Sorbent cartridge systems useful in regenerating or purifying dialysis solutions are described as well as methods to regenerate or purify spent dialysis solutions. Dialysis systems using the sorbent cartridge system of the present invention are further described.

A detachable module for optionally recharging sorbent materials, including zirconium phosphate, with an optional bypass and conduits for a sorbent cartridge. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged.

Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.

A sorbent based monitoring system for measuring the solute concentration of at least one component of a fluid. The system has a sorbent regeneration system for regeneration of the fluid and has a sorbent cartridge that has at least one material layer. The fluid is conveyed through the sorbent cartridge and contacts at least one sensor after having contacted at least one material layer.
