Penyahwarnaan Efluen Kilang Minyak Kelapa Sawit (POME) melalui Proses Pengoksidaan Fenton secara Berterusan menggunakan Limonit sebagai Pemangkin

Abstract

Palm oil industry has huge impact on the environment especially in Malaysia. The palm oil mill effluent (POME) is a liquid waste that contains organic compounds derived from degradable material and was easily decomposed by microorganisms. Today's POME treatment technology relies heavily on biological methods to reduce chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total organic carbon (TOC). However, these processes cannot decompose the color compounds found in POME. This study describes a study on potential uses of Fenton oxidation using limonite ore as catalyst to treat POME after biological treatment which was obtained from a palm oil mill. The results showed that only 50 mM of H2O2 could decolorize 800 - 1000 PtCo of the POME via continuous treatment with 1 hour retention time at pH 3.
