A Study on the Electrochemical Ammonium Removal of Tannery Wastewater Using a Packed Activated Carbon Cell |
| Abstract |
In order to remove ammonium for tannery wastewater, electrochemical-oxidation using packed activated carbon was investigated. As electrode, platinium platinized anode and stainlessteel 316L cathode were used. Ammonium elimination was influenced by concentration of chloride, electrical dencity and negatively influenced by the presence of organic compounds. Ammonium elimination efficiency after 15min of electrolysis at a current dencity of 7.9A/dm² and chloride concentration of 11,000㎎/L was equal to about 99.5%. The removal efficiency of chemically and biologically treated wastewater was about twice as good as anly chemically pretreated wastewater. Electrooxidation using paked activated carbon proved more efficient about 50% than the conventional electrical oxidation system. In conculusion electrochemical oxidation system can be used as a polishing step for the biological step for the treatment of tannery wastewater. |
