    The packs also contain barrier plates.23 installed at different levels in two collector channels and blocking these channels, forcing the liquid to flow from one channel to the other.
    The support plates may include passages 24 leading from the top and bottom surfaces of each plate to a central channel formed by the central holes. This channel is connected to a central outlet 25 in the upper flange 11, which also has an opening 26 for introducing the initial mixture. The outlet 27 is located in the bottom flange 12.
    In the edges of each base plate 9, holes 28 can be made for the outlet of the permeate 3, which are connected to an annular internal channel 29 having an outlet on the upper and lower surfaces of each base plate. The connecting channel 30 connects the collector channel to the inlet 31 in the lower flange 12. The inlet 31 is connected to the central channel, and the latter is connected to the central outlet 32 in the upper (flange 11.
    The apparatus shown in Fig. 5 operates as follows.
    The original liquid is introduced through the opening 26 and enters the collection channel. Due to the presence of the barrier plates 23. in this channel, the liquid flows into the second collector channel through parallel intermembrane channels. The next barrier plate 23 again forces the liquid to flow into the first collection channel, etc. The concentrated solution is discharged from the apparatus through hole $ 27 in the bottom flange 12.
    Permeate passing through membranes 10 flows through channels 24 into the central channel and is removed from there through opening 25.10
    In the apparatus shown in Fig. 6, the concentrate passes through the opening 27 along the connecting channel 30 into the central channel, moves upward and out of the apparatus through the opening 32. Permeate is collected in the annular channels 29 and is discharged through the openings 28.
    It is advisable to place the bags horizontally rather than vertically, thus making it easier to replace failed membranes and backing plates.
