Abstract

A liquid treatment chamber having an elongate housing through which liquid flows longitudinally from an inlet port to an outlet port thereof is disclosed. An elongate ultrasonic waveguide assembly extends within the housing and is operable at a predetermined ultrasonic frequency and a predetermined electrode potential to ultrasonically energize and electrolyze liquid within the housing. An elongate ultrasonic horn of the waveguide assembly is disposed at least in part intermediate the inlet and outlet ports, and has a plurality of discrete agitating members in contact with and extending transversely outward from the horn intermediate the inlet and outlet ports in longitudinally spaced relationship with each other. The horn and agitating members are constructed and arranged for dynamic motion of the agitating members relative to the horn at the predetermined frequency and to operate in an ultrasonic cavitation mode of the agitating members corresponding to the predetermined frequency and the liquid being treated in the chamber.
