Abstract

Palm oil mill effluent (POME) is wastewater containing dissolved materials with concentrations above the threshold. POME processing in Indonesia with an open pond system is less efficient because it requires large areas and causing greenhouse gas effects. In this study two methods were used, chemical method through electrocoagulation process and biologically by adding indigen bacteria. This study aims to determine the effect of stress on the adapter toward the performance of the electrocoagulation system, incubation time of indigen bacterial consortium and the effect of electrocoagulation conditions after the addition of a bacterial consortium in reducing oil and fat content, COD, pH, TSS, TDS, Fe and Cu metals. In the electrocoagulation method, used iron as electrode with a variation of adapter voltage 1.5, 3, 4.5 and 6 V, while the biologycally using bacteria that is Bacillus toyonensis and Stenotrophomonas rhizophila. The results showed that the best results of the use of electrocoagulation methods for oil and fat removal were 93.27%, COD was 85.71% at a voltage of 6 V and for 6 hours, TDS was 39% at a voltage of 6 V for 3 hours, TSS was 84%, Cu metal was 46% at a voltage of 3 V for 6 hours while pH and Fe metal increased at a voltage of 6 V for 6 hours namely pH to 11.39 and metal Fe at 92.35%. The addition of indigen bacteria the best results for removal of oil and fat was 74.62%, COD was 52.44%, TSS was 43.11% and pH reached 6.38 at the end of the incubation time for 6 days while for the value of TDS, metal Fe and Cu metal experienced the highest increase with efficiency as follows: 21.42% of TDS, 5.3% of Fe metal and 64.70% Cu metal. The results of combining two methods, namely electrocoagulation at a voltage of 6 V for 6 hours after the addition of effective bacterial consortium can reduce oil and fat levels to 87.39%, COD to 56.70%, TDS to 0.42%, Cu Metal to 23.33% and pH reached 8.82 while for TSS and Fe metal values increased by 15.88% and 93.74% in palm oil wastewater, respectively.
