High voltage treatment technology has been developed by the authors and has shown promise in its effectiveness in reducing microorganisms found in water supplies. Initial testing on a one litreper- minute (LPM) device found that the high voltage could destroy over 99.9% of the bacteria S. marcescens. The device was scaled up to treat flows of 10 LPM and 33 LPM. A high voltage switch-mode-power-supply (SMPS) was also constructed. This supply has a number of significant advantages over the 50 Hz models. The device was successfully tested on a recirculating system and reduced the numbers of bacteria by over 4-log.
