Abstract: A water treatment system is provided, including a raw water tank connected to a water supply, a reverse osmosis unit arranged to produce purified water from water input from the raw water tank via a raw water supply line, at least one water treatment facility alongside the raw water supply line downstream of the raw water tank and upstream of the reverse osmosis unit, and a reuse water feedback line arranged to feed waste water and/or grey water collected from the reverse osmosis unit and/or the at least one water treatment facility back to the raw water tank for reuse. In a water treatment method in such a water treatment system, waste water and/or grey water collected from the reverse osmosis unit and/or the at least one water treatment facility is fed back to the raw water tank for reuse.

Abstract: The invention concerns a device for extra-corporal blood treatment, including an extra-corporal blood circulation for the pumping of blood, where individual components of the extra-corporal blood circulation are inside and outside of a casing of the device, and a base socket is attached below the casing, which includes a collection trough in which liquids leaking inside the casing can be collected. The device has a sensor with which the presence of liquid within the collection trough is measurable. The device includes receptacle resources for the reception of leaking liquids occurring outside of the casing, where the receptacle resources are developed so that, above a specified quantity, they route leaking liquids into the collection trough.

Abstract: Blood treatment/dialysis systems are disclosed. The systems include a water treatment unit, preferably of the reverse osmosis type, whose outlet has connected thereto a water supply line provided with a number of branch connections having fluidly coupled thereto blood treatment/dialysis machines in a selective manner, and a drain line through which exhausted blood treatment fluid can be discharged from fluidly coupled blood treatment/dialysis machines. Also disclosed is a machine-external heat exchanger, which is connected to the water supply line upstream of the branch connections on one side and to the drain line on the other side.

Abstract: A pressure compensation valve for a dialysis machine is disclosed. The pressure compensation valve has a valve housing, in which a flow path with fresh dialysate is separated from a flow path with exhausted dialysate by a diaphragm. The diaphragm and the valve housing are configured such that pressure compensation is possible. In addition, the diaphragm is configured such that no vibrations or a reduced amount of vibrations and/or no noise emission or a reduced amount of noise emission will occur during operation. Furthermore, a dialysis machine comprising such a pressure compensation valve is disclosed. The dialysis machine comprises a balancing unit, and the pressure compensation valve is arranged on the outlet side of the balancing unit.
