PROBLEM TO BE SOLVED: To provide a method of efficiently warming raw water to be used for preparing dialysate by heat exchange by utilizing a temperature difference between the raw water and used dialysate when discharging the used dialysate in a multiple-patient dialyzer.SOLUTION: The used dialysate discharged from each console is collected to one pipe provided with a heat exchanger; the raw water is warmed by the heat exchange by utilizing the temperature difference between the used dialysate and the raw water, and then the used dialysate used in the heat exchange is discharged. Further, RO waste water is supplied to the heat exchanger, the raw water is warmed by the heat exchange utilizing the temperature difference between the RO waste water and the raw water, and then the RO waste water used in the heat exchange is discharged. |
