METHOD FOR PREVENTING FOULING IN A REVERSE ELECTRODIALYSES STACK

摘要

The invention relates to a method and a device for preventing fouling in a reverse electrodialysis process. The method comprises the steps of : providing a reversed electrodialysis stack, comprising a number of membranes; supplying the stack with at least two feed streams; and - applying a preventive periodic osmotic shock to the fouling layers of the membranes.
