Abstract
A technology of electrochemical oxidation of bromide and chloride ions present in the brines of calcium chloride type involving an electrolyzer without a diaphragm is proposed. This technology allows one to obtain active chlorine from the initial raw material and to exclude transportation of liquid chlorine to consumption sites. It is proposed to use an excess of chlorine formed during electrolysis to oxidize bromide ions in the fresh portions of brine.
