The concentrate return line of a device for producing ultrapure water according to the reverse osmosis principle has inserted thereinto a venturi tube with the convergence chamber and the divergence chamber, with a suction hose being mounted on the suction opening of the venturi pump and being connectable by means of a coupling either upstream of the venturi pump and of a flow resistance means to the concentrate return line or to an external container which contains a disinfectant or a cleaning agent. A disinfecting process can thereby be substantially automated. |
