Abstract: The device for obtaining desalinated permeate solution from raw water, has a separating chamber (2), a filter membrane (3) dividing the separating chamber into a concentrate chamber (4) and a permeate chamber (5), and an inlet line (6) that is connected to the concentrate chamber and supplies 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. The device for obtaining desalinated permeate solution from raw water, has a separating chamber (2), a filter membrane (3) dividing the separating chamber into a concentrate chamber (4) and a permeate chamber (5), and an inlet line (6) that is connected to the concentrate chamber and supplies 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. 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, and the concentrate line opens into the jet head. An outlet concentrate line is connected to the jet nozzle whose accelerated exit jet enters into the outlet concentrate line. The jet nozzle has a low-pressure chamber surrounding the exit jet. A suction line branches off the low-pressure chamber of the jet nozzle and is connected to the pressurized chamber. A raw water pipe line is connected to the inlet line, the concentrate line, suction line, the concentrate chamber and the pressure chamber. A switching valve is arranged in the raw water line. A flow switch effectively operates in the direction of the membrane and is arranged in the direction of the permeate line. The flow switch detects the water flow in direction over a sensor/paddle. The flow switch is arranged in the bypass line and switches the switching valve in the raw water pipe line. A throttle element is arranged between the bypass-inlet and -outlet in the pipe and is formed as cross-section constriction. A throttle valve is switched to the flow switch in the bypass line. The switching valve is controlled by effective connection between the switching contact and the magnet. A push-button switch is arranged in the permeate chamber to control the switching valve. A flow rate sensor is arranged in effective connection with the switching valve in the transition area of the permeate chamber for permeate line. The supply lines are subjected over the flow switch to control pressure- or cross-section of the membrane. The flow switch is a single-sided operating pressure sensor.
