Water Decoloring Agent Dicyandiamide Polymer Color Removal Chemical for Dye Wastewater
Product Overview
BWD-01 Water Decoloring Agent is a dicyandiamide-based cationic polymer, belonging to the class of quaternary ammonium polymers, specifically developed for high-efficiency dye wastewater treatment.
This advanced polymer structure enables strong interaction with negatively charged dye molecules and colloidal particles, making it highly effective in removing color and improving water clarity.
Compared to conventional coagulants, BWD-01 provides a more targeted and efficient approach for treating wastewater with complex dye compositions.
Technical Features
Dicyandiamide Polymer Structure
Provides strong adsorption and charge neutralization capability for dye molecules.
High Reactivity with Dye Compounds
