The electrocoagulation system is a wastewater treatment process that utilizes metal hydroxide produced by a soluble metal anode during flocculation to remove contaminants from water. The anode material typically uses aluminum, iron, and other readily available, inexpensive metals.

Electrochemical reaction: Fe→Fe2++2e

Anodizing reaction: 2OH-→2[O]+2e→O2+2e. The nascent oxygen [O] has strong oxidation function comparable to UV, H2O2 and O3.

Cathode reduction: 2H++2e→2[H]→H2. Nascent hydrogen can break bonds, COD, chromophore functional groups and multi-chain health.

These oxidation and reduction functions occur continuously on the plates.

1. Wide power supply adaptability: 220V-480VAC range available
2. Safe and convenient: Embedded isolated voltage circuit ensures electrical safety with multiple protection features (phase loss, overload, overcurrent, overvoltage, zero voltage, etc.)
3. Automatic control: Detects ion state in water to adjust current and voltage
4. Energy efficient: Fe(OH)2 and Fe(OH)3 serve as excellent coagulants, eliminating need for polymer additives
