Energy Recovery from Herbal Wastewater and Monosodium Glutamate Wastewater through Anaerobic Co-Digestion

Anaerobic continuous stirring tank reactor (CSTR) was employed for biohydrogen production by anaerobic co-digestion from the mixture of herbal wastewater (HW) and monosodium glutamate (MGW). A series blend volumetric proportions (MGW/HW), organic loading rates (OLR) were used as control strategy evaluated optimal production. The highest 7260±7.7 mL L -1 d attained at proportion 15%, OLR 41 g COD while yield 508.9±7.2 removed observed same conditions. This study demonstrated feasibility effectiveness enhanced adding MGW to compensate low nitrogen content HW.
