Waste water treatment

Waste water is mostly treated by costly and polluting chemicals.
NO CHEMICALS needed with Elgressy Electrocoagulation and oxidation. EEC and EEO are in most cases the most effective and economical solution, chemical free and re-usable water after treatment.

NON CHEMICAL 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:
