1. A system for kidney replacement therapy and sodium management, comprising:

  • a dialysate flow loop for circulating a dialysate through a dialyzer where at least one waste species enters the dialysate;

    a dialysate regeneration unit for removing at least a portion of the at least one waste species and releasing at least one conductive species to the dialysate or absorbing at least one conductive species from the dialysate;

    a conductivity detector that measures the conductivity or sodium ion concentration of the dialysate;

    a sodium management system for generating a sodium-modified fluid for controlled addition to the dialysate in the dialysate flow loop, the sodium-modified fluid generated by the sodium management system from any one of an input dialysate, input ultrafiltrate, input solid sodium salt or input concentrated sodium resulting in a sodium ion concentration or conductivity that is higher or lower than the fluid in the dialysate flow loop.
