Claims
- 1. A method to disinfect a porous solid medium, comprising the steps of:
- embedding a plurality of electrodes into said porous solid medium;
- applying a plurality of alternating current voltage pulses between said electrodes wherein each of said voltage pulses has a peak voltage of from 10 kilovolts to 200 kilovolts and said plurality of alternating current voltage pulses are of an intensity and duration effective to generate a quantity of ozone in said porous solid medium that is effective to disinfect said porous solid medium.
- 2. The method of claim 1 wherein said duration is between 2 seconds and 5 minutes.
- 3. The method of claim 1 wherein said porous solid medium is selected to be soil.
- 4. The method of claim 3 wherein said soil contains fungi that are destroyed by said method.
- 5. The method of claim 1 wherein the pulse width of the alternating current voltage is between about 0.02 milliseconds and about 0.02 seconds.
- 6. The method of claim 5 wherein said pulse frequency of the alternating current voltage is between about 50 per second and 50,000 per second.
- 7. The method of claim 1 wherein said pulse frequency of the alternating current voltage is between about 50 per second and about 50,000 per second.
