12. A reverse osmosis device (RO-device) configured to produce ultra-pure water for a dialysis machine, the RO-device comprising:
a sensor unit configured to collect sensor data based on the produced water, the sensor data comprising measurements of feed water conductivity, permeate conductivity, retention, and water temperature; and
an electronic data interface communicably coupled to an evaluation unit remote from the RO-device via a network and configured to transmit the sensor data collected by the sensor unit to the evaluation unit via the network;
a control unit communicably coupled to the evaluation unit via the network and configured to receive result data from the evaluation unit via the network, wherein the control unit is configured to automatically control a flow of ultrapure water from the RO-device to the dialysis machine based on a preliminary result by the evaluation unit, wherein the evaluation unit is configured to provide the preliminary result according to a PUSH protocol, the evaluation unit having access to a rule base comprising rules that define actions to be taken based on the collected sensor data, on water consumption data, and on validated result data generated and transmitted based on an analysis, by an analysis unit of a laboratory system, of a contamination level of periodically sampled water samples produced from the RO-device.
