Abstract: Systems and methods for harnessing bubbles generated by an effervescent cleaning tablet, to better clean an object (e.g., jewelry, straw, retainer, dental or orthodontic tray, mouth guard, denture, etc.). The system may include a housing including first and second housing portions, each defining a respective cavity. The first housing portion may be configured to hold the cleaning tablet, while the second cavity may hold or at least attach to the object being cleaned (e.g., hold a ring or other piece of jewelry, a retainer, orthodontic or dental tray, mouth guard, denture, etc.). In the case of a reusable straw, the straw may attach over the second housing cavity. In any case, the bubbles generated by the tablet are forced to flow over the object or surface to be cleaned. Such forced pathway of the bubbles causes them to impart mechanical/kinetic cleansing action to the surface of the object being cleaned.

Abstract: A vertically oriented vessel has a swirl plate spiraling around its inner wall surface. A nozzle injects unclean liquid onto the lower surface of the swirl plate for deflection of liquid down towards the bottom of the vessel to generate a liquid vortex flowing causing particulates to precipitate. Above the swirl plate, a preferably cylindrical filter element that filters out particulates is cleaned periodically The filter rotates on a shaft so a high pressure sprays of clean process liquid from an array of nozzles juxtaposed with the filter cleans the filter surface as particulates are flushed from the vessel.
