Abstract:
A method for remediating contaminated liquid comprising the steps of passing at least a portion of said contaminated liquid through one or more jet nozzles to induce fluid jet cavitation in said liquid, wherein said fluid jet cavitation is sufficiently intense to cause decomposition or destruction of contaminants in said liquid, each of the one or more jet nozzles having an entry portion, a central portion, an interior surface and a longitudinal centerline therethrough, said entry portion characterized by an interior surface which tapers sharply to a restricted opening in order to cause a rapid change in direction of the flow of contaminated liquid toward the longitudinal centerline of the nozzle thereby forming a first shear zone within said central portion between the fluid jetting toward the longitudinal centerline and relatively static fluid adjacent the interior surface of said central portion.
