description PURPOSE:To make it possible to easily and surely monitor inferior water removal by connecting a bypass pipe between three-way selector valves disposed respectively in a dialysate supply system and a dialysate discharge system, by providing a dialysate pressure sensor in a uniform flow rate circuit, and by providing back pressure detecting sensors respectively on the discharge sides of a dual pump and a water removing pump. CONSTITUTION:Back pressure detecting sensors 46, 48 are provided respectively to a liquid supply side back pressure valve 34 and a liquid discharge side back pressure valve 36 which are arranged on the discharge sides of a dual pump 12 disposed in a dialysate supply system 14 and a dialysate discharge system 16. A back pressure detecting sensor 50 is provided to a back pressure valve 38 arranged on the discharge side of a water removing pump 30 disposed in a water removing system 32. Further, a dialysate pressure sensor 52 for measuring the pressure of dialysate is arranged upstream of a circulating pump 26 disposed in the dialysate discharge system 16. Further, three-way selector valves 20, 22 are changed over so as to communicate the dialysate supply system 14 and the dialysate discharge system with a dialyzer 10, and then the pumps are operated. The dialysate supply system 14 and the dialysate discharge system 16 constitute a uniform flow rate circuit.
