Patent ID: 8858892

Claim:
A liquid treatment system comprising: a housing defining an interior space, the housing having at least one inlet port for receiving liquid into the interior space of the housing and at least one outlet port for allowing liquid to exit the interior space of the housing, the outlet port being spaced from the inlet port so that liquid flows in a flow path through the interior space of the housing from the inlet port to the outlet port; an ultrasonic waveguide assembly disposed within the interior space of the housing and comprising an ultrasonic horn disposed at least in part intermediate the inlet port and the outlet port of the housing and aligned coaxially with the housing, the ultrasonic horn being operable at an ultrasonic frequency to ultrasonically energize liquid flowing from the inlet port to the outlet port within the housing, wherein the ultrasonic horn has an outer surface and a plurality of discrete agitating members extending at least in part transversely outward from the outer surface, and wherein the housing has an inlet end and the ultrasonic waveguide assembly extends longitudinally from the inlet end of the housing into the interior space of the housing; a baffle assembly suitably disposed within the interior space of the housing and in a transversely opposed relationship with the ultrasonic horn and the flow path; and an ultraviolet light source for emitting ultraviolet light into the interior space of the housing to treat liquid flowing from the inlet port to the outlet port.
