DEF

Procédé qui consiste à remplacer le D20 contenu dans les résines échangeuses d'ions par de l'H20 (avant l'évacuation des résines). Le H20 refoule l'eau lourde en remontant lentement à travers le lit de résines de façon à ce que tout le D20 soit déplacé et que les ions D plus et OD moins des noyaux de la résine soient remplacés par des ions H plus et OH moins.
