Abstract:
Electrochemical Ozone Generator for In Situ Sterilization of Potable Water and Wastewater
The electrochemical ozone generator (EOG) can generate and dispense ozone (O3) to
sterilize potable water and wastewaters. Ozone is generated by electrochemically
oxidizing water at ambient temperature using no expendables or coolant and little
power. The EOG is unique because it contains no hazardous materials; it does not
contain the lead oxide (PbO2)electrodes or acidic electrolytes used in other electrochemical
O3 generators. Other advantages include the fact that O3 sterilizes more effectively
than most other biocides. Ozone does not degrade the taste of potable water or form
halogenated organics. Unlike solid biocides such as oxone, ozone can be dispensed
easily and accurately. The amount of O3 dispensed can be readily controlled by adjusting
the current to the EOG. The EOG contains no biocide when it is not operating, so
transportation and maintenance procedures are simple and safe, even in a zero-G environment.
Commercial applications would apply to such uses as water disinfection, accelerated
ozone testing hardware, organic contamination removal, and odor elimination.
