摘要

A device for the filtration of liquids comprises a plurality of membrane curtains (2), each curtain being formed of a singular row of capillary membranes (5). The device further comprises at least one bottom header (3) provided at a lower end of the membrane curtains (lower end of the capillary membranes) and linked to the capillary membranes of at least one membrane curtain and an individual top header (4) for each membrane curtain. The top header is provided at an upper end of the membrane curtain and is linked to the capillary membranes thereof. Top headers of adjacent membrane curtains (41, 42) are arranged at different heights and the capillary membranes (5) of said adjacent membrane curtains (2) have different lengths.
