Methods and related apparatuses for sorbent recharging are provided. The methods and related apparatuses for recharging can recharge a specific rechargeable layer or module of a sorbent material such as zirconium phosphate in a sorbent cartridge. The methods and apparatuses include a fluid source containing at least one recharging fluid, wherein the fluid source is fluidly connectable to at least one rechargeable sorbent module for use in sorbent dialysis in a fluid flow path. The methods and apparatuses include passing a single solution through the zirconium phosphate for ion exchanges, resulting in zirconium phosphate to maintain a substantially consistent pH in a dialysate used during dialysis.
