Abstract: A dialysis system is disclosed. An example dialysis system includes a water treatment device configured to provide purified water and a dialysis machine including a dialysate holding tank, and a dialysate mixing pump connected to a source of concentrate. The dialysis machine is configured to prepare dialysate using the purified water by receiving an indication that a batch of dialysate is needed, transmitting a first message to the water treatment device to begin providing the purified water, and causing the dialysate mixing pump to pump a concentrate from the source of concentrate for mixing with the purified water to form the dialysate for storage in the dialysate holding tank. After the batch of the dialysate has been stored to the dialysate holding tank, the dialysis machine transmits a second message to the water treatment device to stop providing the purified water.

Abstract: A water purification apparatus (1) comprising a Reverse Osmosis, RO, device (26). The RO device (26) comprises a RO membrane (26a) and a feed pump (23). The apparatus (1) also comprises a recirculation mechanism (33) arranged to recirculate a portion of the reject water to the feed water, a temperature sensor device arranged to measure a temperature indicative of the temperature of the RO membrane (26a), and a flow rate sensor device arranged to measure a flow rate indicative of the permeate flow rate of the permeate water. The apparatus (1) further comprises a control arrangement (50) configured to control recirculation to achieve a predetermined recovery ratio. The control arrangement (50) is also configured to control the rate of the feed pump (23), based on the measured temperature indicative of the temperature of the RO membrane (26a) and a desired permeate conductivity, to make the permeate flow rate equal to, or within a predetermined margin of, an energy efficient permeate flow rate determined based on a predetermined relation between RO membrane temperature, permeate flow rate and permeate conductivity. The disclosure also related to a corresponding method.

Abstract: The invention provides a system for characterizing an effluent sample from a patient undergoing peritoneal dialysis. The system features a container for enclosing the effluent sample, and optical system, an electrical system, and a processor. The optical system features a light source and a photodetector, the light source emitting a beam of radiation that passes through the container and irradiates the effluent sample, and the photodetector detecting the radiation after it irradiates the effluent sample to generate an optical signal. The electrical system typically features a first pair of electrodes and a second pair electrodes, both attached directly to the container and arranged to measure a capacitance of the effluent sample to generate a capacitance signal. The processor operates an algorithm that collectively processes the optical and capacitance signals to characterize the effluent sample.
