Abstract: Waste water is purified by passing through a vessel in which small particles of insoluble cathodes interact with anodes to form galvanic couples. During this process, chemical reduction of ions of heavy metals in the water occurs by ions and hydroxides formed during electrochemical dissolution of anodes. The hydroxides are an excellent coagulating agent which absorbs impurities contained in the water. Pressurized air can saturate the waste water simultaneously with passing through the vessel with anodes in order to produce process floatation using hydroxides as coagulant. The temperature of the waste water can be increased in order to intensity the process of treatment.
