| Abstract: | The process of the electrocoagulation purification of water containing chromium, depending on pH, Cr6+ concentration, ions of metal impurities and ratios Fe2+ : Cr6+ have been investigated. We have found the upper boundary of chromium concentrations (150 mg/dm3) whereby its residual content in water does not exceed MAC for the discharge to the complex of facilities of water disposal. It has been shown that ions of metal impurities present in the water in electrocoagulation are removed together with chromium ions. |
