- 摘要：
PROBLEM TO BE SOLVED: To provide a method and apparatus excellent economically and environmentally for producing refined water capable of efficiently sterilizing the apparatus with hot water and thereby reducing a sterilizing time as well as heat energy used for producing hot water.
SOLUTION: The apparatus comprises as main components a raw water supplying tank 1 installed at its upstream side and toward its downstream side in turn an activated carbon treatment unit 3, a nano-permeable membrane treatment unit 4, a reverse osmosis membrane treatment unit 5, and a refined water storage tank 6 provided with a heating means 7 for storing the refined water. The apparatus further comprises a by-pass main pipe 9 for delivering the refined water heated by the heating means 7 to the above treatment units respectively and by-pass branch pipes 9a, 9b, 9c branching off from the by-pass main pipe 9 for delivering the heated refined water to the upstream side of each above treatment unit. The above treatment units are sterilized and disinfected in turn from the upstream side unit to the downstream side units, keeping a prescribed temperature for a prescribed time respectively.
