摘要： The disclosure relates to waste water treatment. A flow of an aqueous solution comprising a chloride salt is electrolysed between an anode and a cathode of an electrolysis cell. The flow of aqueous solution is separated from the anode by a first ion-exchange structure and from the cathode by a second ion-exchange structure. A first auxiliary flow of liquid is driven through a first auxiliary region between the anode and the first ion-exchange structure during the electrolysis. A second auxiliary flow of liquid is driven through a second auxiliary region between the cathode and the second ion-exchange structure during the electrolysis. The first auxiliary flow, or liquid from the first auxiliary flow, is used to treat waste water.
