Detoxification of Distillery Wastewater by AOP Fenton for the Enhancement of Biogas Production

Distillery wastewater from the bioethanol industry contains a high level of organic content which can be converted into biogas. However, presence toxic compounds in this could inhibit biogas production. Therefore, prior detoxification distillery is required. Fenton, one Advanced Oxidation Process (AOP) methods, was selected due to its performance degrade pollutants, short reaction time, and process simple easy. Additionally, method also used as pretreatment for This paper aims study improvement production by applying AOP Fenton method. The experiment consists two stages, first application order determine effect on concentration COD some such phenol sulfate. second stage through anaerobic digestion process, carried out under conditions raw materials: (i) without control (ii) that has been treated with pretreatment. Results show remarkable decrease 45%, (63%), sulfate (18,6%) after Fenton. It implies significantly detoxified wastewater. As pretreatment, increased 33% higher, 2.399 mL (without pretreatment) 3.191 (with pretreatment). indicates biodegradability Thus, it easier
