Abstract
A disk is placed into a sonication cleaning tank containing a liquid. A first flow rate and a first sonication power are applied to the liquid to clean the disk. An opacity count is generated indicative of contaminants and/or bubbles in the liquid. Based at least in part on the opacity count, a second flow rate and a second sonication power are then applied to the liquid.
