"Micro-electrolysis wastewater treatment technology" is specifically designed for treating high-concentration organic wastewater that is toxic, highly colored, and difficult to biodegrade. This advanced method significantly reduces the color and COD (Chemical Oxygen Demand) of the wastewater while increasing the B/C ratio, thereby improving its biodegradability. It is widely applied in industries such as printing and dyeing, chemicals, electroplating, papermaking, pharmaceuticals, scouring, pesticides, and alcohol production, as well as in water reuse projects. Puyinworun Environmental Protection Co., Ltd. is a professional manufacturer and supplier of micro-electrolysis fillers, including iron-carbon materials. Our company has been specializing in the development and production of these fillers since 2013, offering unique advantages such as no consolidation, low loss, large surface area, high strength, excellent decolorization, and efficient COD reduction. Our products are sold nationwide and have proven their effectiveness in various industrial wastewater treatment applications. The iron-carbon micro-electrolysis process, combined with oxidation technology, has a long history of use in wastewater treatment. While the micro-electrolysis process is commonly used in industrial wastewater treatment, oxidation technology is typically employed for pre-treatment and disinfection. The integration of these two technologies is still under research in China, but it holds great potential for reducing operational costs. The iron-carbon micro-electrolysis process utilizes electrochemical reactions, redox reactions, and flocculation, making it a reliable and effective solution. It has achieved impressive results in removing COD (45%–70%) and color (65%–90%). Due to its simple operation, ease of use, and outstanding performance, this technology is widely studied and applied in the treatment of electroplating, petrochemical, and pharmaceutical wastewater. Research on its application in tanning and printing and dyeing wastewater is also gaining attention. The availability of cost-effective fillers further expands its applicability. In the past, issues like iron-carbon bed passivation over time could lead to inefficiency and waste. However, the iron-carbon fluidized bed reactor developed domestically has effectively addressed this problem. Puyinworun Environmental Protection Technology Co., Ltd. continues to innovate and improve its micro-electrolysis technology to meet the needs of high-concentration industrial wastewater treatment. The combination of micro-electrolysis with other processes like flocculation, Fenton, electrolysis, and biological beds is an active area of research. Ensuring continuous activity and efficiency of the micro-electrolysis system is key to its success. Since 2005, the catalytically active micro-electrolysis system developed by Puyinworun and research institutes has been in practical use for over six years, with ongoing improvements based on technical and field requirements. Extensive research has been conducted to prevent the "primary battery" effect and enhance overall wastewater treatment efficiency. **Composition Table:** - Iron fine powder ≥75% - Fine coking coal ≥17% - Metal catalyst ≥2% - Activator ≥5% **Specifications:** - Size: 2*2.5cm oblate - Specific gravity: 1:1.1 - Operating pH: 3–4 - Annual loss rate ≤15% - Service life ≥6 years - Packing: 25kg per bag (woven inside) **Note:** Due to limited supply, orders must be placed in advance.
