BIOGAS PRODUCTION FROM CO-DIGESTION OF TEXTILE DYE AND RICE HUSK USING AGARICUS HETEROCYSTIS

摘要

The waste generated from the textile industry is used for the production of biogas under the anaerobic digestion method. This study investigated the effect of various parameters such as Temperature 27 °C – 31 °C, pH 8-10, Inoculum concentration 35-55 ml on the textile dye with rice husk by the Agaricus heterocystis for biogas production using Response surface methodology. Maximum biogas yield 93 ml was obtained under the optimized condition of pH 9, Temperature 29 °C, and Inoculum volume 45 ml. The modified Gompertz model was used for maximum biogas production (1140 ml) from reactor 1 of textile dye (100 ml), rice husk (20 g), and inoculum volume (45 ml). The maximum biogas production (350 ml) was obtained under the optimized condition of Incubation time 144 h; Dye 100 ml/L and Rice husk 20 mg/L under the classical method. Produced biogas was confirmed and analyzed the composition: Methane – 78% and Carbon dioxide – 13% by Gas Chromatography (GC) method. The present study provided an efficient method for textile effluent co-digestion with rice husk for biogas production and also to overcome the textile dye disposal issue faced by leading textile industries.
