Abstract:
1. A sonication cleaning system comprising: a sonication cleaning tank configured to contain a liquid comprising both contaminants and bubbles; a filter fluidly coupled to the sonication cleaning tank and configured to remove contaminants from at least some of the liquid to produce filtered liquid; at least one liquid particle counter fluidly coupled to the sonication cleaning tank, the at least one liquid particle counter configured to generate a first opacity count indicative of both the contaminants and the bubbles in the liquid and further configured to generate a second opacity count indicative of substantially only the bubbles in the filtered liquid; and a computing device coupled to the at least one liquid particle counter and configured to determine a contaminant count corresponding to an estimated number of contaminants in the liquid based at least in part on the first and second opacity counts.
