METHOD FOR PRODUCING LIQUID HAVING SUPERSATURATED OXYGEN

摘要

PURPOSE: An oxonized liquid having supersaturated oxygen is provided, which restrains the growth of bacteria, by producing an oxygenated and ozonized liquid by making the generated ozone pass through a contact tank and making the produced liquid pass through a contact loop of an inline supersonic mixer. CONSTITUTION: A mixture(12) of ozone and pure oxygen is added to the bottom part of an ozone contact tank(16) and water(14) is guided to the upper part of the tank(16). The ozonized/oxygenated mixture(18) is discharged from the lower part of the tank(16) and made to pass through a seven-stage centrifugal pump(20) to produce a mixture(22) having supersaturated oxygen. The mixture(22) is then made to pass through a flow meter(24) and the contact loop of the inline supersonic mixer. The liquid(50) is discharged as the liquid(46) having supersaturated oxygen for filling work.
