Beschreibung
Zusammenfassung:	The invention relates to systems for membrane purification and/or demineralization with recirculation of liquid, primarily water. The system comprises an untreated liquid line with a pump mounted thereon, a membrane element connected to a purified liquid line and to a liquid recirculation line having a pressure regulator mounted thereon and furthermore being connected to a liquid drainage line, and a controller, and is capable of spontaneously maintaining a pressure of not less than is necessary for carrying out a filtration process as a result of the pressure regulator being in the form of a mechanical spring-loaded valve. Furthermore, untreated liquid is always supplied at a greater ratio rate than the overall rate of removing purified liquid and drainage.
