1. A dialysis system, comprising:
- a dialysis machine; and
a module that is directly, fluidly coupled to the dialysis machine via a fluid inlet line and a fluid outlet line such that dialysis solution flows directly from the module to the dialysis machine, through the dialysis machine, and directly from the dialysis machine back to the module, the module being electrically coupled to the dialysis machine and fluidly coupled to a dialysis solution reservoir, the module retaining a device in a manner such that dialysis solution can pass through the device, the device being adapted to remove one or more substances from the dialysis solution as the dialysis solution passes through the device, the module comprisinga fluid line connected to the device, the fluid line being arranged so that dialysis solution exiting the device passes through the fluid line, anda sodium control system in fluid communication with the fluid line, the sodium control system being adapted to alter a sodium concentration of dialysis solution passing through the fluid line,wherein the dialysis system controls a flow rate of dialysis solution from the module to the dialysis machine in a manner such that dialysis solution is diverted to the dialysis solution reservoir if an actual flow rate of dialysis solution from the module to the dialysis machine is greater than a desired flow rate and dialysis solution is drawn from the dialysis solution reservoir if the actual flow rate of dialysis solution from the module to the dialysis machine is less than the desired flow rate.

Abstract
This disclosure generally relates to dialysis systems and related methods. In one aspect of the invention, a dialysis system includes a device configured so that a medical fluid can pass therethrough, and the device is adapted to remove one or more substances from the medical fluid as the medical fluid passes through the device. The dialysis system can also include a sodium control system adapted to alter a sodium concentration of the medical fluid.
