MEMBRANE DISTILLATION PROCESS AND MEMBRANE DISTILLATION DEVICE

摘要

In a membrane distillation process in which a liquid to be concentrated is separated from a vapor space (11) by a vapor-permeable liquid- or water-tight membrane or membrane wall (13), to set the absolute pressure of the liquid to be concentrated a reduced pressure is imparted to this which lowers the absolute pressure of the liquid to be concentrated. A corresponding membrane distillation device is also specified.
