Abstract: A water preparation apparatus for determining an amount of total chlorine in purified water is disclosed. The water preparation apparatus includes a chlorine sensing system, a water pretreatment filter, a reverse osmosis filter, and an electrodeionization (“EDI”) module. The chlorine sensing system is configured to determine an amount of total chlorine in the purified water by applying, at a first time, a source voltage to the purified water and removing, at a second time, the source voltage. The chlorine sensing system then measures, after the second time, an electrical parameter of the purified water. The chlorine sensing system determines the amount of total chlorine in the purified water based on the measured electrical parameter.

Abstract: A system for reconstituting and sterilizing a concentrate includes a mixing container, a filtration device, and a product bag. The a mixing container has an inlet port and outlet port in fluid communication with a mixing chamber disposed between the inlet port and the outlet port. The mixing chamber is adapted to contain a product concentrate. The filtration device has an inlet and an outlet, the inlet of the filtration device coupled to the outlet port of the mixing container. The filtration device includes a filter membrane with a nominal pore size in a range of approximately 0.1 μm to approximately 0.5 μm. The product bag has an inlet port coupled to the outlet of the filtration device, and has a bladder defining an empty sterile chamber for receiving sterilized and reconstituted product resulting from mixing a diluent with a product concentrate in the mixing chamber to obtain a mixture then introduced through the filtration device to obtain the reconstituted and sterilized product.

Abstract: Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H+ZP within a casing for a treatment; and after the treatment, refurbishing the H+ZP while maintained within the casing via (i) regenerating the non-disinfected H+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H+ZP while maintained within the casing. Multiple batch sorbent refubishing implementations are also disclosed.

Abstract: The present disclosure provides devices and methods of using same for cleansing a solution (e.g., a salt or used dialysis solution) of urea via electrooxidation, and more specifically to cleansing a renal therapy solution/dialysis solution of urea via electrooxidation so that the renal therapy solution/dialysis solution can be used or reused for treatment of a patient. In an embodiment, a device for the removal of urea from a fluid having urea to produce a cleansed fluid includes a urea decomposition unit and an electrodialysis unit.

Abstract: A dialysis method and system for determining an amount of total chlorine in a partially purified water sample is disclosed. The system includes a water machine that produces at least partially purified water including an at least partially purified water sample and a dialysis machine that provides a dialysis treatment to a patient. The dialysis machine receives the at least partially purified water from the water machine to prepare dialysis fluid for the dialysis treatment. The system also includes a total chlorine detector configured to receive the at least partially purified water sample, at a first time apply a source voltage to the at least partially purified water sample, and at a second time stop applying the source voltage to the at least partially purified water sample and instead monitor a sensed electrical parameter to determine an amount of total chlorine in the at least partially purified water sample.
