Abstract
A system for performing ozone water treatment comprises a voltage supply circuit and a plasma eductor reactor. The voltage supply circuit includes an H-bridge controller and driver, a transformer, and an output port. The H-bridge controller and driver are configured to switch the electrical polarity of a pair of terminals. A primary of the transformer is connected to the H-bridge driver and controller. A secondary of the transformer connects in parallel with a first capacitor and in series with an inductor and a second capacitor. The output port connects in parallel with the second capacitor. The plasma eductor reactor includes an electric field generator, a flow spreader, and a diffuser. The electric field generator includes a pair of electrodes that generate an electric field. The flow spreader supplies a stream of oxygen. The diffuser supplies a stream of water. The streams of water and oxygen pass through the electric field.
