ABSTRACT:
A membrane separation device is disclosed having a cylindrical membrane support (4), which is sealed off between a top plate (26) and a bottom plate (28), whereon the cylindrical outer surface of the membranes support a membrane (6) is located, and which is surrounded by cylindrical components (14, 8) which are sealed off in the top plate and bottom plate thereby forming a cylindrical ring area (16). Permeate collection bores (20) communicate with the membrane through the membrane support and are connected with a permeate draw off connection (60). The suction side of a circulation pump (44) is connected with an enclosed inner chamber (47) formed by the cylindrical membrane support. The outer ring area is connected to the pressure side of the circulation pump and communicates with the inner chamber through a circulation channel (54). The inner chamber is connected to a infeed connection (58). The circulation pump communicates with a draw off (64) on the pressure side for the extraction of concentrate.
