WATER TREATMENT METHOD AND APPARATUS USING HIGHLY CONCENTRATED OZONE

摘要

PROBLEM TO BE SOLVED: To provide a water treatment method and apparatus simpler and more efficient than a conventional technique and especially putting an advantage due to a highly concentrated ozone gas to practical use effectively. SOLUTION: The water treatment apparatus using highly concentrated ozone has a pump (1) for pressurizing water to be treated, a back pressure type ejector (2) for bringing the pressurized water to be treated into contact with the ozone gas to obtain a mixed liquid containing ozone and a pressure type filter (3) for pressurizing and filtering the mixed liquid to obtain treated water, and the ejector and the pressure type filter are connected without interposing a reaction tank. The water treatment method using this apparatus is also disclosed.
