color, unstable settling, and excessive sludge generation are common operational problems.
BWD-01 Polymeric Color Removal Agent is designed to solve these challenges by rapidly destabilizing color molecules and forming dense flocs for faster separation and clearer treated water.
Why Industrial Wastewater Color Is Difficult to Remove
Common Problems in Color Wastewater Treatment
High-color wastewater usually contains:
- Reactive dyes
- Acid dyes
- Direct dyes
- Disperse dyes
- Organic pigments
- Soluble color molecules
- Fine suspended solids
Many conventional coagulants cannot effectively remove dissolved dye molecules, especially in textile and pigment wastewater treatment systems.
As a result, wastewater treatment plants may experience:
- Poor final effluent color
- High chemical consumption
- Excess sludge production
- Slow settling speed
- Unstable treatment performance
Solution for Wastewater Decolorization
High-Efficiency Organic Cationic Coagulant
BWD-01 works through strong cationic charge neutralization and polymer flocculation mechanisms.
The product rapidly reacts with negatively charged dye molecules and colloidal particles in wastewater, helping destabilize color substances and improve sedimentation efficiency.
Treatment performance:
- Color removal efficiency: 50%–99%
- COD reduction efficiency: 50%–80%
- Faster flocculation and settling
- Lower sludge generation
Compared with traditional inorganic coagulants, the product offers better treatment stability and lower overall operating cost in many industrial applications.

How It Works
Working Principle of Polymeric Color Removal Agent
The treatment process mainly includes:
- Charge neutralization
- Color destabilization
- Polymer bridging
- Flocculation and sedimentation
After dilution, the product is dosed directly into wastewater. The cationic polymer rapidly adsorbs and neutralizes negatively charged dye particles.
Large and dense flocs are formed, allowing rapid separation through sedimentation or dissolved air flotation systems.
For high-COD wastewater, the product is often used together with PAC and PAM to improve treatment efficiency.
Recommended dosing sequence:
BWD-01 → PAC → PAM
Recommended pH range:
7.5–8.0
How To Choose the Right Cationic Flocculant
Choose Based on Wastewater Type
Different industries generate different wastewater characteristics:
- Textile wastewater contains high soluble dye concentration
- Ink wastewater often contains fine colloidal particles
- Leachate wastewater usually contains high COD and dark color
Jar testing is recommended to optimize dosage and treatment performance.
Evaluate Sludge Generation
Traditional inorganic coagulants often produce excessive sludge volume.
Organic cationic polymeric coagulants like BWD-01 help reduce sludge production and lower sludge disposal cost.
Consider Treatment Stability
For continuous industrial wastewater systems, stable treatment performance is important.
BWD-01 provides:
- Faster settling
- Stable clarification
- Lower dosage fluctuation
- Better color removal consistency
