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 this water decoloring agent treat?
This 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 is especially prominent in treating disperse dye wastewater, achieving a decolorization rate of ≥95%.
Q What is the effective pH range for this decoloring agent?
The product maintains stable effectiveness across a wide pH range of 3–11, with the optimal performance achieved at pH 6–9. This makes it suitable for the vast majority of industrial wastewater treatment scenarios without requiring strict pH pre-adjustment.
Q How quickly does the decoloring agent work after dosing?
The product acts rapidly — large flocs begin to form within just 3 minutes after dosing, with a fast settling speed. This significantly reduces treatment cycle time and improves overall wastewater processing efficiency.
Q Is this decoloring agent suitable for high-temperature or high-salinity wastewater?
Yes. The product is engineered to withstand high-salt environments (salinity ≤5%) and elevated temperatures (no performance degradation below 60°C), making it well-suited for challenging industrial wastewater conditions such as those found in textile dyeing and chemical manufacturing.
Q What industries can benefit from 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 What packaging options are available and how should the product be stored?
The liquid product is available in 200L plastic drums and 1000L IBC totes to accommodate different usage scales. For storage, keep the product in a cool, well-ventilated area away from direct sunlight to maintain its stability and effectiveness over time.
