Abstract

Biohydrogen production from carbohydrate rich organic wastes by fermentation route emerges as a sustainable option for renewable energy generation. Application of membrane technology in fermentation process can be beneficial as the membrane facilitate in removing the H2 generation inhibitors from the fermentation reaction, such as volatile fatty acids (VFA) and alcohols and improves the process yield. In the present study a novel nickel oxide (NiO) based ceramic catalytic membrane is developed on clay-alumina tubular support withan intermediate bentonite clay coating for application in membrane bioreactor (MBR) process. The prepared membrane showed highly hydrophilic surface involving static water contact angle of 320. A reduction in the clean water permeability (CWP) ofmembrane was observed due to the surface coating, 25 Lm-2h-1bar-1in comparison with that of the pristine support,105 Lm-2h-1bar-1.From FESEM and EDX analysis, impregnation of NiO,~28-29 (wt%) was evident on the membrane surface.Further, VFA rejection efficiency of the catalytic membrane was observed high with respect to butyric acid (50%) and acetic acid (60%) compared to thepristine support (30–40%). The membranes were used ina batch mode cylindrical bioreactor (7 L)made with stainless steelfor the dark fermentation processutilizing simulated molasses wastewater having initial COD of 8000 mg/L to produce biohydrogen under anaerobic condition in the presence of Clostridium sp. with controlled pH (6-7), temperature 35-400C and stirring conditions (300 rpm).The performance efficiency of fermentation process was compared in three types of system: i) without membrane; ii) with pristine supports and iii) with catalytic membranes.After 120 h of fermentation, biohydrogen generation was recorded as 0.15, 0.35 and 0.48 mol H2/mol of carbohydrate in the systems (i), (ii) and (iii) respectively. Withappropriate optimizationof the wastewater composition in terms of carbohydrate content, use of microorganism consortium such as Clostridium. sp. and Enterobactor. sp. and employing a novel bi-metallic (Ni-Fe) based catalytic membrane can enhance the biohydrogen yield towards establishing a sustainable waste-to-energy production pathway.
