Abstract:
The device for producing ultrapure water according to the reverse osmosis principle, comprising a reverse osmosis filter which is subdivided by the RO membrane into a primary circuit and into a secondary circuit, and a pump for the primary circuit, and a flow resistance valve required downstream of the RO membrane for pressure build-up in the primary circuit is characterized in that at least one cleaning chamber with decalcifying ability and a discharge valve are located in the primary circuit and that the flow in the primary circuit is adjustable via a valve.
Abstract:
The coupling element is characterized by the locking pieces, on the coupling element and on the nipple element, with circumferentially extending projections which viewed in cross-section are substantially serrated (or roof-shaped) and which extend around a part of the whole circumference of the locking pieces. The coupling element and the nipple element are elastically deformed during the inserting operation and lock in place one after the other. At least one circumferential section of the locking pieces, of the coupling element and of the nipple element, is free of serrated (or roof-shaped) projections and has guides for the twist-proof inserting operation.
Abstract:
The water treatment system, particularly reverse-osmosis system, comprising a water line with a plurality of filter stages, is characterized in that before and after at least one filter stage a respective line branches off from the water line, which is provided with a valve adapted to be switched by a control device and leads to a pressure sensor device.
Abstract:
The water treatment system, particularly pre-filtration unit of the water treatment system, comprising at least one chlorine sensor device, includes a salt-water treatment device which is connected to the chlorine sensor device, an electrolysis cell being disposed in the associated line, and thereafter a pump and a release valve.
Abstract:
The coupling element is characterized in that that on the locking pieces, on the coupling element and on the nipple element there are formed circumferentially extending projections which viewed in cross-section are substantially roof-shaped or substantially serrated and which extend around a part of the whole circumference of the locking pieces, the coupling element and the nipple element and are elastically deformed during the inserting operation and lock in place one after the other, and that at least one circumferential section of the locking pieces, of the coupling element and of the nipple element are free of the roof-shaped or serrated projections and have guide means for the twist-proof inserting operation.
Abstract:
The fluid system for supplying a dialysis device with permeate has a secondary ring line which is guided within a common insulating hose or another form-fit sheathing. Thus, heat loss is reduced and use is facilitated. The insulating hose having the inner lines is adapted to a flow-optimized coupling handpiece having low dead space, which can preferably be coupled to a mating coupling piece.
Abstract:
A circulation pump and an electrochemical ozone generator are integrated into the permeate return line of an RO system, and the permeate return line is connected in flow direction behind the circulation pump and the ozone generator by a recirculation line to the permeate supply line, which can form a closed circuit where the ozonized permeate circulates until all organic contaminants have been killed or decomposed by the ozone in that part of the line system. Valves are integrated, respectively, into the recirculation line and the permeate return line downstream of the branch of the recirculation line. During normal operation of the RO system, the recirculation line valve is connected for feeding connected dialysis devices while the permeate return line valve is open, so excessive permeate that was not taken by the dialysis devices can flow into the supply tank. Alternatively, the permeate can be discharged into an outlet.
