At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to demystifying the advanced technologies that power efficient industrial wastewater treatment. One such technology that has revolutionized the field is the iron-carbon micro-electrolysis filler. Understanding its underlying scientific principles is crucial for appreciating its effectiveness in tackling complex wastewater challenges.

The fundamental mechanism of iron-carbon micro-electrolysis is based on creating a galvanic cell within the wastewater. This is achieved by combining iron (acting as the anode) and carbon (acting as the cathode) materials, often with specific activators and catalysts, in a structured filler. When introduced into wastewater, particularly under acidic conditions, the iron begins to oxidize, releasing Fe2+ ions and electrons. These electrons then travel to the carbon material, where they react with protons and dissolved oxygen, producing hydrogen gas and reactive oxygen species like hydroxyl radicals (•OH).

These hydroxyl radicals are incredibly powerful oxidizing agents. They are capable of breaking down complex organic molecules into simpler, less harmful substances. This process is particularly effective for recalcitrant organic compounds that are resistant to conventional biological treatment methods. The enhanced Fenton process, which utilizes Fe2+ in conjunction with hydrogen peroxide (though the filler itself can generate some oxidizing agents), is significantly amplified by the presence of the iron-carbon filler. This synergy allows for a more potent oxidation of pollutants, leading to a marked increase in the COD removal rate, often exceeding 10% improvement. This is a key advantage for any company looking to buy these advanced materials.

Beyond direct oxidation, the Fe2+ and Fe3+ ions generated during the micro-electrolysis process act as excellent flocculants. As these ions react with water, they form hydroxide precipitates. These precipitates have a high surface area and a strong tendency to adsorb and entrap suspended solids, colloidal particles, and even some dissolved heavy metal ions present in the wastewater. This adsorption and flocculation mechanism effectively removes a significant portion of pollutants, further contributing to the overall purification of the water and providing a more stable and lasting treatment effect.

The advantages of this scientific approach are clear: reduced reliance on external power, efficient degradation of refractory organics, and the combined benefits of oxidation and flocculation. NINGBO INNO PHARMCHEM CO.,LTD. leverages this science to provide solutions that not only meet but exceed industry standards for wastewater treatment, offering a truly advanced chemical water treatment approach.
