1. A method of recharging a sorbent for dialysis, comprising the steps of:

  • connecting at least one reusable module containing either zirconium oxide or zirconium phosphate, and a second module in series with one or more connectors, wherein the reusable module and second module each contain one or more sorbent materials;

    fluidly connecting at least one connector to at least one wash line, wherein the wash line is fluidly connected to a recharger;

    fluidly connecting at least one connector to at least one bypass line, wherein the bypass line diverts flow from the connector to bypass at least one module;

    connecting a valve assembly to the connectors at junctions between the modules, wash lines and/or bypass lines;

    the valve assembly including a first valve positioned on a connector;

    connecting the first valve to a wash line and a bypass line;

    flowing spent dialysate through the reusable module and the second module; and

    selectively opening and closing the valve assembly to direct flow from the recharger, through the wash line, and through at least the reusable module to recharge the zirconium oxide or zirconium phosphate.
