Process for electrolytic treatment of continuous running material in which the material runs through an electrolytic liquid and electric potential is applied to the material. In order to guarantee freedom from differential potential in the material to be treated in any form of electrolytic treatment, the differential potential in the treated material is measured after electrolytic treatment and at least the same degree of inverse compensating potential is applied to the material. In an apparatus to implement the process, comprising at least one treatment tank to hold the electrolytic liquid and through which the material being treated is guided by means of guide rolls, as well as comprising at least one pair of electrodes to apply electric potential in the material, at least one device is included to achieve this aim and which is used to measure the differential potential of the treated material, together with at least one pair of additional electrodes connected to an adjustable rectifier, where the device for measuring the differential potential is connected to the controlling part of the rectifier.
