Abstract
A cavitation assembly for purification of drinking water includes a generally cylindrically-shaped open-ended tube for flow of water therethrough, the tube comprising a transducer for converting electrical energy to acoustic energy and transmitting ultrasound through the water in the tube to induce cavitation in the water in the tube. A water moving means flows the water through the tube, and an electrical power source provides electrical power to the tube. The cavitation inactivates microorganisms in the water.
