Optimization of Conditions for Biohydrogen Production from Industrial Waste by Anaerobic Co-Digestion

Food processing wastewater contains biodegradable organic matter, and biogas and hydrogen content varies with the operational conditions of the anaerobic digester and may be useful control parameter. Up flow anaerobic sludge blanket reactor (UASB) was investigated for the treatment of low biodegradable composite chemical wastewater, which was complex in nature. In Phase-I, experiments were carried out in a laboratory scale batch reactor fed with sugar industrial wastewater with different concentrations. During batch mode operation the various characteristics of sugar industrial wastewater such as pH, TS, TDS, TVSS, BOD_5,20, etc. were studied. The variation among these characteristics with respect to days can be plotted to know the maximum growth of microorganisms in batch reactor. The batch process is mainly started for the acclimatization process (growing of microorganisms) and to find the steady state condition for the reactor which shows optimum conditions.
