In order to avoid the risk of scale formation, [polarity reversal electrodialysis] consists in reversing the polarity of the electrodes on a regular basis(for instance for five minutes every 30-60 minutes), thus instantaneously switching the concentration and desalination compartments, and thereby the position of the polarization layers that change sides on the membrane.  1, fiche 1, Anglais, - polarity%20reversal%20electrodialysis

[L']électrodialyse à inversion de polarité [...] consiste, pour éviter les risques d'entartrage, à inverser régulièrement la polarité des électrodes (par exemple 5 minutes toutes les 30 à 60 minutes) et à permuter ainsi instantanément compartiments de concentration et compartiments de dessalement et donc la position des couches de polarisation qui changent de côté de la membrane.  1, fiche 1, Français, - %C3%A9lectrodialyse%20%C3%A0%20inversion%20de%20polarit%C3%A9

The SEMP ship Yamato 1 is packed with the huge power and refrigeration systems needed to run it. A ten-man crew squeezes into a small cockpit at the front. Despite these limitations, the Japanese are hoping that SEMP systems will become smaller and more powerful leading to a new generation of fast passenger ferries and cargo ships. Unlike today's ships they will be highly manoeuvrable : by reversing the polarity of both thrusters, a SEMP ship should be able to come rapidly to a halt. Reversing just one drive would make it turn on a yen. It would also be eerily quiet. This has prompted the America's IEEE to try to fit SEMP drives into a submarine-echoes, as it were, of the "caterpillar drive" used by the silent submarine in the film "The Hunt for Red October".  1, fiche 4, Anglais, - SEMP%20ship
