Industrial Electrocoagulation System 5m3/h for Wastewater Treatment

The Electrocoagulation (EC) system is an advanced wastewater treatment process that utilizes metal hydroxide produced by soluble metal anodes during flocculation to effectively remove contaminants from water. The system typically employs aluminum, iron, and other readily available, cost-effective metals as anode materials.

The electrocoagulation process involves three key electrochemical reactions:

• Electrochemical reaction: Fe → Fe²⁺ + 2e⁻
• Anodizing reaction: 2OH⁻ → 2[O] + 2e⁻ → O₂ + 2e⁻ (nascent oxygen [O] provides strong oxidation comparable to UV, H₂O₂, and O₃)
• Cathode reduction: 2H⁺ + 2e⁻ → 2[H] → H₂ (nascent hydrogen breaks chemical bonds, COD, chromophore functional groups, and multi-chain compounds)

These oxidation and reduction reactions occur continuously on the electrode plates.

• Wide power adaptability: Operates within 220V-480VAC range with no power phase sequence requirements
• Enhanced safety: Embedded isolated voltage circuit with comprehensive protection (phase loss, overload, overcurrent, overvoltage, zero voltage)
• European terminals: Detachable control signal terminals allow easy rewiring during maintenance
• Automatic control: Continuously monitors and adjusts current/voltage based on water ion state
• Energy efficient: Utilizes naturally produced Fe(OH)₂ and Fe(OH)₃ coagulants without requiring polymer additives
