Claim:
1. A device for treating at least one compound in a liquid, comprising: a first element having a radial face and an axial liquid-inlet orifice, and a second element having a radial face, in which said radial faces are arranged opposite each other and parallel, so as to form a radial cavitation chamber having a peripheral outlet opening, the first and second elements have bearing faces which bear on each other such that said radial cavitation chamber has one thickness between said radial and parallel faces of the first and second elements, said axial inlet orifice of the first element opening out into a central part of the cavitation chamber opposite said radial face of the second element and the peripheral outlet opening being distributed at a periphery of the radial cavitation chamber; said thickness of said cavitation chamber, between said radial and parallel faces, has a value comprising between 0.1 and 0.25 times a diameter of said axial inlet orifice, a distance between an axis through a center of the axial inlet orifice and said peripheral opening of said cavitation chamber being more than twice the diameter of said axial inlet orifice; and a secondary chamber communicating with the said peripheral outlet opening of the cavitation chamber, the secondary chamber having an outlet orifice, whereby the liquid is supplied axially through the axial inlet orifice and is deflected in the central inlet part and flows into said radial cavitation chamber in various radial directions toward the peripheral outlet opening and then in the secondary chamber towards the outlet orifice; and whereby, a ratio between a pressure upstream of said radial cavitation chamber and the pressure downstream of the radial cavitation chamber having a value comprising between 1.5 and 6, flow conditions of the liquid by themselves generate cavitation bubbles or pockets in the first part of this flow, around the axial inlet orifice, and the cavitation bubbles or pockets implode before they reach the peripheral outlet opening, in order to treat said compound at least partially.
