Product Introduction：

The decolorizing agent for tannery wastewater is a specialized chemical formulation designed to remove colorants from tannery effluent. It belongs to the category of flocculating decolorizing water treatment agents and is typically composed of compounded organic high-molecular-weight polymers. Tannery wastewater originates from various stages of leather production—including beamhouse operations, tanning, and dyeing—and contains high concentrations of proteins, fats, inorganic salts, suspended solids, sulfides, chromium, vegetable tannins, and other toxic and hazardous substances. This wastewater is characterized by large discharge volumes, high pH, intense coloration, a wide variety of pollutants, and complex composition. The decolorizing agent functions primarily through flocculation, causing colorants and certain pollutants in the tannery wastewater to coagulate and precipitate, thereby achieving effective decolorization and reduction of pollutant levels.

Product Advantages：

Multifunctional: Integrates decolorization, flocculation, COD reduction, BOD reduction, and other functions into a single agent. It not only effectively removes color from wastewater but also reduces the concentrations of COD, suspended solids (SS), ammonia nitrogen, total phosphorus, and other pollutants. This significantly alleviates the load on downstream treatment processes and enhances the efficiency of the biological treatment stage.

High adaptability: Offers broad-spectrum decolorization performance, does not interfere with the biological treatment system, and features a simple dosing process, making it well-suited to the complex and variable water quality characteristics of tannery wastewater.

Excellent decolorization performance: Specifically formulated to address the color issues in tannery wastewater, it achieves high decolorization efficiency with no secondary color reversion, ensuring that the treated effluent meets national discharge standards for color.

Low dosage and fast action: Requires only a small amount of addition, and achieves rapid decolorization, flocculation, and sedimentation, enabling quick solid-liquid separation and effectively resolving water pollution in a single treatment step.

Environmentally friendly and non-polluting: Non-toxic and residue-free, it generates minimal sludge during COD removal and does not cause secondary pollution.

Service Industries：

Primarily serves the leather industry, helping tanneries treat high-color wastewater generated during production to meet environmental discharge standards and reduce pollution of surrounding water bodies. Additionally, thanks to its excellent decolorization and contaminant-reduction capabilities, it is also suitable for treating industrial wastewater from sectors such as textile, dyeing, ink, rubber, and chemical manufacturing.
