Abstract

PROBLEM TO BE SOLVED: To prevent the propagation of various bacteria in mineral water stored in a water tank. SOLUTION: A residual chlorine removing agent cartridge 10 and a hollow fiber membrane module 11 are provided to the water supply passage 14 reaching a water supply port 13 from the emitting port 6 provided to the bottom part of a water tank 1 and a mineral component eluting cartridge 3 is provided in the water tank 1. Mineral water containing mineral components properly is obtained by passing the tap water in the water tank 1 through the mineral component eluting cartridge 3. In this stage, chlorine remains in mineral water and mineral water can be stored while the propagation of miscellaneous germs in the mineral water in the water tank 1 is prevented. Since the mineral water passes through the residual chlorine removing agent cartridge 10 when the mineral water in the water tank 1 is supplied, residual chlorine in mineral water is removed.
