Applications of high voltage power supplies in the purification of water
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.
