<P>PROBLEM TO BE SOLVED: To provide a sterilization system of a circulation type bath using high output ultrasonic waves where a reduction in sterilization power is not caused by contamination with the lapse of time. <P>SOLUTION: The sterilization system is provided with: a bath 10 filled with bath water 90; a circulation pump 20 for circulating the bath water 90; a free chlorine addition apparatus 30 for chlorine sterilization; a filter 40 for removing solid matter in the bath water 90; an ultrasonic sterilization apparatus 50 for sterilizing the passing bath water 90 by generating ultrasonic waves for sterilization; and a heating apparatus 60 for heating the bath water 90 to a prescribed temperature. An ultrasonic generator in the ultrasonic sterilization apparatus 50 generates ultrasonic waves by a vibration part extending to the inside of a cover in an ultrasonic transmission part, and in the bath water 90 fed from a suction port to the cover in the supersonic originating part, by the impact pressure on shrinkage destruction of bubbles (cavities) generated in the bath water 90 owing to the action of the ultrasonic waves generated by the vibration of the vibration part, the cells of harmful microorganisms such as bacteria and pathogenic protozoa are destroyed so as to be sterilized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
