Abstract: A system and method for treatment of a wastewater fluid is described. The system includes a gas supply system to provide a process gas into the wastewater fluid, a pulsed electrical-power generator to generate high electrical voltage pulses and a reactor apparatus pneumatically coupled to the gas supply system, and electrically coupled to the pulsed electrical-power generator. The reactor apparatus is configured to produce a plurality of gas microbubbles of the process gas injected into the wastewater fluid supplied into the reactor apparatus for the treatment, and to apply the high electrical voltage pulses generated by the pulsed electrical-power generator to said plurality of the microbubbles. The high electrical voltage pulses have energy sufficient to create a plasma glow discharge within the plurality of the microbubbles, and in an interface of the microbubbles with the wastewater fluid.

Abstract: A wastewater plant and method for treatment of wastewater sludge or other wastewater fluids are described. The wastewater plant utilizes an electrical discharge system configured for receiving a wastewater fluid, and generating a transient voltage and arcing electric current pulse through the received wastewater fluid to create an electro-hydraulic shock wave within the wastewater fluid accompanied by a high electric field, intensive heat and light radiation.
