Method of removing ozone remaining in water
The present invention provides a method of removing ozone remaining in water by separating residual ozone which remains in water after ozone is mixed in the water and kills microorganisms in the water including the steps of storing water containing the residual ozone in a pressure tank, supplying the pressure tank with compressed air, generating coarse bubbles larger than the residual ozone existing in water in the form of micro bubbles in pressurized condition, making the residual ozone in the form of micro bubbles adhere to the coarse bubbles, separating the residual ozone from water as the coarse bubbles go up, and discharging the micro bubbles from the pressure tank.Accordingly, the present invention provides a method of removing ozone remaining in water to remove ozone remaining in water inexpensively and efficiently.
