To provide a pure water production apparatus capable of stably producing pure water having high water quality.SOLUTION: A part of fresh water in a fresh water tank 1 is used as supply water of a low pressure boiler or a middle pressure boiler. The fresh water in the fresh water tank 1 is supplied through a pipe 2, a bulb 3, a water supply pump 4 and an MF membrane device 5 constituting a main system 10 to an RO device 6. Permeable water of the RO device 6 is supplied to an electric deionization device 11. A preliminary system 20 passes the fresh water from the fresh water tank 1 to an MF membrane device 25 with a pipe 21, a bulb 22 and a water supply pump 24, and passes the MF filtrate water to the ion exchange resin device 26 and deionizes the MF filtrate water to produce pure water.SELECTED DRAWING: Figure 1 【課題】安定して高い水質の純水を製造することができる純水製造装置を提供する。【解決手段】淡水タンク１内の淡水の一部は、低圧ボイラ又は中圧ボイラの給水として用いられる。淡水タンク１内の淡水は、主系列１０を構成する配管２、バルブ３、給水ポンプ４及びＭＦ膜装置５を介してＲＯ装置６へ供給される。ＲＯ装置６の透過水は、電気脱イオン装置１１に供給される。予備系列２０は、淡水タンク１からの淡水を配管２１、バルブ２２及び給水ポンプ２４によってＭＦ膜装置２５に通水し、ＭＦ濾過水をイオン交換樹脂装置２６に通水して脱イオン処理して純水を製造するよう構成されている。【選択図】図１
