| Abstract |
| This research tried to observe according to the change of the hydraulic retention time whether the Modified DEPHANOX process of applying the rotating biological contactor to the industrial wastewater through the process operating of the pilot scale maintained the nitrogen and organic compound the stable process efficiency considering in the industrial wastewater. In operating the Modified DEPHANOX process with the rotating biological contactor as the pilot-scale at the hydraulic retention time of 12 hrs, the nitrogen removal efficiency was 75%, the organic compound removal efficiency was 83%, and the phosphorous removal efficiency was 73% respectively. Despite the advantages of using Modified DEPHANOX with rotating biological contactor, this process was found to be ineffective when the sample industrial wastewater had a high concentration of toxic substance and oil. Therefore, in order to obtain stable nitrogen removal efficiency in these settings, further future studies may be necessary. |
