Abstract:
1. A device for producing ultrapure water according to the reverse osmosis principle, comprising a reverse osmosis filter which is subdivided by a reverse osmosis membrane (RO membrane) into a primary circuit and into a secondary circuit, a pump upstream of the RO membrane and downstream of a buffer vessel having multiple inlets and an outlet wherein fluid exiting the buffer vessel can enter the pump before entering the RO membrane, a flow resistance valve in the primary circuit downstream of the RO membrane for pressure build-up in the RO membrane wherein fluid exiting the RO membrane can enter the flow resistance valve before entering the buffer vessel, at least one cleaning chamber with decalcification means downstream of the flow resistance valve and a centrifugal chamber downstream of the least one cleaning chamber and upstream of the buffer vessel wherein fluid exiting the flow resistance valve can enter the cleaning chamber and the centrifugal chamber before entering the buffer vessel, the centrifugal chamber having a bottom connected to a discharge valve, wherein the flow resistance valve can be opened by a motor to flush the surfaces of the liquid-conducting components.
