1. A process for producing ozone-containing sterilizing water continuously, comprising the steps of:

  • introducing raw water and ozone gas, together, into a compression tank to produce a bubble phase mixture, said raw water being moved at a faster speed at a predetermined passage to induce a pressure drop, said ozone gas being drawn into the compression tank by the pressure drop;

    charging said bubble phase mixture into any one of compartments of the compression tank, and pressurizing the mixture in the charged compartment to give ozone-containing sterilizing water, said compartments being sealably separated by a movable partition within the compression tank;

    moving the partition to reduce the volume of the charged compartment to discharge the ozone-containing sterilizing water while another of said compartments is expanded in volume through being charged with said bubble phase mixture; and

    repeating the above steps.
