NOVELTY - The method for processing wastewater into usable water, comprises receiving a supply of wastewater, passing the wastewater into a refractory vessel (12) having a plasma heat generator (14), increasing a temperature of the wastewater to a predetermined temperature using the heat generator for a predetermined amount of time to produce heated exhaust gases, which include a product gas or water vapor, separating the product gas and water vapor using a scrubber, and condensing the water vapor to produce usable water. The refractory vessel defines a heat processing zone.    USE - The method is useful for processing wastewater into usable water using a plasma generator, where the waste water contains human waste and other harmful contaminants such as hazardous heavy metals, organic poisons, microbiological infective organisms, pharmaceuticals, medications and hormones.    ADVANTAGE - The method is capable of simply, efficiently and rapidly processing the wastewater into usable water with high purity using the plasma generator.    DETAILED DESCRIPTION - The method for processing wastewater into usable water, comprises receiving a supply of wastewater, passing the wastewater into a refractory vessel (12) having a plasma heat generator (14), increasing a temperature of the wastewater to a predetermined temperature using the heat generator for a predetermined amount of time to produce heated exhaust gases, which include a product gas or water vapor, separating the product gas and water vapor using a scrubber, and condensing the water vapor to produce usable water. The refractory vessel defines a heat processing zone, where the wastewater is exposed to the heat processing zone. A portion of the wastewater is treated in a pretreatment phase (16) or a primary treatment phase (18) to produce an effluent, which is processed into usable water by passing the wastewater into the vessel. The effluent is mixed with the wastewater upon entering the refractory vessel and then the effluent keeps in motion as the heat generator increases the temperature of the effluent to the predetermined temperature. A secondary treatment phase (20) including aeration and clarification of effluent fed from the primary treatment phase is provided for treating the wastewater. The effluent from the primary treatment phase is passed through a membrane bioreactor in the secondary treatment phase to produce sludge. The sludge is processed with a dehydration process in a solid waste plasma generator or an independent plasma generator refractory vessel. A gas turbine, a steam turbine and a heat exchanger with first and second sides are provided in downstream of the refractory vessel to produce electricity. The heat is created with the separated product gas to generate steam from the usable water. The heated exhaust gas is passed through the first side of the heat exchanger and then the usable water is passed through the second side of the heat exchanger, where sufficient heat is transferred from the heated exhaust gas to the useable water in the heat exchanger to convert the usable water to steam. The steam is passed through the steam turbine to produce the electricity. The steam exhausted from the steam turbine increases temperature of the wastewater passing into the refractory vessel. An INDEPENDENT CLAIM is included for a system for processing wastewater into usable water.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a wastewater treatment system.
