Abstract: Disclosed are decoupled systems and methods for producing an oxidized liquid. The method comprises the steps of generating an ozone strong water in a mass transfer unit, mixing the ozone strong water with a process liquid in a mixing unit to form a homogeneous and gas-free mixture of the ozone strong water and the process liquid, forwarding the homogeneous and gas-free mixture to a reaction unit, and producing the oxidized liquid in the reaction unit. The method utilizes the acidic feed liquid to generate ozone dissolved in water having a higher concentration at a saturated or nearly saturated concentration compared to prior art processes at atmospheric pressure and neutral or alkaline pH.

Abstract: Disclosed are methods for continuous production of ozone strong water, the methods comprising the steps of injecting an acidification agent into a pressurized feed water to maintain a pH value of the pressurized feed water below 7, diffusing a two-phase mixture of O2-O3 gas and recirculated water into a body of acidic pressurized water to dissolve ozone into the acidic pressurized water. The disclosed methods include simultaneously maintaining a start-up mode in an upper portion of the dissolution column that favors high efficiency of ozone mass transfer into the acidic pressurized water and a steady state mode in a lower portion of the dissolution column that favors a high concentration of dissolved ozone in the acidic pressurized water coexistent in the body of the acidic pressurized water, wherein an ozone concentration gradient is formed along a height of the body of the acidic pressurized water.

Abstract: Disclosed are systems for continuous production of ozone strong water, the systems comprising an injection device that injects an acidification agent into a pressurized feed liquid, a diffuser device that injects ozone into a body of the acidic pressurized feed water, and injection nozzles each controlled by a valve that adjust a flow rate of the ozone strong water discharged from a dissolution column to match a flow rate of the acidic pressurized feed water fed to the dissolution column, thereby maintaining a start-up mode in an upper portion of the dissolution column that favors a high efficiency of ozone mass transfer and a steady-state mode in a lower portion of the dissolution column that favors a high dissolved ozone concentration coexistent in the body of the acidic pressurized liquid, wherein a concentration gradient of dissolved ozone is formed along a height of the body of the acidic pressurized liquid.
