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 (3)
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.

Application Area
1. Wastewater Treatment in the Dye Industry:

Primarily addressing the decolorization needs of colored wastewater from dye production enterprises, it can be adapted to various types of dye wastewater, including reactive dyes, acid dyes, disperse dyes, etc.; especially in the treatment of disperse dye wastewater, its decolorization performance is more prominent.

2. Textile Dyeing and Related Industrial Wastewater:

Suitable for purifying mixed wastewater generated during textile dyeing and processing, and can also be extended to industrial wastewater treatment scenarios in areas such as pigment preparation, ink production, and the paper industry.

3. Auxiliary Treatment of High-Suspended Solids Wastewater:

For wastewater systems with relatively high suspended solids content, this product can achieve significant sedimentation through flocculation, thereby assisting in reducing the content of solid impurities in the wastewater.

Frequently Asked Questions
Q What types of dyes can the water decoloring agent effectively treat?
The water decoloring agent is effective against a broad 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 achieves a decolorization rate of ≥95% for most refractory pigments.
Q What is the recommended pH range for using this decoloring agent?
The product maintains stable effectiveness across a pH range of 3–11, with the optimal performance achieved at pH 6–9. This wide adaptability makes it suitable for the vast majority of industrial wastewater treatment scenarios.
Q How quickly does the water decoloring agent work after dosing?
After dosing, large flocs typically begin to form within 3 minutes, and the settling speed is fast. This rapid action minimizes treatment time and improves overall wastewater processing efficiency.
Q Is the decoloring agent suitable for high-salinity or high-temperature wastewater?
Yes. The product is resistant to high-salinity conditions (salinity ≤5%) and performs without degradation at temperatures up to 60°C, making it well-suited for challenging industrial wastewater environments such as those in the printing, dyeing, and chemical industries.
Q What packaging options are available, and how should the product be stored?
The product is available in 200L plastic drums and 1000L IBC totes. It should be stored in a cool, well-ventilated area away from direct sunlight to maintain product quality and performance over time.
Q Can this product be used for wastewater with high suspended solids content?
Yes. Through its flocculation mechanism, the decoloring agent can achieve significant sedimentation of suspended solids in addition to decolorization, making it effective as an auxiliary treatment agent for wastewater with high suspended solids content across industries such as papermaking, textiles, and chemical processing.
