Product Description

Core Features

• Multi-mechanism synergy: Integrating adsorption bridging, flocculation (cationic polymer bridging), and oxidation (trace oxidant decomposing pigments) into one, it achieves a decolorization rate of ≥95% (COD removal rate ≥40%) for refractory pigments such as reactive dyes (e.g., reactive red, reactive blue), direct dyes (e.g., direct yellow, direct black), and sulfur dyes.

Frequently Asked Questions

QWhat types of dyes can the water decoloring agent effectively treat?
The water decoloring agent is effective against a wide range of refractory dyes, including reactive dyes (e.g., reactive red, reactive blue), direct dyes (e.g., direct yellow, direct black), sulfur dyes, acid dyes, and disperse dyes. It is especially prominent in treating disperse dye wastewater.
QWhat decolorization and COD removal rates can be achieved?
The product achieves a decolorization rate of ≥95% and a COD removal rate of ≥40% for refractory pigments under recommended dosing conditions, making it highly effective for industrial wastewater treatment.
QWhat is the recommended pH range for using this decoloring agent?
The product maintains stable effectiveness across a broad pH range of 3–11, with the optimal performance achieved between pH 6–9. This makes it suitable for the vast majority of industrial wastewater scenarios without requiring significant pH adjustment.
QHow quickly does the decoloring agent work after dosing?
The product delivers rapid results — large flocs begin to form within just 3 minutes after dosing, with a fast settling speed that enables efficient separation and clarification of treated wastewater.
QIs this product suitable for high-salinity or high-temperature wastewater?
Yes. The decoloring agent is resistant to high salt concentrations (salinity ≤5%) and high temperatures (no performance degradation below 60°C), making it reliable for challenging industrial wastewater conditions including printing, dyeing, and chemical processing effluents.
QWhat packaging options are available and how should the product be stored?
The water decoloring agent is available in 200L plastic drums and 1000L IBC totes for flexible logistics. It should be stored in a cool, well-ventilated area away from direct sunlight to maintain product stability and shelf life.
