Overview of Electrolytic Organic Destruction (EOD) Applications
This page discusses applications of EOD technology. EOD technology removes organics from aqueous streams using
electrochemical and chemical oxidation (click here for more information on the EOD Process). For additional information
on EOD including systems, services and economics, simply click on the word or follow the link on the navigation bar to
Products and Services.
Test Results
The links below show results from testing of EOD in various applications at different scales:
General Application Information
The discharge of organic waste into surface water or deep wells is encountering increased regulatory restrictions (BOD,
COD, and others). In addition, even though discharges may meet regulatory limits, there is often additional justification for
reducing such discharges, for example:
Electrochemical oxidation has been shown to be feasible for many organic contaminants. S. Stucki reported laboratory
results for many organic compounds using an electrochemical oxidation index (Journal of Applied Electrochemistry 21
(1991) 99-104, Electrochemical Waste Water Treatment using High Overvoltage Anodes, Part II: Anode Performance and
Applications, S. Stucki et al) .
This index is the oxygen produced in the presence of an organic divided by the oxygen produced without the organic. It
measures the portion of electrons that oxidize the organic. The following table shows the electrochemical oxidation index
(EOI) for a number of organic compounds:

The discharge of organic waste into surface water or deep wells is encountering increased regulatory restrictions (BOD,
COD, and others). In addition, even though discharges may meet regulatory limits, there is often additional justification for
reducing such discharges, for example:
- Improve the public image of a company by reducing discharges of pollutants such as those found on the Toxic
Release Inventory List. - Meet Sustainable Development Objectives
- Reduce EPA documentation requirements.
- Avoid the high present-day cost of drilling and maintaining deep wells and avoid concerns about future liability.
- Recover and recycle valuable resources.
- Alleviate the tendency for organic contaminants to accumulate, thus affecting the efficiency and effectiveness of
chemical processes and, in some instances, accelerating corrosion in closed-loop systems.

EOD can provide an alternative method for organic removal versus biological treatment methods. This is true where the
organic compounds are especially toxic, not treatable by biological organisms (biorefractory) or require a very long time
to be broken down by bacteria. EOD systems can be used as a primary treatment technique or as a complement to a
biological system by converting organic compounds to forms that are more treatable by bacteria.
EOD is also an alternative method for organic removal versus adsorption techniques such as activated carbon where the
disposal or regeneration of the adsorbent is expensive or creates future environmental liability. It is often less expensive
than evaporation and incineration. It can also enhance reverse osmosis and ultrafiltration processes.
EOD systems and technology offered by Spartan Environmental have been demonstrated for different chemical
substrates on the commercial, pilot and laboratory scale. Click on the links at the top of the page to learn about specific
examples where EOD technology has been demonstrated.
