A method and apparatus for conducting sonochemical reactions and processes using in large scales liquid medium volumes is disclosed which passes a hydrodynamic liquid flow at a velocity through a flow through channel internally containing at least one element to produce a local constriction of the hydrodynamic liquid flow. The velocity of the liquid flow in the local constriction is at least 16 m/sec. A hydrodynamic cavitation cavern is created down stream of the local constriction, thereby generating cavitation bubbles. The cavitation bubbles are shifted with the liquid flow to an outlet from the flow through channel and the static pressure of the liquid flow is increased to at least 0.85 kg/cm.sup.2. The cavitation bubbles are then collapsed in the elevated static pressure zone, thereby initiating the sonochemical reactions and processes. At least one element may either be a bluff body which produces a local constriction of the hydrodynamic liquid flow or a baffle which contains at least one transit channel to produce the local constriction of the liquid flow.

[ I claim:] [1.] A method of conducting sonochemical reactions and processes in large scale liquid medium volumes comprising the steps of:passing a hydrodynamic liquid flow at a velocity through a flow-through channel internally containing at least one element, thereby producing a local constriction of the hydrodynamic liquid flow;maintaining the velocity of the hydrodynamic liquid flow in the local constriction of the hydrodynamic liquid flow at a minimum velocity;creating a hydrodynamic cavitation cavern downstream of the local constriction of the hydrodynamic liquid flow, thereby generating cavitation bubbles, the cavitation bubbles shifting with the hydrodynamic liquid flow to an outlet from the flow-through channel, the hydrodynamic liquid flow having a static pressure;increasing the static pressure of the hydrodynamic liquid flow at the outlet from the flow-through channel to a minimum pressure with a hydrodynamic restriction being positioned at the outlet or some distance from the flow-through channel in a pipeline of a local hydraulic resistance, thereby creating an elevated static pressure zone; and,initiating the collapse of the cavitation bubbles in the elevated static pressure zone.
