| 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: |

| 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.
