Fluid jet cavitation method and system for efficient decontamination of liquids

An apparatus for the remediation of contaminated liquids by the induction of jet cavitation in said liquid comprising:

• a pump connected to a source of contaminated liquid,
• means for communicating with the pump with an entry chamber for receiving a flow of contaminated liquid, and
• one or more jet nozzles wherein each of the one or more jet nozzles, having an entry portion, a central portion, an interior surface, a longitudinal centerline therethrough, and a exit port, 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 shear within said central portion between the fluid jetting toward the longitudinal centerline and relatively static fluid adjacent the interior surface of said central portion, and each nozzle is arrayed in said entry chamber in a manner which allows said contaminated liquid to flow from said entry chamber into the entry portion of the nozzle and to exit the exit port of the nozzle, inducing jet cavitation in said liquid wherein said jet cavitation is sufficiently intense to cause decomposition or destruction of contaminants in said liquid.
