An arrangement for permitting a first liquid to flow close to a second liquid, but without being intermixed therewith, comprises a first plurality of plates (11) and a second plurality of plates (12), which are located between plates in the first plurality of plates but spaced therefrom by means of separating pieces (13). Each separating piece (13) comprises a frame (130) about plate-shaped plane-parallel partial pieces, viz. an outer porous and hydrophobic plastic diaphragm (21), an intermediate distance network (22) of plastic and an outer thin plastic foil (23). The frame (130) includes infeed holes (1301) for air and outfeed holes (1302) for water. The voids of the plastic diaphragm (21) have a radius within the range 2 to 5//cm. The distance network (22) has a thickness of 1 to 2 mm and consists of intersecting strips. The plastic foil (23) has a thickness of about0, 1 mm. The plates (11, 12) comprise a frame (110, 120) with four through holes, of which two holes (for example 111, 114) have connection to a depression (115) in the plate, while two holes (112, 113) have no such connection. The plates in the two pluralities of plates are so turned that holes (122, 123) with connection in the first plurality of plates correspond to holes (112, 113) without connection in the remaining plurality of plates. The frames (130) of the separating pieces include four through holes (131, 132, 133, 134) corresponding to the holes of the plates. Inflow means (101, 103) and, respectively, outflow means (104, 102) are connected to respective holes (111, 123; 114, 122) with connection in the two pluralities of plates. |
