1. An apparatus for treating a liquid comprising:
outer, intermediate, and inner cylinders positioned concentrically with respect to each other, the outer, intermediate, and inner cylinders defining an outer annular chamber, an intermediate chamber, and an inner, central chamber; an outer feed channel supplying liquid being treated to the outer annular chamber; first and second flow generators having a unidirectional flow channel extending therethrough from adjacent an upstream end to adjacent a downstream end thereof mounted in the intermediate cylinder with the upstream ends of the flow generators communicating with the annular outer chamber to receive liquid therefrom and the downstream ends thereof communicating with the inner, central chamber; the first flow generator having an outlet in the downstream end for generating a first flow stream of the liquid being treated, wherein the first flow generator is a cavitation generator adapted to generate a first flow stream including multiple cavitation bubbles or wherein the first flow generator is a nozzle adapted to generate a first flow stream substantially devoid of cavitation bubbles; the second flow generator having an outlet in the downstream end for generating a second flow stream of the liquid being treated; a reaction chamber positioned in the inner, central chamber and spaced apart from and positioned in proximity to the outlet of the first flow generator, the reaction chamber having an external wall including a cavity formed therein, the cavity having a first inlet situated in a confronting relationship with the outlet so that the cavity receives the first flow stream directly from the outlet of the first flow generator and wherein the received first flow stream is redirected in the cavity back towards the first inlet and out the cavity; and a central, outwardly-flowing channel receiving liquid treated by the first and second flow generators.
