The printing and dyeing industry is a significant contributor to industrial wastewater, often characterized by high color intensity and recalcitrant organic pollutants. Treating this type of effluent effectively is a critical challenge. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing advanced chemical solutions, and our iron-carbon micro-electrolysis fillers have proven to be exceptionally effective in tackling printing and dyeing wastewater.

Wastewater from printing and dyeing processes typically contains a complex mixture of dyes, pigments, auxiliary chemicals, and organic compounds. The vibrant colors of these dyes are often caused by chromophoric organic groups within their molecular structure. Conventional treatments can struggle to break down these stable structures, leading to persistent color and high COD levels in the discharged water. This is where the unique properties of iron-carbon micro-electrolysis fillers come into play.

The core mechanism of the filler involves electrochemical reactions that generate powerful oxidizing agents, such as hydroxyl radicals. These radicals are highly effective at attacking and breaking down the complex organic molecules responsible for dye color. By cleaving these chromophoric groups, the filler facilitates significant decolorization of the wastewater. This is a crucial step in making the water compliant with environmental discharge standards and is a key benefit for companies looking to purchase effective treatment materials.

In addition to decolorization, the fillers are instrumental in reducing the Chemical Oxygen Demand (COD) of the wastewater. The oxidizing power of the generated radicals breaks down a broad spectrum of organic pollutants, converting them into simpler compounds like carbon dioxide and water. This leads to a substantial reduction in COD, which is a critical parameter indicating the overall organic load of the wastewater. The effectiveness of our fillers in achieving higher COD removal rates makes them an indispensable part of advanced wastewater treatment solutions for this sector.

Furthermore, the adsorption and flocculation properties of the generated iron hydroxides play a supplementary role. These precipitates can capture remaining suspended color particles and other contaminants, aiding in their removal from the water. For the printing and dyeing industry, implementing these fillers offers a dual benefit: achieving visible decolorization and significantly lowering the overall organic burden. NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer these advanced catalysts that help make challenging wastewater treatment processes more efficient and environmentally sound.
