Abstract:

The development and preliminary characterization of an electrolytic technique for destruction of microorganisms in potable and waste water were successfully completed. The technique employs low level cyclic voltages at chemically inert electrodes to pass an alternating current through the process water. The program was directed toward a expanding the design of the electrochemical biocide reactor, b determining the engineering parameters which affect process effectiveness and efficiency and establishing hypotheses for the microorganism kill mechanisms, and c preparing recommendations for scaling the process to both United States Army Medical Research and Development Command USAMRDC and the National Aeronautics and Space Administration NASA requirements. The report describes the experimental hardware, the methodology and microorganism kill results with three bacteria Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae, two viruses Polio I and Coxsacki B, one yeast Saccharomyces cerevisiae, and the normal flora of microorganisms found in domestic raw settled sewage. A literature search was conducted on prior research and development efforts related to the electrolytic disinfection of water and waste water.
