An external power source is coupled through a pulse forming network to the electrodes. The network is impedance matched to the impedance of the plasma arc generated between the electrodes to provide a high power pulse to the electrodes. The establishment of the plasma produces an extremely high pressure shock wave, u.v. radiation fringing on X-ray and electrohydraulic pressurization to alter the characteristics of the liquid therein.Field of SearchUsing direct contact with electrical or electromagnetic radiationIn atmosphere other than air Arc or spark discharge means With preparatory or product-treating means With current control means Discharge of treated material With separator inlet control WITH TIME CONTROL Of additional fluid AUTOMATIC CONTROL ELECTRICAL INSULATING OR ELECTRICITY DISCHARGING With storage unit With pump, gas pressure or vacuum source Level sensing Utilizing electrical or wave energy (directly applied to liquid or material being treated) WITH MEANS TO ADD TREATING MATERIAL Electrostatic field or electrical discharge |
