The present invention discloses a method and apparatus for separating particles and dissolved matter from a produced water fluid stream. Specifically, the present invention includes a first pressure source which transports untreated produced water or contaminated aqueous fluid into a separator annulus with a filter element disposed therein.

A system and method of performing ultrasonic cleaning is disclosed whereby a conventional ultrasonic cleaning bath is augmented via the use of a cleaning target support structure and an optional mechanical isolator whereby the cleaning target is mechanically isolated from the ultrasonic cleaning bath. This isolation permits ultrasonic harmonics which are normally damped (suppressed) in amplitude due to conventional mechanical connections between the bath and the containment vessel to be fully applied to the cleaning target, resulting in substantial reduction in overall cleaning time and an improvement in cleaning efficiency. Various embodiments of the proposed system and method are disclosed, with several being preferred. Namely, the use of a circular floating-ballast to support a glass or plastic beaker used as the containment vessel is preferred as well as the use of a circular floating-ballast to support a plastic bag used as the containment vessel.

This isolation reduces the effective mass of the structure comprising the cleaning target, the containment vessel, and the containment vessel support (ballast means) and permits ultrasonic harmonics to fully affect cleaning with minimal harmonic damping. Consistent cleaning time improvements of 20-80% over conventional prior art basket-type and containment vessel support cover methods has been observed.
