Abstract

High amounts of black liquor wastewater are generated from bioethanol production by using oil palm empty fruit bunches. It contains an alkaline solution (NaOH), so it is quite toxic for aquatic ecosystems if discharged directly into waters. Black liquor has been treated by coagulation method, and it still needs additional treatment. This study aimed to determine degradation of black liquor wastewater by selected white-rot fungi (WRF). Five different strains of WRF have been tested for their ability to decolorize black liquor on agar and liquid media. Out of five fungi studied, two fungi, Ceriporiopsis sp. and Phanerochaete chrysosporium, showed the capacity to grow more than 50% on agar medium. In liquid medium, the percentage of decolorization of 15,000 ppm coagulated and diluted black liquor ranged from 70 to 89% at 30 days depending on the fungal strain. Ceriporiopsis sp. showed the better ability to decolorize black liquor than P. chrysosporium. The performance of Ceriporiopsis sp was evaluated regarding decolorization of black liquor, chemical oxygen demand (COD), and mycelial dry weight both in coagulated black liquor and original black liquor. The color of original and coagulated black liquor can be decolorized up to 90.13 and 86.85%, respectively. COD in original and coagulated black liquor was reduced up to 70.17 and 40.09%, respectively. The presence of coagulant Poly Aluminum Chloride (PAC) inhibited degradation of black liquor by fungus. The result demonstrated that Ceriporiopsis sp has a potential alternative to treat black liquor wastewater.

Abstract

Pembuatan bioetanol dari tandan kosong kelapa sawit menghasilkan lindi hitam dengan karakteristik nilai COD tinggi dan nilai oksigen terlarut rendah. Lignin sebagai senyawa utama dalam lindi hitam dapat didegradasi dengan menggunakan oksidasi tinggi dari sistem radikal OH seperti metode Fenton. Setelah itu, lindi hitam tersebut dapat didekolorisasi. Tujuan penelitian ini adalah untuk mengetahui kondisi optimum variabel pH, konsentrasi FeSO4, dan konsentrasi H2O2 untuk mendekolorisasi lindi hitam dengan menggunakan metode desain komposit pusat. FeSO4 dan H2O2 digunakan untuk reagen Fenton. Proses pengadukan dilakukan di jar test dengan kecepatan 200 rpm selama 10 menit, kemudian kecepatan pengadukan diturunkan hingga 50 rpm selama 2 jam, dan disedimentasi 24 jam. Dekolorisasi tertinggi lindi hitam diperoleh sebesar 53% pada pH 13 dengan perbandingan volume H2O2 dan FeSO4 1: 1. Metode Fenton mampu mendekolorisasi air limbah lindi hitam dari proses bioetanol sebesar 52% pada pH 13 dengan rasio volume Metode permukaan respon merupakan metode yang baik untuk mengoptimasi variabel-variabel sehingga mampu meningkatkan efisiensi dekolorisasi air limbah lindi hitam. Dekolorisasi air limbah lindi hitam dapat ditingkatkan hingga mencapai 73% apabila pH, konsentrasi FeSO4, dan konsentrasi H2O2 yang digunakan masing-masing sebesar 6,64; 0,1 mM, dan 3,68 mM. Hal ini menunjukkan bahwa metode Fenton mempunyai potensi dalam mengatasi permasalahan air limbah lindi hitam pada proses pembuatan bioetanol.
