Systems and methods for non-thermal plasma over liquid direct ion injection

A system for performing ozone treatment, the system comprising:

• a voltage supply circuit including:
• an H-bridge driver configured to switch electrical polarity of a pair of terminals,
• an H-bridge controller configured to send a control signal to the H-bridge driver to control the switching of the electrical polarity,
• a transformer including a primary connected to the terminals of the H-bridge driver and a secondary,
• an impedance matching network connected in parallel with the secondary,
• an inductor connected in series with the secondary,
• an output port connected to at least one terminal of the secondary for delivering a voltage to a load, and
• a phase sensor to sense a phase of current through components connected to the secondary and an auto tune signal generator configured to send a signal to the H-bridge controller to set a phase value of the control signal to adjust the phase of the H-bridge driver to approximate a resonant frequency of the secondary;
• and
• a plasma eductor reactor including:
• a housing including a reactor chamber internal to the housing,
• an electric field generator including a first electrode and a spaced apart second electrode configured to generate an electric field therebetween, the first and second electrodes connected to the output port of the voltage supply circuit, each having an annular shape of roughly the same size and together producing a cylindrical electrical field,
• a flow spreader to supply a stream of oxygen to the reactor chamber, the flow spreader positioned within the reactor chamber concentrically with the first and second electrodes, and
• a diffuser to supply a stream of liquid to the reactor chamber, the diffuser positioned within the reactor chamber concentrically with the first and second electrodes and the flow spreader,
• wherein the stream of liquid and the stream of oxygen flow adjacent one another radially outward from a center of the reactor chamber and pass through the electric field.
