Elgressy Efficient and Reliable Removal of Contaminating Agents from Water Elgressy Electro Oxidation – EEO In any water system, contaminants are a constant problem. Contaminants include bacteria, sludge, pesticides, oil and color. Treating contaminants usually requires a different method for each contaminating agent. Therefore, prevention and treatment of contaminants increase operational and maintenance costs. Prevention and correction Until now, each contaminant in your water system demanded a different treatment module. Elressy’s EEO system supplies a comprehensive treatment regime for a wide range of contaminating agents in one, unique package. Off the shelf system The EEO System connects externally to your existing water system and requires no complicated installation procedures or alterations to your existing system. This represents a significant saving in installation and maintenance costs. EEO – One System with Numerous Benefits

  • Environmentally friendly
  • The EEO process is free of harmful chemicals and harmless to the
  • environment and humans.
  • Reduce sludge volume
  • The EEO system significantly reduces water system sludge and silt buildup.
  • Process multiple contaminants
  • A single EEO system processes a wide range of contaminants, other
  • technologies would have needed a separate system for each contaminant.
  • Automatic and controlled
  • The system is fully automatic and provides complete control over
  • water quality.
  • Extended life span
  • The EEO System, by removing contaminants and not using chemicals,
  • extends the life span of water systems.
  • Low Installation costs
  • Because the EEO System is external to your existing system, installation
  • is an easy and cost efficient process.

EEO – How It Works The Elgressy Electro Oxidation system uses unique ceramic plated titanium anodes developed by Elgressy that do not dissolve in the water. When a DC current is passed through the anodes, a reaction occurs and oxygen, ozone, active chlorine, chlorine dioxide and other oxygenation agents are produced. In the area around the cathode a very high PH level is achieved which cause metal ions or calcium carbonate to sink. 

Electrocoagulation and Electro-oxidation water and wastewater treatment – EEC/EEO

Elgressy electrocoagulation and oxidation systems effciently separate and remove contaminants from water and wastewater, without using chemical additives or generating hazardous byproducts.

Revolutionizing water treatment:

EEC/EEO utilize proprietary electrodes and components to substantially remove multiple impurities from water,
wastewater and rivers. These include various heavy metals, metalloids, silica, organics, ammonia, nitrates, nitrites, phosphates, emulsified oils, suspended solids, solid particles, dye, arsenic, radioactive isotopes and even pathogens.

Innovative technology designed to meet your needs

Elgressy custom manufacture the EEC/EEO systems according to the varying concentrations of contaminants and the clients desired result. Factors such as current density, pH, electrode type, retention time, etc. are key factors in determining the system size, shape, metals, surface area and configuration.
Elgressy proprietary electrodes are manufactured to target a specific or broad range of contaminants in water and
offer a high surface area to volume ratio. As a result, ionization effciency of the electrode is superior, making the electrocoagulation process effective, energy efficient and quick.
The EEC/O systems allow for immediate treatment without chemicals, significantly improve operations, reduce overall
treatment costs, and help meet increasing environmental regulations.


  • “industrial grade” – minimal attention and service required.
  • Chemical free – no hazardous byproducts are generated during the process and no chemical additives are required.
  • Low Capital Cost – EEC/O systems generate substantial savings over current operations.
  • Low Operating Cost – Operating costs can be dramatically reduced by smoother operations and elimination of reagent chemicals and polymer consumption.
  • Proprietary components
  • Simple to retrofit
  • Large electrode surface area enables improved reactions
  • Effective for a broad range of impurities with the ability to target specific contaminants
  • Scalable – 1m3/h – 100m3/h
  • Minimal electrode material and energy consumption
  • Simple electrode replacement
  • Peace of Mind – Comply with current and future regulations.
  • Reduced Salts in Effuent-Low or no use of reagents reduces the sodium, sulfates and chlorides in the effuent
  • Lower Sludge Quantities – significantly less sludge is produced resulting in lower disposal costs.
  • Typical EEC EEC removal rates:
