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
What types of dyes can this water decoloring agent effectively treat?
This 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 achieves a decolorization rate of ≥95%, making it suitable for highly colored industrial wastewater from dye manufacturing, textile dyeing, and related industries.
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 the optimal performance observed at pH 6–9. This wide adaptability makes it suitable for over 90% of industrial wastewater treatment scenarios without requiring significant pH pre-adjustment in most cases.
How quickly does the decoloring agent work after dosing?
The decoloring agent acts rapidly. Large, visible flocs typically form within 3 minutes of dosing, and the flocs settle quickly, enabling efficient separation of contaminants from the treated water in a short processing time.
Is this product suitable for high-salinity or high-temperature wastewater?
Yes. The decoloring agent is formulated to resist high-salinity conditions (salinity ≤5%) and elevated temperatures (no performance degradation below 60°C). This makes it well-suited for demanding industrial environments such as textile dyeing, electroplating, and chemical processing facilities.
What packaging options are available, and how should the product be stored?
The product is available in liquid form, packaged in 200L plastic drums or 1000L IBC totes for bulk orders. It should be stored in a cool, well-ventilated area away from direct sunlight to maintain its quality and effectiveness over time.
Can this decoloring agent also help reduce COD and suspended solids in wastewater?
Yes. In addition to achieving a decolorization rate of ≥95%, the product achieves a COD removal rate of ≥40% through its integrated multi-mechanism action — combining adsorption bridging, cationic polymer flocculation, and trace oxidation. For wastewater with high suspended solids content, the flocculation mechanism also promotes significant sedimentation, effectively reducing solid impurity levels.
