What is electro-oxidation?Use of electricity (DC) to coagulate and settle as sludge the suspended solids and oxidize organic matter.
ecowater
What can EO do?• Coagulate suspended solids & settle into sludge
• Oxidize organics and reduce soluble COD
• Destroy pathogens
ecowater
How does EO work?Key Reactions
• Oxidation / Reduction• pH change• Sweep coagulation• Charge neutralization• Floatation• Electrophoresis• Disinfection

How does EO work?Example of electro-coagulation, Flocculation and floatation.
The principle of this reaction:
1. Charge Neutralization / coagulation: (+ve charged ions react with negative charged ions. Reaction time: 0.2 seconds)
2. Al(s) – e + H2O Al(OH)2+ + Al(OH)+2
+ Al7(OH)4+17
3. Sweep Coagulation / Flocculation: (Al complexes adsorb on to colloidal particles. Reaction time: 7 seconds
4. Al(OH)2+ + Al(OH)+2
+ Al7(OH)4+17 Al(OH)3(s)

COD Reduction with EO
1. Removes COD by 70-80% in a single step
2. BOD is also reduced proportionally
3. Breaks long molecules & converts tough to degrade molecules to bio-degradable
4. Destroys pathogens with electric field

SOOO…
YOU CAN USE TREATED WATER
FOR ANY APPLICATION
