Project Title:

Novel Electrochemical Ozone Generator

for Disinfection of Spacecraft Water

Technical Abstract (Limit 200 words)

Development of an advanced electrochemical ozone

generator for evolution of ozone directly into water

streams to be treated is proposed for water

reclamation applications on long-duration space

missions. The primary innovation is development of

a biologically inert anode catalyst to replace the

lead dioxide presently used, eliminating the

possibility of lead contamination. The

electrochemical ozone generator will be compact,

lightweight, easy to use and maintain. The water to

be treated is the only reactant, eliminating the need

for expendable biocides. Possible applications of

the ozone generator include: wastewater treatment,

production and maintenance of potable water, and

sterilization of potable-water systems.

The objectives of the proposed program are to

develop the anode catalyst and anode electrode

structure and demonstrate performance and

stability of this structure. The program will

culminate in demonstration of a breadboard

prototype ozone generator and development of a

system design model.

Potential Commercial Applications (Limit 200 words)

Ozone is a powerful disinfectant, with wide potential

applications for water treatment and sterilization.

Due to the compact size, low cost and ease of use of

the proposed electrochemical ozone generator,

there are a myriad of potential commercial

applications in the dental, medical, pharmaceutical

and food industries for this device. Applications

include sterilizing dental units and dialyzers and

general hospital and laboratory disinfection.

Treatment of drinking and waste waters in homes

and public and private utilities is another potential

application.
