Abstract:

An alternate disinfecting process to chemical agents, heat and radiation in an aqueous media has been studied. The process is called an Electrochemical Biocide and employs cyclic, low level voltages at chemically-inert electrodes to pass alternating current through water and, in the process, destroy microorganisms present. The reported experimental data is the result of an extension to a process feasibility research and development program. The report describes the experimental hardware, methodology and microorganism kill results for the total flora in raw, settled sewage and for Escherichia coli in unbuffered test water. The current program emphasized gaining a better understanding of the process kill mechanisms and increasing the process efficiency. Instrumentation was used to control and monitor the frequency, waveform and amplitude of the applied electrical signals.
