A FLUID TREATMENT UNIT COMPRISING AN ULTRASOUND SOURCE

摘要

The present invention relates to a unit and a method for exposing fluid, typically being a liquid, to treatment. The invention relates in particular to a fluid treatment unit with a flow passage through which fluid may flow while being exposed to radiation emitted from an ultrasound source. The fluid treatment unit further comprises one or more total pressure increasing means for increasing the total pressure of fluid at least locally in the fluid treatment unit and a casing which encapsulates the flow passage and the one or more total pressure increasing means.
