Effect of co-digestion with various slurry temperatures on sugarcane — rice husk: Methane potential

Abstract

In this study, the performance of anaerobic co-digestion of sugar cane bagasse and rice husk in the ratio of 1:1, the digestion process is carried out by using floating drum type anaerobic digester under mesophilic conditions (30°C to 45°C) and thermophilic condition (46 °C to 55 °C) with an hydraulic retention time (HRT) of 30 days for both the conditions is investigated. The results indicated that the co-digestion of bagasse with rice husk is produced biogas and methane yield 0.68 m3 and 58 % is obtained at thermophilic condition compare to mesophilic condition, therefore thermophilic condition is recommended as the optimal methane and biogas production for the co-digestion of sugarcane bagasse and rice husk.
