Production of Biogas from Food Waste Using the Anaerobic Digestion Process with Biofilm-Based Pretreatment

چکیده
The production of biogas from food waste is a good approach to the minimization and increase in renewable energy. However, use as feedstock for currently poses difficulty due an ineffective hydrolysis process, which pretreatment procedure initial step conversion process. This restriction results polymers’ solubilization breakdown. has impact on volume produced during methanogenesis stage. It essential biodegradation organic compounds (OC) process generation. study focuses enhancement by anaerobic digestion (AD) (FW). FW was hydrolyzed immobilized biofilm digested anaerobically semi-continuous digester. Four different digesters including control were prepared. digester composed no had while other three biofilm-hydrolyzed with inoculum concentrations 10%, 30%, 50%. showed that 50% highest yield about 2000 mL/500 mL. 1523 mL, 753 502 mL respectively. Thus, analysis total volatile solid (TVS) reduction have increased 43.4% 30% 60% inoculum, only 29% control. Total chemical demand (TCOD) removal 29%, 33%, 43%, 56% control, 50%, respectively inoculum-to-feed ratio. From these results, ratio shown degradation based TVS TCOD reduction. Based this study, method can be considered promising biodegradation. Biogas high (2000 mL) hydraulic retention time (HRT = 20) days but HRT 15 also able produce significant amount (1400 production.

Production of Biogas by Using Food Waste
The current work focuses on the generating bio-gas from food waste produced by Mahendra Engineering College Canteen using anaerobic digestion process. Attempts have been made to optimize various parameters in order to determine the most favorable recipe for maximum biogas production from the digested food waste. The biogas yields have been determined using batch anaerobic thermophilic digestion...
متن کامل2. Production of Biogas by Anaerobic Digestion
Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...
