to allow the sudden movement of the membrane 19 to be carried out.

  
Instead of plunging the membrane 19 into the basin 4, it is also possible to run water taken from the piping 3 over all or part of the surface of this membrane 19 and collect the runoff water. in a channel 21. Such a solution is shown * in Figure 8.

Along the upper edge of the panel 23 is disposed a channel 26 supplied with water pumped by a rising pipe 27.
