Abstract:
1. A method of disinfecting a fluid, comprising: placing the fluid between an inward-facing first electrically conductive cylindrical body and an outward-facing electrically conductive second cylindrical body disposed within first cylindrical body, in mutually facing parallel and coaxial relation thereto, and spaced apart therefrom to define a fluid-occupiable cavity; and electrically energizing said first cylindrical body and said second cylindrical body, producing therebetween an electric field, said field comprising a waveform approximating a series of alternating square wave pulses of opposite polarity, said pulses having a maximum absolute value of approximately 60 volts per centimeter, a complete cycle of said waveform, comprising a first pulse and a succeeding pulse of opposite polarity, recurring with a frequency of between 2 kHz and 5 kHz.
