Water treatment method and water treatment device |
摘要 |
Embodiments of the invention provide a water treatment method and water treatment device capable of automatically tracking the frequency of ultrasonic waves and automatically controlling their amplitude such that optimal cavitation is generated. In one embodiment, a water treatment method of sterilizing water containing microbes comprises supplying ultrasonic vibration to the water to be treated by driving and controlling a transducer of a sterilization cell using a signal; detecting an amplitude of the transducer and a frequency of the signal applied to the transducer; and controlling the amplitude and a vibration frequency of the transducer to target values in accordance with the detected transducer amplitude and the detected signal frequency.
