A device for producing a permeate from a concentrate has a separating chamber and a filter membrane dividing the separating chamber into a concentrate chamber and a permeate chamber. An inlet line is connected to the concentrate chamber and introduces the concentrate into the concentrate chamber. A concentrate line is branched off the concentrate chamber and has a control valve. A permeate line is branched off the permeate chamber. An accumulator is connected to the permeate line. A non-permeable separating membrane divides the accumulator into a storage chamber and a pressurized chamber, wherein the storage chamber is connected to the permeate line and the pressurized chamber is connected to the control valve of the concentrate line. The control valve is a jet nozzle and has a jet head, wherein the concentrate line opens into the jet head. An outlet concentrate line is connected to the jet nozzle opposite the concentrate line at a spacing to the jet head, wherein the jet head of the nozzle issues an accelerated exit jet entering the outlet concentrate line. The jet nozzle has an under pressure chamber surrounding the exit jet. A suction line branches off the under pressure chamber of the jet nozzle and is connected to the pressurized chamber.
