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.

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 especially effective for disperse dye wastewater, where decolorization performance is particularly prominent.
Q What decolorization rate and COD removal can be expected?
The product achieves a decolorization rate of ≥95% for refractory pigments and a COD removal rate of ≥40%. Large flocs form within 3 minutes after dosing, enabling fast sedimentation and efficient separation of contaminants.
Q What pH range is the decoloring agent suitable for?
The product maintains stable effectiveness across a broad pH range of 3–11, with optimal performance at pH 6–9. This makes it compatible with more than 90% of industrial wastewater treatment scenarios without the need for significant pH adjustment.
Q Is the product suitable for high-salinity or high-temperature wastewater?
Yes. The decoloring agent is resistant to high salt concentrations (salinity ≤5%) and high temperatures, showing no performance degradation below 60°C. This makes it well-suited for challenging industrial effluent conditions such as those found in textile dyeing and chemical manufacturing.
Q What industries can benefit from using this water decoloring agent?
The product is applicable across a wide range of industries, including textile dyeing and printing, dye manufacturing, papermaking (black liquor treatment), electroplating (chromium/copper-containing wastewater), chemical industry (phenol/aniline-containing wastewater), pigment preparation, and ink production.
Q How is the product packaged and how should it be stored?
The liquid-type decoloring agent is available in 200L plastic drums and 1000L IBC totes for bulk applications. It should be stored in a cool, well-ventilated area away from direct sunlight to maintain product stability and effectiveness over time.
