PROBLEM TO BE SOLVED: To provide a small-scale water treatment apparatus allowing use of purified water at any time, miniaturization and space saving.SOLUTION: A water treatment apparatus comprises a water storage tank 4 for storing water to be treated, an ozone generator 6 generating ozone and a water supply pipe 21 taking out water from the storage tank 4, and an in-tank treatment unit 10 is provided within the storage tank 4. The in-tank treatment unit 10 is arranged in the lower part of a water inlet of the storage tank 4 and has, in a housing case 11, a first filter 13, an upper aeration chamber 12 and a lower aeration chamber 14 arranged in the upstream and/or the downstream of the first filter 13 and supplying ozone generated by the ozone generator 6. Since the water supplied to the storage tank 4 is first water-treated by the first filter 13 arranged in the storage tank 4 and ozone and thus stays within the storage tank 4, leading to effects of miniaturization and space saving. |
