| Outline of Final Research Achievements |
Purpose of this research is to build technology on purification of water with large volume using one-path treatment. Especially water cavitation and discharge plasma were used simultaneously for purification in this research.
Escherichia coli whose initial number density was 2×1015 m-3 was used as a specimen for testing. In our experiments, 5 pair of electrodes was used, and a sterilization ratio of about 83 %, 97 % were obtained at a treatment time of 6, 18 seconds, respectively. A treatment time of 6 seconds corresponds to one-path treatment. From the results, it seems that more than 90 % of sterilization ratio is obtained at 15 pair of electrodes.
