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.

Water decoloring agent (2)

• Broad pH Adaptability: Stable effectiveness at pH 3–11 (optimal pH 6–9), resistant to high salt (salinity ≤5%), and high temperature (no performance degradation below 60°C), suitable for over 90% of industrial wastewater scenarios such as printing and dyeing (high chroma), papermaking (black liquor), electroplating (chromium/copper-containing wastewater), chemical industry (phenol/aniline-containing wastewater), etc.

• Quick Results: Large flocs form within 3 minutes after dosing, with a fast settling speed.

Frequently Asked Questions
Q What types of dyes can the water decoloring agent effectively treat?
The water decoloring agent is effective against a wide range of dye types, 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 particularly effective in treating disperse dye wastewater, achieving a decolorization rate of ≥95%.
Q What is the recommended pH range for using this decoloring agent?
The product maintains stable effectiveness across a broad pH range of 3–11, with an optimal performance window of pH 6–9. This wide adaptability makes it suitable for over 90% of industrial wastewater treatment scenarios without requiring significant pH pre-adjustment.
Q How quickly does the water decoloring agent work after dosing?
The decoloring agent acts rapidly. Large flocs typically form within 3 minutes after dosing, and the settling speed is fast. This quick reaction time makes it highly practical for continuous industrial wastewater treatment processes.
Q Is this product suitable for high-salinity or high-temperature wastewater?
Yes. The water decoloring agent is formulated to be resistant to high-salt environments (salinity ≤5%) and high temperatures (no performance degradation below 60°C). This makes it highly versatile for demanding industrial conditions such as printing and dyeing, electroplating, and chemical processing wastewater.
Q What packaging options are available and how should the product be stored?
The liquid-type decoloring agent is available in 200L plastic drums and 1000L IBC totes for bulk usage. It should be stored in a cool, well-ventilated area away from direct sunlight to maintain its performance and shelf life.
Q Can this decoloring agent also reduce COD levels in wastewater?
Yes. In addition to achieving a decolorization rate of ≥95%, the product also delivers a COD removal rate of ≥40%. Its multi-mechanism approach — combining adsorption bridging, cationic polymer flocculation, and trace oxidant decomposition — contributes to overall improvement in wastewater quality beyond just color removal.
