1. A water management system for use in sorbent dialysis comprising:
- a rinse water reservoir configured to receive purified water obtained from a sorbent cartridge containing one or more sorbent materials, wherein the rinse water reservoir is fluidly connectable to a rinse water reservoir line, the rinse water reservoir line fluidly connectable to a dialysate circuit by one or more valves;
wherein the rinse water reservoir line is fluidly connectable to the dialysate circuit at a position upstream of the sorbent cartridge;
a water source, wherein the one or more valves are fluidly connectable to the water source and the sorbent cartridge,wherein water from the water source is directed to the sorbent cartridge and the water is purified by the sorbent cartridge, and is stored in the rinse water reservoir; and
a drain, wherein the drain is fluidly connectable to at least one drain valve;
wherein the at least one drain valve is fluidly connectable to the dialysate circuit.

Abstract
A water management system for use in dialysis. The water management system includes apparatuses to generate purified water, and a reservoir for storing the purified water. The reservoir can be connected to a dialysate flow loop and the purified water can be generated, stored, and used for later cleaning and disinfection of the dialysis flow loop and the components thereon.

21. A method of disinfecting a dialysis system comprising the steps of:
-
directing purified water from a rinse water reservoir through lines of the dialysis system, wherein the purified water is produced by having water pass through a sorbent cartridge prior to the purified water being placed in the rinse water reservoir; and circulating heated purified water through the dialysis system; wherein the rinse water reservoir is configured to receive purified water obtained from the sorbent cartridge containing one or more sorbent materials, wherein the rinse water reservoir is fluidly connectable to a rinse water reservoir line, the rinse water reservoir line fluidly connectable to a dialysate circuit by one or more valves;
wherein the rinse water reservoir line is fluidly connectable to the dialysate circuit at a position upstream of the sorbent cartridge;wherein the dialysis system comprises a water source, wherein the one or more valves are fluidly connectable to the water source and the sorbent cartridge, wherein water from the water source is directed to the sorbent cartridge and the water is purified by the sorbent cartridge, and is stored in the rinse water reservoir; and wherein the dialysis system comprises a drain, wherein the drain is fluidly connectable to at least one drain valve;
wherein the at least one drain valve is fluidly connectable to the dialysate circuit. - View Dependent Claims (22, 23, 24, 25, 26)
