Abstract:
1. A process for treating fluid comprising, flowback water, produced fluids or petroleum industry wastewater including the steps of: pressurizing a source of fluid with at least one pump discharging into at least one ozone injection apparatus and thereafter injecting about 505 grams/hour of ozone into said fluid flowing through said at least one ozone injection apparatus to form an ozonated fluid; passing said fluid with injected ozone through a flash reactor having flow paths that create areas of severe velocity and pressure changes which reduces the size of the ozone bubbles to nano size; directing the fluid leaving the flash reactor to a hydrodynamic mixing manifold to create hydrodynamic cavitation; directing said fluid from said hydrodynamic mixing manifold into at least one inlet passageway having a converging dynamic nozzle at an outlet of said at least one inlet passageway and into a main reactor; said reactor having a plurality of ultrasonic transducers, a plurality of anodes and a plurality of cathodes; energizing said plurality of ultrasonic transducers within said main reactor to generate acoustic cavitation within said ozonated fluid; energizing said plurality of anodes and cathodes within said main reactor to create an electrical potential within said main reactor to facilitate precipitation of crystals; conveying the fluid exiting the main reactor through an outlet segment to at least one outlet line; whereby scale formation within the fluid is reduced, bacteria within the fluid is destroyed, and heavy metals within the fluid are oxidized.
