Claim 0:
1. A system, comprising:
a dialysate flow path; the dialysate flow path fluidly connectable to a dialysate inlet of a dialyzer and a dialysate outlet of the dialyzer;
a sorbent cartridge in the dialysate flow path;
a degasser in the dialysate flow path downstream of the sorbent cartridge;
a bicarbonate source fluidly connected to the dialysate flow path;
a water source fluidly connected to the dialysate flow path;
a first conductivity sensor downstream of the sorbent cartridge; and
a control system; the control system programmed to determine a pH of a fluid exiting the sorbent cartridge; wherein:
while pH of the fluid exiting the sorbent cartridge is below a preset pH, the control system is programmed to control a sodium concentration in the fluid based on a sodium prescription and a conductivity measured by the first conductivity sensor; and to control a bicarbonate concentration in the fluid based on a bicarbonate prescription; and
while pH of the fluid exiting the sorbent cartridge is above a preset pH, the control system controls a sodium concentration in the fluid based on a sodium prescription and a conductivity measured by a second conductivity sensor upstream of the sorbent cartridge.
