Abstract
The use of high frequency or ultrasonic vibrations transmitted into and through a suitable medium can increase solution effectiveness. This means that in a continuous cleaning process, ultrasonic activation of the cleaning solution can increase productivity without increasing the energy requirement. Basic principles of ultrasonic activation will be discussed with attention paid to the energy saving aspects.
