Electrocatalytic Oxidation (ECO) Technology

Electrocatalytic, Inc. was a pioneer in the field of electrocatalytic oxidation (ECO) technology for water treatment. This technology utilizes electrically charged electrodes to break down harmful contaminants in water, effectively removing pollutants without the use of harsh chemicals.

How ECO Works:

• Electrodes: The core of ECO technology lies in specialized electrodes made of materials like platinum, titanium dioxide, or boron-doped diamond. These electrodes act as catalysts, promoting the oxidation of contaminants at the electrode surface.
• Electrolysis: When an electric current is applied to the electrodes, it initiates electrolysis, splitting water molecules into hydrogen and oxygen ions.
• Oxidation: The generated oxygen ions react with organic pollutants at the anode (positive electrode) to break them down into less harmful byproducts, often carbon dioxide and water.
• Reduction: At the cathode (negative electrode), reduction reactions may occur, further contributing to the degradation of certain contaminants.

Advantages of ECO:

• Environmentally Friendly: ECO eliminates the need for hazardous chemicals commonly used in traditional water treatment methods.
• Effective for Diverse Pollutants: ECO can effectively degrade a wide range of pollutants, including organic compounds, pesticides, pharmaceuticals, and heavy metals.
• High Efficiency: ECO processes offer high treatment efficiency, leading to significant reductions in contaminant levels.
• On-Site Applications: ECO technology is suitable for both centralized and decentralized water treatment applications, including municipal water treatment plants, industrial wastewater treatment facilities, and residential water purification systems.

Variations of ECO:

• Direct Electrocatalytic Oxidation (DECO): Direct oxidation of pollutants at the electrode surface.
• Indirect Electrocatalytic Oxidation (IECO): Mediated oxidation by electrochemically generated oxidizing species, such as hydroxyl radicals.

Electrocatalytic, Inc. played a crucial role in developing and refining ECO technology, laying the foundation for its widespread application in the water treatment industry.
