The gradual scarcity of fossil fuel resources and associated environmental restrictions opens the research avenues worldwide to explore on clean energy sources like hydrogen as a renewable and sustainable energy source with a high energy content and no negative environmental effects. Various organic wastes with high carbohydrate content are mostly used to produce biohydrogen by fermentation process in presence of suitable bacteria. In this regard, integrating a ceramic membrane into a fermentative reactor may be a desirable way to increase the production of biohydrogen. The present study is aimed to construct a novel ceramic membrane bioreactor where molasses wastes are fermented in presence of anaerobic bacteria Clostridium sp. to produce biohydrogen through dark fermentation process. The bioreactor study was done in a SS bioreactor (7 L) in batch mode with simulated molasses wastewater with controlled pH, temperature and stirring condition. Metal oxide based ceramic membrane was prepared on clay-alumina support and characterised by FESEM, EDX, FTIR etc. The performance was further measured in terms of clean water permeability (CWP), % recovery of volatile fatty acid,% production of hydrogen and chemical oxygen demand (COD) reduction. The gas samples and VFA were analysed using GC and HPLC, respectively. Biohydrogen production started after 48 h of fermentation in membrane bioreactor, reaching its maximum yield of 0.48 mol H2/mol of carbohydrate after 120 h and wastewater COD was reduced by ~ 40 %.Optimization of wastewater composition, external physicochemical and microbial environment along with the ceramic membrane characteristics can be crucial in enhancement of bioH2 yield towards establishing a sustainable pathway for waste to energy production.
