Apparatus for producing purified hydrogen water for dialysis and method for producing purified hydrogen water for dialysis

Abstract

This invention provides a dialysis-grade purified hydrogen water production apparatus and a method for producing purified hydrogen water for dialysis, which can be used in actual dialysis in a dialysis machine to produce dialysis fluid having a dissolved hydrogen concentration of approximately 0.3 mg / L at a water temperature equivalent to the human body temperature. [Solution] The dialysis-use purified hydrogen water production apparatus comprises a hydrogen water raw water production means that generates hydrogen water raw water by dissolving hydrogen gas in raw water, and a purified hydrogen water production means that has a reverse osmosis membrane, and the hydrogen water raw water supplied from the hydrogen water raw water production means is pressurized by a pressurizing means and supplied to the primary side of the reverse osmosis membrane, and purified hydrogen water is produced by permeating it to the secondary side of the reverse osmosis membrane. The hydrogen water raw water production means is configured to control the gas pressure of the hydrogen gas dissolved in the hydrogen water raw water so that the dissolved hydrogen concentration of the purified hydrogen water obtained by permeating it to the secondary side of the reverse osmosis membrane is 0.217 times or more the dissolved oxygen concentration in the purified hydrogen water.
