Abstract
The invention provides a method for reducing aquatic organic contamination present in a volume of water, the method comprising: pumping the water from an open body of water contaminated with aquatic organisms through a reactor unit including a conduit system of varying diameter such that the pressure head in the water is caused to fall to a level below atmospheric pressure, and so to cavitate, at a point in the system by increasing the velocity head of the water at that point. The invention also includes apparatus for use in the method.

A method for reducing aquatic organic contamination present in a volume of water, comprising:
- pumping the water from an open body of water contaminated with aquatic organisms through an elongate conduit system, the water having a volumetric flow rate that is the same at all points in the system, and having, at any point in the system, a pressure head and a velocity head;
- and directing the water into the tank;
- and characterized by pumping the water through a reactor unit including a conduit system of varying diameter such that the pressure head in the water is caused to fall to a level below atmospheric pressure, and so to cavitate, at a first point in the system by increasing the velocity head of the water at the first point.
An apparatus for reducing aquatic organisms in a body of water, comprising:
- a reactor having an elongate conduit system having an upstream end and a downstream end, and being configured to permit the water to flow therein at a constant volumetric rate, characterized in the conduit system defining portions that comprise:
- a first tapered portion having a generally frusto-conical shape, and having a downstream end defining a first opening having a first diameter, and an upstream end defining a second opening having a second diameter larger than the first diameter;
- and a first reactor portion having a generally cylindrical shape with a third diameter, larger than the first diameter, the first reactor portion being connected to the downstream end of the first tapered portion by a radially disposed connector, such that the diameter of the conduit system immediately increases abruptly downstream of the first opening in the tapered portion;
- wherein the first diameter is sized to initiate cavitation in water flowing downstream through the conduit system
