1. A system, comprising:
a sorbent module containing at least zirconium oxide and/or zirconium phosphate;
a microbe removal layer upstream of the sorbent module; and
a control system programmed to:
calculate a remaining capacity of the sorbent module following a first dialysis session, wherein the remaining capacity of the sorbent module following the first dialysis session is a function of at least a weight of a patient;
calculate an estimated capacity of the sorbent module that would be required for a second dialysis session, wherein the second dialysis session would follow the first dialysis session; and
determine if the sorbent module can be reused for the second dialysis session, without recharging the sorbent module, based on the remaining capacity of the sorbent module and the capacity of the sorbent module required for the second dialysis session,
wherein the capacity of the sorbent module required for the second dialysis session is based on at least an expected dialysate flow rate through the sorbent module for the second dialysis session and expected duration of the second dialysis session.
