Apparatus for treating liquids with wave energy from an electrical arc

An apparatus for treating a liquid comprising:

• a pump volute or hydrocyclone head having an inlet and an outlet;
• a throat having a first opening, a second opening and a central axis, wherein the first opening is connected to the outlet of the pump volute or hydrocyclone head;
• a parabolic reflector having a vertex, a focus and an opening at the vertex, wherein the opening is connected to the second opening of the throat such that the vertex and focus are axially aligned with the central axis and the focus is not located within the throat;
• a wave energy source to irradiate the liquid comprising a first electrode within the pump volute or hydrocyclone head that extends through the outlet into the first opening of the throat along the central axis of the throat, and a second electrode extending into the parabolic reflector proximate to the focus wherein the second electrode is spaced apart and axially aligned with first electrode;
• and
• wherein the liquid enters through the inlet of the pump volute or hydrocyclone head and exits through the opening at the vertex of the parabolic reflector.
