Disclosed are systems and methods for mixing a gas-free liquid oxidant with a process liquid to form a homogeneous and gas-free mixture with minimized degassing. The mixing system comprises an injection device, integrating with a pipe through which a process liquid flows, configured and adapted to inject a gas-free liquid oxidant into the process liquid, and a mixer, fluidly connected to the pipe and the injection device, configured and adapted to mix the process liquid and the gas-free liquid oxidant therein to form a homogeneous and gas-free mixture of the process liquid and the gas-free liquid oxidant with minimal degassing. The method comprises the steps of a) injecting the gas-free liquid oxidant into the process liquid, and b) mixing the gas-free liquid oxidant and the process liquid to form the homogeneous and gas-free mixture. The gas-free liquid oxidant is ozone strong water.

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 O-Ogas 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.

Methods for producing high-concentration of dissolved ozone in liquid media

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.
