ABSTRACT:
The apparatus for liquid sterilization by high-pressure dynamic cavitation includes a fluid passage through which the continuous flow of liquid passes, wherein the fluid passage is defined by a closed cylindrical chamber having a side wall and first and second opposing ends. The chamber has an inlet and an outlet through which the continuous flow of liquid enters and exits the chamber, the inlet being tangential to the chamber axis and adjacent to the first end to provide tangential flow within the chamber and to cause the liquid flow to be deflected at the first and second opposing ends two or more times for increasing sterilization time of the liquid before exiting the outlet axially disposed on the second end. One or more projections protruding from the interior side wall of the chamber create a high-pressure drop in the flow behind the one or more projections and thereby create high-pressure dynamic cavitation for effective sterilization.
