Removal of COD and colour from AT-POME by heterogeneous fenton like process using iron Ore aggregate

Abstract

The production of palm oil mill effluent (POME) kept increasing every year in Malaysia and it is needed a proper treatment before can be discharged into water source. Recently, Fenton process have gained attention of researchers because of its effectiveness in removing organic pollutant. In this research, the ferrous ion (Fe2+) used in the experiment come from iron ore in which acts as a catalyst for Fenton process. The determination of COD and color removal were done through heterogeneous Fenton process. By using Box- Behnken Design (BBD), the design and optimization of the performance for the process can be determined. The maximum removal of COD and color were 30.8% and 75.2% respectively. Compared with nZVI as catalyst, the removal of COD and color were 67.72% and 90.88% respectively. From the Design of Experiment software (DOE), the predicted result for both COD and color removal were 27% and 69% while the actual result were 30.8% and 75.2% for COD and color removal. As there are decreasing value of COD and color after the process, this research can be suggested as one of the treatment method for AT-POME.
