Device for the separation of a fluid into at least two fractions, using a plurality of membrane filters, and use thereof

The invention relates to a separated the liquid with multiple filter membrane by at least two parts of apparatus and device. Device for the invention comprises at least film support plate (8) sub-group (2a, 2b, 2c), the filtering membrane (10) is fixed support plate each on the opposite. According to the invention, the filter membrane is fixed on the film support plate (8) one part, a bracket plate comprises a circular device, wherein the device is used to introduce the liquid first part, comprising enables (10) to flow through the film for releasing to the first body channel; moreover the device on support plate (8). In addition, the first part of the liquid (10) and on the recycling with the recycling space between the film support plate (8) of the film. The sub-module (2a, 2b, 2c) film support plates (8) each other are assembled on. The two adjacent plate (8) of the fixing film (10) in the opposite defines the liquid free air cavity (13). For going through the membrane (10) portion of the first body which comprises: For component (2a, 2b, 2c) through the film the part of the support, the part for first body recycling cavity, is placed on rigid transparent part (16) of the part. Hard transparent part of the shift connected with the film support plate (8) longitudinal direction; the supporting plate and sealing element (17) is. Moreover, a sealing part of said of the driving to prevent the liquid is connected to the corresponding recycling space.
