Abstract
In an aeration apparatus and method for producing ultrapure water, a device for vigorously mixing an aeration gas with untreated water is attached to a water pipe through which the water is fed to a reaction tank. The device vigorously mixes the aeration gas with the untreated water in the water pipe before the water reaches the reaction tank. The reaction tank can be smaller, an aeration system for producing ultrapure water can be simpler, and the efficiency of the aeration system can be improved.
