Performance enhancement of leaf vegetable waste in two-stage anaerobic systems under high organic loading rate: Role of recirculation and hydraulic retention time

Zuo, Zhuang; Wu, Shubiao; Qi, Xiangyang; Dong, Renjie - In: Applied Energy 147 (2015) C, pp. 279-286

Continuous laboratory-scale experiments were conducted on two-stage anaerobic systems treating vegetable waste (VW) to improve CH4 production. The acidogenic reactors were employed with a serial methanogenic reactor configuration with volume distribution ratios of 3L/4L and 3L/7L (acidogenic...

High-rate fermentative hydrogen production from beverage wastewater

Sivagurunathan, Periyasamy; Sen, Biswarup; Lin, Chiu-Yue - In: Applied Energy 147 (2015) C, pp. 1-9

Hydrogen production from beverage industry wastewater (20g/Lhexose equivalent) using an immobilized cell reactor with a continuous mode of operation was studied at various hydraulic retention times (HRT, 8–1.5h). Maximum hydrogen production rate (HPR) of 55L/L-d was obtained at HRT 1.5h (an...
