This disclosure describes methods, devices, and systems for introducing cavitations into a liquid. In some implementations, the methods and devices allow for small batch processing of a liquid with a transducer, which introduces ultrasonic energy into the liquid causing cavitations. In some instances, the cavitations may fragment or degrade compounds within the liquid and enhance the quality of the liquid. This disclosure also describes methods and systems of introducing cavitations into a liquid via a continuous flow system to process a large quantity of liquid.
