  • Method of and device for industrial waste water treatment
    Patent number: 5658450
    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.

  • Method of and device for industrial waste water treatment
    Patent number: 5385653
    Abstract: Waste water is purified by passing through a vessel in which small coal particles interact with metal to form galvanic couples which produce ions of Fe. These ions are involved in chemical reduction of ions of heavy metals and formation of a coagulating agent, which removes impurities from waste water. Pressurized air can saturate the waste water simultaneously with passing through the vessel with metal in order to produce process floatation using Fe(OH).sub.2 as a coagulant.
