BWD-01 Liquid Pre-Treatment Decolorizer Coagulation Aid Advanced Color Removal Polymer Water Decoloring Agent For Reactive Dyes Acid Dyes Organic Pigments
BWD-01 Liquid Pre-Treatment Decolorizer Coagulation Aid Advanced Color Removal Polymer Water Decoloring Agent
High Efficiency Pretreatment Decolorizer for Industrial Wastewater Color Removal COD Reduction and Coagulation Enhancement
Product Overview
BWD-01 Liquid Pre-Treatment Decolorizer is a high efficiency advanced color removal polymer specially developed for industrial wastewater pretreatment color removal COD reduction and coagulation aid applications.
The product is widely used in textile dyeing wastewater paper mill wastewater pigment wastewater printing ink wastewater landfill leachate and chemical wastewater treatment systems.
Industrial wastewater often contains stable soluble dyes organic color compounds colloidal particles and suspended solids that are difficult to remove through conventional coagulation alone.
In many wastewater treatment plants this results in dark effluent unstable sedimentation and excessive sludge generation.
BWD-01 Water Decoloring Agent is designed as a primary pretreatment solution that rapidly destabilizes color substances and improves coagulation performance before secondary treatment processes.
Why Pretreatment Is Important for Industrial Wastewater
Common Problems in High Color Wastewater
Industrial wastewater from textile dyeing printing paper production and chemical manufacturing often contains:
- Reactive dyes
- Acid dyes
- Organic pigments
- Fine colloidal particles
- Suspended solids
- High COD contaminants
Without effective pretreatment downstream treatment systems may experience:
- Poor color removal
- High biological treatment load
- Slow sedimentation
- Increased chemical consumption
- Excess sludge generation
- Unstable discharge quality
Pretreatment decolorization is therefore important for improving the efficiency of the entire wastewater treatment process.
Solution for Industrial Wastewater Pretreatment
Advanced Color Removal Polymer and Coagulation Aid
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 compounds and improve coagulation efficiency.
Treatment Performance
- Color removal efficiency 50 percent to 99 percent
- COD reduction efficiency 50 percent to 80 percent
- Faster flocculation and settling
- Lower sludge generation
Compared with traditional inorganic coagulants BWD-01 provides better pretreatment performance and improved clarification stability.
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 to 8.0

How It Works
Working Principle of Advanced Color Removal Polymer
After dilution BWD-01 is dosed directly into wastewater.
The cationic polymer rapidly adsorbs negatively charged dye molecules and colloidal particles helping form large and dense flocs.
The flocs are then separated through sedimentation or dissolved air flotation systems.
For wastewater with high COD or difficult color removal requirements PAC and PAM are usually combined to improve treatment performance.
