  • Process for regulating an electro-dialyzer and improved electrodialysis apparatus
    Patent number: 4713156
    Abstract: A process and apparatus for regulating an electrodialyzer having a stack of ion-exchange membranes (2, 3) immersed in an electric field, and including sampling the dilute solution at the discharge (6), measuring in a cell (12) the content of a predetermined ion substance of this sample, in particular the content of free cyanide, and driving by means of a processing unit (14) a pump (15) as a function of that content so as to add a solution containing the ion substances (free cyanides) in an amount inversely related to the measured content at the intake (5) of the electrodialyzer, thereby eliminating electrodialyzer shutdown and membrane clogging.
