PURPOSE:To obtain sterilized and odorless water from which impurities are removed at any time and at any place without application of any chemicals by providing two filtration devices, two ceramic deodorization tanks, an ultraviolet sterilization device and a treated water curing tank. CONSTITUTION:Untreated water containing impurities is mixed with a filtration assistant (f), and the mixture is sent to a first filter body A1. Then it is filtered with a cylindrical filtration cloth 5 with a bottom, then it is deodorized by deodorization ceramics 8 in a first ceramic deodorization tank C. Further, the deodorized water is supplied to an ultraviolet sterilization device D for sterilization. After this, the sterilized water is permitted to pass through the ceramic deodorization tank 8 of a second ceramic deodorization tank E top be stored in a treated water aging tank F. Next, a filtration assistant (f) is mixed with this stored water and sent to a second filter body A2, where it is filtered with a cylindrical cloth with a bottom 5b for filtration. This purified water is supplied, and furthermore, the filtration assistant (f) sticking to the cylindrical filtration clothes 5, 5b is dropped off by vibration of a coil spring S with an air blown in from air injection pipes 7a, 7c.
