ABSTRACT:
An improved filtration system comprises a vessel divided into a concentrate chamber and a permeate chamber by a permeable septum. An ultrasonic wave generator is mounted to the vessel and positioned to direct ultrasonic waves through both the permeate contained in the permeate chamber and the permeable septum. A circulator such as a pump or agitator is operably associated with the concentrate chamber to provide a shearing force on the surface of the permeable septum. A vessel inlet port allows concentrate to flow into the concentrate chamber and a permeate outlet port allows permeate to be withdrawn.
