Abstract

Indeed, sugarcane is an essential crop in India and several types of wastes are produced from it such as molasses, bagasse,the distillery effluent, bagasse ash and press mud. Even though there is an extensive study carried out in ethanol production from sugarcane waste, there is also a need to explore bio-hydrogen production from it. In addition, the bio-hydrogen capacity of this waste can be compared with the codigestion of treated sludge in mesophilic conditions under dark fermentation for the effective production of bio-hydrogen. In this work, the experiments were carried out on a laboratory scale in a batch reactor fed with distillery effluent with press mud and treated sludge by different dilution ratios. During the batch mode operation various parameters such as pH, TS, TDS, TVSS, and bio-hydrogen yield were analyzed. The variation among these characteristics with respect to days is plotted to make out the maximum degradation, maximum growth of micro-organism and maximum bio-hydrogen yield in different batch reactors. The batch process is mainly started for identifying the best dilution ratio for the bio-hydrogen yield.
